          To load paper, adjust print positions, etc. the printer cover
          must be opened. This is done by lifting upwards at the printer
          front; the cover is hinged to the rear and can be tipped up.
          Thereby the print module (see section 2.2) and the paper
          transport unit (see section 2.3) are revealed; further the VFU
          (V_ertical F_ormat U_nit) can be seen on the lower left side (see
          section 2.4) and the colour ribbon to the front of the print
          module (see section 2.5). 
           
          The printer is supported by a printer stand and has at the rear a
          paper spreader and a paper deflector installed (see section
          4.1).

          The below description points at the various controls attended by
          the operator. The actual procedures in operating are described
          later on.

          Figure 2: Control panel. 
           
          POWER ON/OFF                  - a mains power switch is located
          (not shown)                     at the rear of the printer. It
                                          can be switched ON, and left in
                                          the ON position, first time the
                                          printer is operated. The printer
                                          will then be switched on/off as
                                          the system is switched on/off. 
                                           
          1)  LINE ON/OFF               - in the ON position the printer
              switch                      can receive data for printing. 
                                           
                                          The switch always has to be in
                                          the OFF position when the opera-
                                          tor loads paper, replaces colour
                                          ribbon, and so on. While in the
                                          OFF position the indicator lamp
                                          will ligth (EOP indicator). 
                                           \f

                   2)  PAPER LF/TOF              - when pressed to the LF position
              switch                      and rapidly returned to its
                                          normal position, this control
              (LF = L_ine F_eed)            feeds the paper one line. 
              (TOF = T_op O_f F_orm)          
                                          When pressed to the LF position
                                          and held pressed, this control
                                          continously feeds the paper until
                                          the switch is returned to normal
                                          position. 
                                           
                                          When pressed to the TOF position,
                                          this control causes the paper to
                                          advance to the next top-of-form
                                          position. Press once for each
                                          form to be feed. 
                                           
                                          The PAPER LF/TOF switch only
                                          functions when the LINE control
                                          is switched to the OFF position.
                                           
          3)  EOP                       - when the paper is running low,
              indicator/alarm             the EOP indicator is lit (the
                                          indicator is also lit when
              (EOP = E_nd o_f P_aper)        switching the LINE control to the
                                          OFF position). Upon printing the
                                          last form, further an intermit-
                                          tent acoustic alarm is heard and
                                          printing is blocked. 
                                           
                                          The acoustic signal is cancelled
                                          by switching the LINE control to
                                          the OFF position. The EOP indica-
                                          tor will be lit until paper has
                                          been replenished and a PAPER TOF
                                          control has been performed. 
                                           \f

                   Alarm                         - the acoustic alarm is also ap-
                                          plied either when receiving a
                                          BELL code, or when a printer
                                          failure occurs. 
                                           
                                          The duration of a BELL alarm is
                                          about 1 second; it is mostly used
                                          to signal a message received at
                                          the printer. 
                                           
                                          Other alarms cannot be cancelled
                                          rightaway, except when switching
                                          off power (see discussion later
                                          on).

                   The print module is released by pulling outwards in the locking
          levers as shown. The print module is automatically pulled up into
          a position of repose by spring power. 
           
          When in the tilted position, the margin indicators can be ad-
          justed. \f

          The print head m_u_s_t_ _a_l_w_a_y_s_ be positioned inbetween the two margin
          indicators; the margins are set by sliding the indicators along
          the graduated position scale. The right-hand margin setting never
          must allow printing outside the paper form. 
           
          To support the final paper adjustment three index marks are
          available: 
                                         
                                        - horizontal printposition is

                                        - vertical position of printed line
                                          is indicated by a mark to the
                                          right on the print head, 
                                           
                                        - a reference mark 15 lines away
                                          from position of printed line is
                                          found at left-hand tractor.

                                          paper transport by means of a
                                          punched tape. To insert a tape
                                          the flap is pressed upwards until
                                          it reaches a crank position where
                                          it remains.

          Before operating the printer, use the following main check
          points:  
           
          -  self-test to be enabled, or not 
          -  colour ribbon condition 
          -  correct VFU tape loaded 
          -  sufficient amount of paper loaded 
          -  paper adjustments 
           
          The procedings involved in maintaining these conditions are
          discussed below.

          The printer should never be switched on without having a VFU
          tape, a colour ribbon, and a paper form installed. Especially,
          take care that the printer is never allowed to print on the
          platen when stripped of paper. 
           
          If power is switched on and the LINE control is in the OFF posi-
          tion, the printer will automatically perform a self-test proce-
          dure, whereby all printing functions are checked. If the self-test
          is not wanted, the LINE control should be in the ON position
          before switching on power. The LINE control can then immediately
          be switched to the OFF position, if the printer is not yet ready
          to receive data for printing. 
           
          When power is applied and whenever the LINE control is switched
          from OFF to ON the print head moves to the left-hand margin
          position. 
           
          In order to enable printing the LINE control is set in the ON
          position; to disable printing the control is set to the OFF
          position.

          The tape is prepared according to 4.2. 
           
          The LINE control must be in the OFF position. The printer cover
          is opened and the flap of the VFU tape reader is pushed into the
          up-position. The tape is inserted so that the sprocket holes
                                          (smallest holes) are engaged with
                                          the sprocket wheel and so that
                                          the punched holes are positioned
                                          towards the printer. 
                                           
                                          The flap is then lowered. A check
                                          is made to ensure correct load-
                                          ing. 
                                           
                                           
           
          Whenever a VFU tape has been loaded, it will be necessary to
          adjust the paper transport in accordance with 3.4.2.

          The LINE control must be in the OFF position. 
           
