Figure 1: The matrix printer. 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). \f 2_._ _ _ _ _ _ _ _ _O_P_E_R_A_T_I_N_G_ _C_O_N_T_R_O_L_S_ 2. The below description points at the various controls attended by the operator. The actual procedures in operating are described later on. 2_._1_ _ _ _ _ _ _ _C_o_n_t_r_o_l_ _P_a_n_e_l_ 2.1 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). 2_._2_ _ _ _ _ _ _ _P_r_i_n_t_ _M_o_d_u_l_e_ 2.2 Figure 3: Print module. 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 Figure 4: Margin indicators. 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 marked on top of the printhead, - 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. Figure 5: Index marks, paper adjustment. The paper form is positioned to either of the two vertical position marks by pulling out the paper adjustment knob and turning it. \f 2_._3_ _ _ _ _ _ _ _P_a_p_e_r_ _T_r_a_n_s_p_o_r_t_ _U_n_i_t_ 2.3 The paper transport unit is tilted by pulling upwards as shown. The paper trans- port is performed by two tractors, one to the left and one to the rigth. Figure 6: Paper transport, tractors. The tractors can be in slid the sidewards direction when relea- sing the locking arms. Figure 7: Paper tractor, positioning. \f 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.

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. \f 3_._2_ _ _ _ _ _ _ _L_o_a_d_i_n_g_ _t_h_e_ _V_F_U_ _T_a_p_e_ 3.2 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. 3_._