                                                  The printer cover is
                                                  opened. The print module
                                                  is released and tilted to
                                                  the service position. The
                                                  paper transport unit is
                                                  tilted to a position of
                                                  45 backwards-sloping.

                                                   The paper is entered from the
                                          rear and pushed into the printer.
                                          From below the platen it can be
                                          pulled through in order to be
                                          loaded on the tractors. The
                                          printing side has to face down-

                                                The paper transport unit is
                                                restored to its working
                                                position; at the same time
                                                the entering paper is
                                                pulled backwards to avoid
                                                crumpling under the unit. 
                                                 
                                                The left-hand tractor is
                                                then positioned in conjunc-

                                                margin setting and locked.
                                                The rigth-hand tractor is
                                                sligthly pulled to the
                                                rigth when locking in order
                                                to strech the paper form. 
                                                 
          The out-going paper is folded by gravity force and the stacking
          of the printed forms must be allowed in the centre of the
          out-going paper path. 
           
          Whenever paper has been loaded, it is necessary to adjust for
          correct vertical print positioning; it may also be necessary to
          adjust margin settings. If the margin settings do not have to be
          adjusted, the print module can be restored to its work position.
          Adjustments are performed according to 3.4.

          Whenever a VFU tape, or a paper form, has been loaded, it will be
          necessary to adjust for correct vertical print positioning.
          Having loaded a new paper form, it may also be necessary to
          adjust the margin settings (horizontal print positioning). 
           
          Other adjustments are not necessary; adjustment according to
          paper thickness is performed automatically. 
           
          The adjustments are performed with the printer cover opened and
          the LINE control in the OFF position. \f

          Note: The print head cannot print beyond the rigth margin. If the
                line length does not correspond to the margin setting the
                excessive characters will be printed on the next line.
                Thereby introducing an extra line feed that will disturb
                the programmed vertical format control. 
           
                                          The print module is lowered to
                                          its working position. The print
                                          head is moved to the left margin
                                          position by rapidly switching the
                                          LINE control from OFF to ON, and
                                          back to OFF. 
           
          Both tractors are unlocked and the paper is adjusted sidewards so
          that the utmost left-hand print position coincides with the index
          mark on top of the print head. The tractors are locked in that
          position; the right-hand tractor should be sligthly pulled to the
          rigth when locking. 
           \f

          If another initial print position is desired, the left-hand mar-
          gin indicator is slid to that position, using the graduaded scale
          as reference (the print module is released and tilted to the ser-
          vice position to do so). This procedure also applies when correc-
          ting a misadjustment of one character position as it will be much
          easier to adjust the margin indicator one character position to
          the right or left than it would be to position the paper tractors
          likewise.

          The vertical print positioning is a matter of synchronizing the
          VFU tape and the paper form. 
           
          The tear-off line between two formats is positioned just under

                                                     control. The knob is
                                                     then returned to its
                                                     normal position (see
                                                     below for illustration
                                                     of knob).

          Note: After this procedure has been accomplished, the adjustment
                knob must not be readjusted - doing so, the synchronizing
                of VFU and paper form will be spoiled. 
           
          If, however, another line than line 1 is to be the first printing
          line, then pull out the adjustment knob again and adjust the
          tear-off line against the reference mark on the left-hand trac-
          tor. Then the first printing line (top of form) will be line 15.
          Any other line between 1 and 15 can be chosen as the first prin-
          ting line by stepping the PAPER LF control while keeping the ad-
          justment knob in the pulled-out position. Each stepping by the
          PAPER LF control will reduce the line number by 1. For instance,
          10 steppings give line 5 (15-10) as the first printed line. 
           
                                          Note: This proceeding will not
                                          change the programming of the VFU
                                          tape; it only allows for the over-
                                          all form of the printouts to be
                                          moved relative to the paper form.

          The printer sounds an acoustic alarm in case of printer failures.
          A number of printer monitoring functions can cause the alarm
          (besides the end-of-paper status and the bell code status as
          pointed at earlier). 
           
          An alarm may as well be caused by outside interference. Such an
          alarm, however, can be cancelled by switching the LINE control
          OFF and ON, or by switching the mains power supply off and on. 
           
          If the alarm still remains, one should switch off power and check
          that all operating procedures (concerning VFU tape, colour rib-
          bon, paper form, etc.) have been properly executed. Also wrong
          programming of the punched VFU tape could cause the alarm. If no
          remedies are found, call a service technician.

          The programmed tape length after splicing must be in the range
          75-160 holes (channel 4). Otherwise the short program is repeated
          a number of times in order to obtain the required length.

          The tape should be punched to contain an extra TOF hole. When
          splicing, the tape is folded so that the two outer TOF holes
          coincide and the two free tape ends are cut at the same time. 
           
           
           
           
           
           
           
           
           
           
           
           
           
           
          A special splicing tape is used. Both ends of the VFU tape must
          be closely joined without overlap, when splicing. (Splicing can
          be supported by turning the minipunch over and using the guide
          pins as fixture). The splicing tape is applied on both sides of
                                               the VFU tape. The splicing
                                               tape must not overlay
                                               punched holes. If this is
                                               so, the holes overlaid are
                                               re-punched.

          To load paper, adjust print positions, etc. the printer cover
          must be opened. This is done by lifting upwards at the printer
          front; the cover is hinged to the rear and can be tipped up.
          Thereby the print module (see section 2.2) and the paper
          transport unit (see section 2.3) are revealed; further the VFU
          (V_ertical F_ormat U_nit) can be seen on the lower left side (see
          section 2.4) and the colour ribbon to the front of the print
          module (see section 2.5). 
           
          The printer is supported by a printer stand and has at the rear a
          paper spreader and a paper deflector installed (see section
          4.1).

          Figure 2: Control panel. 
           
          POWER ON/OFF                  - a mains power switch is located
          (not shown)                     at the rear of the printer.  
                                           
          1)  LINE ON/OFF               - in the ON position the printer
              switch                      can receive data for printing. 
                                           
                                          The switch always has to be in
                                          the OFF position when the opera-
                                          tor loads paper, replaces colour
                                          ribbon, and so on. While in the
                                          OFF position the indicator lamp
                                          will ligth (EOP indicator).

                   2)  PAPER LF/TOF              - when pressed to the LF position
              switch                      and rapidly returned to its
                                          normal position, this control
              (LF = L_ine F_eed)            feeds the paper one line. 
              (TOF = T_op O_f F_orm)          
                                          When pressed to the LF position
                                          and held pressed, this control
                                          continously feeds the paper until
                                          the switch is returned to normal
                                          position. 
                                           
                                          When pressed to the TOF position,
                                          this control causes the paper to
                                          advance to the next top-of-form
                                          position. Press once for each
                                          form to be feed. 
                                           
                                          The PAPER LF/TOF switch only
                                          functions when the LINE control
                                          is switched to the OFF position.
                                           
          3)  EOP                       - when the paper is running low,
              indicator/alarm             the EOP indicator is lit (the
                                          indicator is also lit when
              (EOP = E_nd o_f P_aper)        switching the LINE control to the
                                          OFF position). Upon printing the
                                          last form, further an intermit-
                                          tent acoustic alarm is heard and
                                          printing is blocked. 
                                           
                                          The acoustic signal is cancelled
                                          by switching the LINE control to
                                          the OFF position. The EOP indica-
                                          tor will be lit until paper has
                                          been replenished and a PAPER TOF
                                          control has been performed.

                   Alarm                         - the acoustic alarm is also ap-
                                          plied either when receiving a
                                          BELL code, or when a printer
                                          failure occurs. 
                                           
                                          The duration of a BELL alarm is
                                          about 1 second; it is mostly used
                                          to signal a message received at
                                          the printer. 
                                           
                                          Other alarms cannot be cancelled
                                          rightaway, except when switching
                                          off power (see discussion later
                                          on).

          indicators; the margins are set by sliding the indicators along
          the graduated position scale. The right-hand margin setting never
          must allow printing outside the paper form. 
           
          To support the final paper adjustment three index marks are

                                                   Each tractor has four paper hol-
                                          ding flaps, two on top and two
                                          below. The flaps facilitate that
                                          the paper is kept engaged with
                                          the sprocket belt.

                                          The VFU controls the vertical
                                          paper transport by means of a
                                          punched tape. To insert a tape
                                          the flap is pressed upwards until
                                          it reaches a crank position where
                                          it remains.

          Before operating the printer, use the following main check
          points:  
           
          -  self-test to be enabled, or not 
          -  colour ribbon condition 
          -  correct VFU tape loaded 
          -  sufficient amount of paper loaded 
          -  paper adjustments 
           
          The procedings involved in maintaining these conditions are
          discussed below. 
           
           
3_._1_ _ _ _ _ _ _ _P_o_w_e_r_ _O_n_ 3.1
           
          The printer should never be switched on without having a VFU
          tape, a colour ribbon, and a paper form installed. Especially,
          take care that the printer is never allowed to print on the
          platen when stripped of paper. 
           
          If power is switched on and the LINE control is in the OFF posi-
          tion, the printer will automatically perform a self-test proce-
          dure, whereby all printing functions are checked. If the self-test
          is not wanted, the LINE control should be in the ON position
          before switching on power. The LINE control can then immediately
          be switched to the OFF position, if the printer is not yet ready
          to receive data for printing. 
           
          When power is applied and whenever the LINE control is switched
          from OFF to ON the print head moves to the left-hand margin
          position. 
           
          In order to enable printing the LINE control is set in the ON
          position; to disable printing the control is set to the OFF
          position.

          The tape is prepared according to 4.2. 
           
          The LINE control must be in the OFF position. The printer cover
          is opened and the flap of the VFU tape reader is pushed into the
          up-position. The tape is inserted so that the sprocket holes
                                          (smallest holes) are engaged with
                                          the sprocket wheel and so that
                                          the punched holes are positioned
                                          towards the printer. 
                                           
                                          The flap is then lowered. A check
                                          is made to ensure correct load-
                                          ing. 
                                           
                                           
           
          Whenever a VFU tape has been loaded, it will be necessary to
          adjust the paper transport in accordance with 3.4.2.

                                                the entering paper is
                                                pulled backwards to avoid
                                                crumpling under the unit.

          The out-going paper is folded by gravity force and the stacking
          of the printed forms must be allowed in the centre of the
          out-going paper path. 
           
          Whenever paper has been loaded, it is necessary to adjust for
          correct vertical print positioning; it may also be necessary to
          adjust margin settings. If the margin settings do not have to be
          adjusted, the print module can be restored to its work position.
          Adjustments are performed according to 3.4.

          Whenever a VFU tape, or a paper form, has been loaded, it will be
          necessary to adjust for correct vertical print positioning.
          Having loaded a new paper form, it may also be necessary to
          adjust the margin settings (horizontal print positioning). 
           
          Other adjustments are not necessary; adjustment according to
          paper thickness is performed automatically. 
           
          The adjustments are performed with the printer cover opened and
          the LINE control in the OFF position. \f

                                          head is moved to the left margin
                                          position by rapidly switching the
                                          LINE control from OFF to ON, and
                                          back to OFF. 
           
          Both tractors are unlocked and the paper is adjusted sidewards so
          that the utmost left-hand print position coincides with the index
          mark on top of the print head. The tractors are locked in that
          position; the right-hand tractor should be sligthly pulled to the
          rigth when locking. 
           \f

          If another initial print position is desired, the left-hand mar-
          gin indicator is slid to that position, using the graduaded scale
          as reference (the print module is released and tilted to the ser-
          vice position to do so). This procedure also applies when correc-
          ting a misadjustment of one character position as it will be much
          easier to adjust the margin indicator one character position to
          the right or left than it would be to position the paper tractors
          likewise.

          The vertical print positioning is a matter of synchronizing the
          VFU tape and the paper form. 
           
          The tear-off line between two formats is positioned just under
          the white index mark at the right-hand side of the print head. To
          feed the paper, use the PAPER LF control. The adjustment knob is
                                                     then pulled out and by
                                                     turning the knob the
                                                     tear-off line is alig-
                                                     ned against the index
                                                     mark. Keeping the ad-
                                                     justment knob in the
                                                     pulled-out position,
                                                     actuate the PAPER TOF
                                                     control. The knob is
                                                     then returned to its
                                                     normal position (see
                                                     below for illustration
                                                     of knob). 
 \f

          Note: After this procedure has been accomplished, the adjustment
                knob must not be readjusted - doing so, the synchronizing
                of VFU and paper form will be spoiled. 
           
          If, however, another line than line 1 is to be the first printing
          line, then pull out the adjustment knob again and adjust the
          tear-off line against the reference mark on the left-hand trac-
          tor. Then the first printing line (top of form) will be line 15.
          Any other line between 1 and 15 can be chosen as the first prin-
          ting line by stepping the PAPER LF control while keeping the ad-
          justment knob in the pulled-out position. Each stepping by the
          PAPER LF control will reduce the line number by 1. For instance,
          10 steppings give line 5 (15-10) as the first printed line. 
           
                                          Note: This proceeding will not
                                          change the programming of the VFU
                                          tape; it only allows for the over-
                                          all form of the printouts to be
                                          moved relative to the paper form.

          The printer sounds an acoustic alarm in case of printer failures.
          A number of printer monitoring functions can cause the alarm
          (besides the end-of-paper status and the bell code status as
          pointed at earlier). 
           
          An alarm may as well be caused by outside interference. Such an
          alarm, however, can be cancelled by switching the LINE control
          OFF and ON, or by switching the mains power supply off and on. 
           
          If the alarm still remains, one should switch off power and check
          that all operating procedures (concerning VFU tape, colour rib-
          bon, paper form, etc.) have been properly executed. Also wrong
          programming of the punched VFU tape could cause the alarm. If no
          remedies are found, call a service technician.

          The tape should be punched to contain an extra TOF hole. When
          splicing, the tape is folded so that the two outer TOF holes
          coincide and the two free tape ends are cut at the same time. 
           
           
           
           
           
           
           
           
           
           
           
           
           
           
          A special splicing tape is used. Both ends of the VFU tape must
          be closely joined without overlap, when splicing. (Splicing can
          be supported by turning the minipunch over and using the guide
          pins as fixture). The splicing tape is applied on both sides of
                                               the VFU tape. The splicing
                                               tape must not overlay
                                               punched holes. If this is
                                               so, the holes overlaid are
                                               re-punched.

                                                    rollers. If a two-colour
                                                    ribbon is used, the
                                                    black area of the rib-
                                                    bon should be the up-
                                                    permost. 
           
          Note: Ribbon winds off/on at >top> of right-hand spool; 
                at >bottom> of left-hand. 
           
          Note: The ends of the ribbon are fitted with rivets which actuate
                the turning mechanism of the ribbon. Should ribbons other
                than the recommended be used, these must be fitted with the
                         rivets mentioned.

          Printerens overdel skal åbnes, når der skiftes papir, VFU
          strimmel, farvebånd eller lignende. Overdelen er hængslet bagtil;
          den åbnes ved at løfte foran. Når overdelen er åbnet, kan man se
          skrivemodulet (jvf. 2.2) og papirtransporten (jvf. 2.3); yder-
          ligere findes den vertikale formatstyreenhed (VFU - Vertical
          Format Unit) forneden til venstre set fra ydersiden (jvf. 2.4) og
          farvebåndet foran på skrivemodulet (jvf. 2.5). 
           
          Printeren installeres på et bord og bagpå printeren monteres et
          papirføringsudstyr bestående af et trådgitter og en bøjle (jvf.
          4.1).

          POWER ON/OFF                  - hovedafbryderen findes på prin-
          (ikke vist)                     terens bagside. Den kan forblive
                                          tændt efter første betjening. 
                                          Printeren vil så automatisk blive
                                          tændt/slukket, når systemet
                                          tændes/slukkes. 
                                           
          1)  LINE ON/OFF               - med kontakten i ON stilling kan

                                          Kontakten skal altid være i OFF
                                          stilling, når operatøren sætter
                                          papir i, skifter farvebånd eller
                                          lign. 
                                           
                                          Når kontakten er i OFF stilling,
                                          lyser indikatoren (EOP indika-

                                          føres papiret en linie frem. 
              (LF = L_ine F_eed

                   = ny side)             igen slippes. 
                                           
                                          Når kontakten trykkes i TOF
                                          stilling, føres papiret frem til
                                          ny side. Tryk en gang for hver ny
                                          side, papiret skal føres frem. 
                                           
                                          PAPER LF/TOF kontakten virker
                                          kun, når LINE kontakten er i OFF
                                          stilling.

              indikator/advarselssignal   bart før papiret slipper op (den
                                          kan dog også være tændt, fordi
              (EOP = E_nd O_f P_aper         LINE kontakten er skiftet fra ON
                   = papir slut)          til OFF). Når sidste side er ud-
                                          skrevet, høres desuden et advar-
                                          selssignal (afbrudt tone), hvor-
                                          efter udskrivningen blokeres. 
                                           
                                          Alarmtonen kan stoppes ved at
                                          skifte LINE kontakten fra ON til
                                          OFF. EOP indikatoren slukkes
                                          først, når nyt papir er sat i og
                                          der er udført en PAPER TOF

          Forud for drift af printeren, benyt følgende kontrolpunkter: 
           
          -  selvtest ønsket eller ej, 
          -  farvebåndets tilstand, 
          -  korrekt VFU strimmel isat, 
          -  printer instillinger. 
           
          De fremgangsmåder, der indgår i opretholdelsen af disse
          driftsbetingelser, er beskrevet i det følgende. 
           
           
3_._1_ _ _ _ _ _ _ _S_t_a_r_t_ 3.1
           
          Printeren bør aldrig startes, uden der er monteret farvebånd, VFU
          strimmel samt papir. Sørg for, at printeren aldrig skriver på
          selve skrivevalsen uden papir isat - det er ikke tilladt. 
           
          Når printeren startes og LINE kontakten er i OFF stilling, vil
          printeren udføre en selvtest, hvorved alle funktioner gennem-
          prøves. Hvis selvtesten ikke er ønsket, skal LINE kontakten
          stilles i ON stillingen, før start. (LINE kontakten kan så umid-
          delbart derefter stilles i OFF stilling, hvis printeren endnu
          ikke er klar til drift). 
           
          Når printeren startes (og hver gang LINE kontakten skiftes fra
          OFF til ON), vil skrivehovedet flytte sig ud til venstre
          margenposition. 
           
          Udskrivning er mulig, når LINE kontakten stilles i ON stilling;
          ikke mulig, når den stilles i OFF stilling.

                                            ledes at strimlens øvrige hul-
                                            ninger vender ind mod printer-
                                            en. 
           
                                            Tilholderhåndtaget slås ned
                                            igen til lukket stilling. Kon-

                                            isat. 
           
          Efter isætning af en VFU strimmel, er det nødvendigt at indstille
          papirfremføringen som beskrevet i pkt. 3.4.2.

                                          således at papiret strammes i

          Papiret, der forlader printeren, foldes alene ved egen tyngde og
                   stakningen skal derfor foregå i centerlinien for papirudløbet. 
           
          Hver gang nyt papir isættes i printeren, skal den vertikale
          papirindstilling omjusteres; det kan også være nødvendigt at
          justere margenpositionerne. Hvis margenpositionerne ikke skal
          ændres, kan skrivemodulet nu vippes tilbage til arbejdsstilling.
          Papirindstillingerne udføres i henhold til pkt. 3.4.

          Efter isætning af VFU strimmel eller papir, skal printeren
          indstilles med henblik på korrekt vertikal skrivepositionering.
          Når der sættes et nyt papirformat i printeren, vil det desuden
          oftest være nødvendigt også at indstille margenpositionerne påny
          (horisontal skrivepositionering). 
           
          Andre indstillinger er ikke nødvendige; printeren indstiller sig
          automatisk efter den papirtykkelse, der anvendes. 
           
          Indstillingerne i det følgende udføres med LINE kontakten i OFF
          stilling og overdelen åbnet.

                                               hurtigt at skifte LINE
                                               kontakten fra OFF til ON og
                                               tilbage til OFF. 
           
          Begge papirfremføringsenheder frigøres og papiret flyttes i
          tværretningen indtil yderste venstre skrivepostion på papiret
          falder sammen med indekseringsmærket ovenpå skrivehovedet. 
          Fremføringsenhederne låses i denne position; den højre enhed
          trækkes let mod højre, idet den låses. 
           \f

          Hvis en anden begyndelsesposition for udskrivningen ønskes, kan
          venstre margenstop flyttes langs ad referanceskalaen til den
          ønskede position (for at kunne gøre dette, frigøres skrivemodulet
          og vippes i servicestilling). Denne fremgangsmåde benyttes også
                   med fordel, når der er der er tale om at finindstille margenpo-
          sitionerne +/- en tegnposition, - det er ulig nemmere at flytte
          margenpositionerne lidt til venstre eller højre, end det er at
          flytte fremføringsenhederne tilsvarende.

          Den vertikale skrivepositionering opnås ved at synkronisere VFU
          strimlen og papirformatet. 
           
          Afrivningslinien mellem to formater indstilles lige under indeks-
          seringsmærket på højre side af skrivehovedet. Papiret føres frem
          ved brug af PAPER LF kontakten. Indstillingshåndhjulet trækkes
                                                  herefter ud, og ved at
                                                  dreje håndtaget indstil-

                                                  udfor mærket. Stadig med
                                                  håndtaget trukket ud,
                                                  aktiveres nu PAPER TOF
                                                  kontakten. Håndtaget kan
                                                  så slippes.

          Bemærk: Efter at denne indstilling er udført som beskrevet, må
                  indstillingshåndhjulet ikke efterjusteres - i så fald vil
                  synkroniseringen mellem VFU og pairformat blive ødelagt. 
           
                   Hvis man imidlertid ønsker en anden linie som første skrivelinie
          end linie 1 på papiret, kan man igen trække indstillingshåndtaget
                   ud og føre afrivningslinien frem til sammenfald med indekserings-
          mærket på venstre fremføringsenhed. I så fald bliver den første
          udskrevne linie (top-of-form), linie 15 på papiret. En hvilken
          som helst linie mellem linie 1 og 15 kan vælges som den første
          skrevne linie med trinvise enkelt-aktiveringer af PAPER LF kon-
          takten, stadig mens indstillingshåndhjulet holdes i udtrukket
          stilling. Hver aktivering af PAPER LF vil reducere linienummeret
          med 1, f.eks. vil 10 enkelt-aktiveringer medføre at linie 5
          (15-10) vil blive den første skrevne linie. 
           
                                          Bemærk: Denne fremgangsmåde
                                          ændrer ikke programmeringen af
                                          VFU strimlen, men bevirker en
                                          relativ forskydning mellem papir-
                                          format og udskrift.

          Printeren benytter et tonesignal som advarselssignal i tilfælde
          af funktionsfejl. En række forskellige overvågningsfunktioner kan
          udløse advarselssignalet (foruden end-of-paper situationen og
          bell tegnkoden som tidligere nævnt). 
           
          Signalet kan også udløses af udefra kommende forstyrelser
          (transmissionslinien). Et sådant signal vil kunne annulleres ved
          at skifte LINE kontakten fra ON til OFF og tilbage - eller ved at
          slukke med hovedafbryderen og tænde igen. 
           \f

          Hvis signalet ikke kan annulleres på denne måde, er det nødven-
          digt at slukke for printeren og kontrollere, at alle betjenings-
          procedurer (vedrørende VFU strimmel, farvebånd, papir, etc.) er
          korrekt udført. Også fejlprogrammering af den hullede VFU strim-
          mel kan forårsage advarselssignalet. Kan der ikke findes afhjælp-
          ningsmuligheder, tilkaldes en servicetekniker.

          Strimlen hulles, så den indeholder en TOF hulning svarende til
          det næste format. Når strimlen skal splejses, lægges strimmel-
          enderne sammen, således at TOF hulningerne ligger over hinanden
          og begge strimmelender skæres af på en gang. 
           
           
           
           
           
           
           
           
           
           
           
           
           
           
           
          Der benyttes en særlig splejsetape. Begge strimmelender skubbes
          tæt og nøjagtigt mod hinanden (uden overlapning) under splejs-
          ningen. (Håndhulleudstyret kan vendes og bruges som støtte ved
          splejsningen, idet VFU strimlen lægges nedover tappene). Splejse-
          tapen klæbes på begge sider af strimlen. Splejsetapen må ikke
          dække nogen af hulningerne - i givet fald skal disse efterhules.

          Båndstationen er skematisk vist i fig. 2. og de betegnelser, der
          refereres til i det følgende, er angivet. 
           
          Båndspolerne må højst være 10,5 tommer (26,7 cm) i diameter
          (svarende til en båndlængde på 2400 fod (731,5 m)). 
           
          Båndspolen, der skal monteres på båndstationen, placeres altid
          som nederste spole. Også bånd som skal tages af, skal være rullet
          op på den nederste spole. Den øverste spole forbliver således
          altid på båndstationen. 
           
          Bemærk: For at kunne indlæse ("skrive") data på et bånd, skal
                  båndspolen være forsynet med en skrivering. Denne ring
                  påvirker et kontaktsystem og muliggør dermed indlæsning
                  af data - uden ring kan man kun udlæse ("læse") data fra
                  båndet.

          Båndspolen placeres på nederste spolenav, således at båndet rul-
          les af spolen, når denne drejes med uret rundt. Spolen fasthol-
          des efter montering af en gummikrave på spolenavet. For at kunne
          skubbe spolen over gummikraven under monteringen, trykkes på ud-
          løseren i navets centrum (NB: på nogle modeller erstattet med en
          vippelås). Spolen skal skubbes jævnt ind og til fast anlæg mod
          bagflangen, medens man trykker på udløseren - har man sikret sig
          dette, slippes udløseren. Spolen er nu korrekt placeret i forhold
          til båndføringerne, klar til selve båndisætningen. 
           
                   Spolen drejes nu med uret, således at man får afrullet ca. 1,5
          meter bånd. Båndet føres frem til øverste båndspole via båndfør-
          ingen, som anvist med pile i fig. 2. Det vil være nødvendigt
          yderligere at afrulle bånd under isætningen, ligesom beskyttel-
          sesanordningen (feltspærringen) over læse-skrive-hovederne skal
          åbnes.

          Figur 2: Båndstationen (skematisk); isætning af bånd. 
           
          Den frie ende af båndet føres ind på den øverste spole, således
          at båndet rulles op, når spolen drejes med uret. Spolen drejes et
          par omgange, så båndoprulningen er sikret en korrekt begyndelse. 
          Til slut drejes nederste spole mod uret, hvorved båndet strammes
          op.

          Efter at båndet manuelt er strammet og kontrolleret for korrekt
          isætning i båndføringerne, skal båndet spoles frem, klar til
          drift. Det gøres som følger: 
           
          1.  Tænd for båndstationen med POWER kontakten. Om ønsket, kan
              båndstationen automatisk tændes/slukkes, når systemet
              tændes/slukkes, såfremt den ikke afbrydes med POWER kontakten
              under stopproceduren. 
           \f

          2.  Aktivr (tryk, slip) LOAD kontakten. Derved strammes båndet
              (capstan og spoledrivmotorer kobles ind og båndsløjfearmene
              svinger op). 
               
              Bemærk: Kontrollr at båndet er isat korrekt i alle båndfø-
                      ringer - båndet kan ellers beskadiges. 
           
          3.  Aktivr LOAD kontakten en gang til. Dermed startes fremspo-
              lingen af båndet. Når BOT mærket registreres af BOT/EOT
              føleren, stopper båndet og er nu i driftsposition. Igen bør
              båndet kontrolleres for korrekt styring i båndføringerne,
              hvorefter beskyttelseslågen lukkes. 
               
              Bemærk: Beskyttelseslågen bør være lukket så snart dele af
                      båndet er spolet over på øverste spole. Hvis ikke,
                      risikerer man, at forurening af båndet påvirker på-
                      lideligheden af dataoptegnelserne. 
               
           4. Vælg den korrekte kodningsmetode ved brug af HI DEN tryk-
                       kontakten. 
               
           5. Tryk på ON LINE kontakten. Når indikatoren lyser, er bånd-
              stationen klar til drift.

          1.  Pås, at båndstationen er off-line, dvs. ON LINE indikatoren
              er slukket. Ellers aktivr (tryk, slip) ON LINE kontakten,
              hvorved båndstationen kobles off-line. 
               
                       Bemærk: Båndstationen må kun kobles off-line, hvis båndet står
                      stille. 
                       
          2)  Aktivr (tryk, slip) REWIND kontakten. Båndet spoles derved
              tilbage og stoppes, når BOT mærket registreres - herefter
              indkobles en LOAD sekvens, der får båndet til at stille sig\f

              med BOT mærket ud for BOT/EOT føleren. Denne automatik er
              affødt af det >overløb>, der nødvendigvis sker, fordi et bånd
              ikke kan stoppes momentant. 
               
          3)  Aktivr REWIND kontakten en gang til. Dermed startes tilbage-
              spolingen påny og fortsættes indtil båndstramningen ophører.

          Efter at have udført stopproceduren, kan båndspolen tages ud,
          idet 
                    - beskyttelseslågen åbnes, 
                    - den frie båndende rulles manuelt op på nederste
                      spole, 
                    - udløseren på nederste spolenav trykkes ind og bånd-
                      spolen fjernes. 
           
          Hold altid beskyttelseslågen lukket, når båndstationen ikke
          betjenes. 
           
          Båndstationen afbrydes med POWER kontakten (jf. også 2.1.2 trin
          1).

          Press the push bar inwards to open the door. 
           
          Remove the diskette from the storage envelope. Make sure that the
          correct diskette side is facing upwards before loading. Usually
          the side with the label has to face upwards. However, in case a
          double-single-sided diskette is used either of the sides may have
          to be facing upwards, depending on the logical storage area which
          is to be used (cf. 3.4). 
           
          The diskette is carefully slid into the drive until solidly sea-
          ted. The diskette will then be kept properly in place in order
          that the door can be closed by pressing downwards on the front
          edge of the door.

          The diskette should only be unloaded when the activity indicator
          is extinguished. To remove the diskette the push bar is pressed
          inwards whereby the door is opened and the diskette is expelled
          from the drive. 
           
          The diskette should immediately be stored in the storage
          envelope.

          The diskette consists of a plastic disc which is contained in a
          disc cover. Do never attempt to remove the disc cover. Further
          the diskette is stored in an envelope. Storage envelopes should
          be replaced when they become worn in order that they provide
          maximum protection of the diskettes.

          Keep diskettes away from magnetic fields and from ferromagnetic
          materials which might become magnetized. Strong magnetic fields
          can distort recorded data on the disc. 
           
          Do not expose diskette to heat or sunlight, - storage temperature
          should be kept in the range 10 - 50C (50 - 125F). If the dis-
          kettes are stored vertically, support the diskettes in order that
          they do not lean or lag. 
           \f

                   Do not touch or attempt to clean the disc surface. The
          read-write head access the disc through the rectangular hole in
          the disc cover. 
           
          The diskettes are labelled with the manufactorer>s label to the
          left and with a label to the right stating the contents of the
          diskette. The latter can either be made by the user or the manu-
          factorer. 
           
          I_m_p_o_r_t_a_n_t_: 
          Never write on a diskette label after it has been stuck to the
          disc cover, - if doing so the disc surface migth be damaged. As
          an exception it can be done when using a felt tip pen.

                   It is automatically detected by the drive, whether a diskette is
          write-protected or not. 
           
          If a write-protected diskette have to be subjected to a write
          operation, this is possible by covering the notch with a piece of
          non-transparent tape. (The tape should be held against the disc
          cover edge and folded onto both sides of the cover). 
           
          When the notch is open the diskette is write-protected; when
          covered writing is enabled.

          There are 3 types of diskettes which are generally available for
          use with the drive. Which type of diskette that is used, is auto-
          matically detected by the drive. The operator only has to make
          sure that the correct diskette surface is facing upwards when
          loading the diskette.  
           
          Note: It is also possible that manufacturers> labels on the dis- 
                kettes can identify their types but this is not always
                obvious.  
           
          The types of diskettes are:  
           
          1) The single-sided diskette which has 1 recording surface and  
             is 1 logical disc storage area. 
           
                        It is identified by a small hole in its cover which
                        is at a position of approximately 12.15 o>clock
                        when holding the diskette vertically.  
           \f

                   2) The double-sided diskette which has 2 recording surfaces, one
             on each side, and is 1 logical disc storage area. 
           
                        It is identified by a small hole in its cover which
                        is at a position of approximately 1 o>clock when
                        holding the diskette vertically. 
                         
          3) The double-single-sided diskette which has 2 recording sur- 
             faces, one on each side, and is 2 logical disc storrage recor-
             ding surface. 
           
                        It is identified by 2 small holes in its cover
                        which are at positions of approximately 11.45 and
                        12.15 o>clock when holding the diskette vertically.
                         
             Note: The double-single-sided diskettes mainly are produced
             for equipment using only 1 read-write-head, thus the diskettes
             have to be flipped over in order to use both recording surfa-
             ces. This affects the way of formatting the diskette and
             despite the fact that other equipment uses 2 read-write heads
             (like the one at hand) such a pre-formatted double-single-
             sided diskette then still has to be flipped over.

          No direct operator maintenance is required at the drive; the  
          operator only has to meet the requirements involved with the
          disketette handling.

          Døren åbnes ved at trykke på udløseren. 
           
          Diskettens beskyttelseshylster fjernes. Sørg for, at den rigtige
          disketteside vender opad før isætningen. Normalt skal siden med
          etiketterne vende opad. I de tilfælde hvor en to-enkelt-sidet
          diskette anvendes, kan disketten vendes "rigtigt" med hver af
          siderne opad, det afhænger af den givne situation hvilken af de
          logiske lagerområder, der skal anvendes (jvf. 3.4). 
           
          Disketten skubbes forsigtigt ind til fast anslag i diskettesta-
          tionen. Ved korrekt isætning bliver disketten nu liggende i
          stationen, således at døren kan lukkes ved at trykke ned på
          dørens forkant.

          Disketten må kun tages ud af diskettetstationen, når driftsindi-

          en, hvorved døren åbnes og disketten springer frem i åbningen. 
           
          Disketten skal umiddelbart efter brug anbringes i beskyttelses-
          hylsteret.

          En diskette består af en plastskive omsluttet af et pladehylster,
          der i_k_k_e_ må forsøges fjernet. Desuden opbevares disketten i et
          beskyttelseshylster. Beskyttelseshylstrene bør udskiftes, når
          disse er slidt, for til stadighed at yde den bedste beskyttelse.

          Under opbevaring af disketter skal man påse, at disketterne ikke
          udsættes for påvirkning fra magnetiske felter, idet dataoptegnel-
          serne i så fald kan blive forvansket. 
           
          Undgå ligeledes at udsætte disketter for direkte sollys, - opbe-
          varingstemperaturen skal være 10 - 50C. Opbevares disketterne
          "stående", skal de understøttes for at undgå eventuelle skævheder
          i disketten, der ellers måtte opstå. 
           
          Plastskiven må ikke berøres, ligesom den ikke må udsættes for
          forsøg på rensning. Læse-skrive-hovedet har adgang til plastski-
          ven gennem det aflange hul i pladehylsteret. 
           \f

                   Mærkning af disketter sker med selvklæbende etiketter. Normalt
          findes en firmaetiket i venstre hjørne. Ved siden af denne sidder
          en etiket med oplysninger om diskettens indhold, enten påsat af
          bruger eller leverandør. 
           
          V_i_g_t_i_g_t_: 
          Hvis en bruger selv ønsker at mærke sine disketter, er det vig-
          tigt IKKE at skrive på etiketten, efter at denne er påsat plade-
          hylsteret,- i så fald vil man nemt kunne beskadige diskettens
          overflade. Undtagelsesvis kan det gøres, men da kun med en filt-
          pen.

          Ønskes en diskette beskyttet mod indlæsning af data, kan et hak
          udstandses. 
           
           
           
           
           
           
           
           
           
           
           
           
           
           
           
           
           
           
           
           
           
           
          Figur 4: Udstandsning til beskyttelse mod indlæsning, placering \f

                   Diskettestationen registrerer automatisk, om en diskette er be-
          skyttet mod indlæsning eller ej. 
           
          Når en beskyttet diskette på et senere tidspunkt skal have ind-
          læst eller ændret data, kan dette gøres, hvis udstandsningen
          overklæbes med et stykke ikke-gennemsigtigt tape. (Hold tapen mod
          kanten og fold ind over begge sider). 
           
          Når udstandsningen på denne måde lukkes, er indlæsning altså
          mulig - modsvarende en åben udstandsning, da er indlæsning ikke
          mulig.

          Der skelnes mellem 3 diskettetyper. De kan alle bruges, idet dis-
          kettestationen automatisk registrerer, hvilken type diskette, der
          er isat. Blot skal operatøren selv huske, at disketten vendes
          rigtigt; specielt den to-enkelt-sidet diskette kan vende "rig-
          tigt" på flere måder afhængig af situationen. 
           
          Bemærk: Normalt angives diskettetypen også på firmaetiketten, men
                  reglerne herfor er ikke helt entydige. 
           
          De 3 diskettetyper er: 
           
          1) enkelt-sidet, 
             disketten har 1 lagerflade og udgør 1 logisk lagerområde. 
              
                          I_d_e_n_t_i_f_i_k_a_t_i_o_n_: holdes disketten lodret med eti-
                          ketterne opad, ses i pladehylsteret under etiket-
                          terne et hul cirka i positionen "klokken 12.15". 
                           \f

          2) dobbelt-sidet, 
             disketten har 2 lagerflader, en på hver side, men udgør 1
             logisk lagerområde. 
              
                          I_d_e_n_t_i_f_i_k_a_t_i_o_n_: holdes disketten lodret med eti-
                          ketterne opad, ses i pladehylsteret under etiket-
                          terne et hul cirka i positionen "klokken 13.00". 
                           
                   3) to-enkelt-sidet, 
             disketten har 2 lagerflader, en på hver side, og udgør 2
             logiske lagerområder. 1 logisk lagerområde bruges ad gangen og
             disketten vendes, når der skal skiftes til det andet logiske
             område. 
              
                          I_d_e_n_t_i_f_i_k_a_t_i_o_n_: holdes disketten lodret med
                          etiketterne opad, ses i pladehylsteret under
                          etiketterne to huller cirka i positionerne
                          "klokken 11.45 og 12.15". 
                           
             Bemærk: to-enkelt-sidet disketter fremstilles primært af
                      hensyn til udstyr, der kun benytter 1 læse-skrive-hoved. 
             Disketten skal derfor vendes for at kunne udnyttes på begge
             lagerflader. Dette indvirker på formatteringen og trods det
             forhold, at andre typer af udstyr (som det nærværende) benyt-
             ter 2 læse-skrive-hoveder, skal en sådan pre-formatteret
             to-enkelt-sidet diskette altså vendes.

          Operatøren har ingen direkte vedligeholdelsesopgaver i relation
          til diskettestationen, men skal følge forskrifterne for disket-
          tens behandling og opbevaring.
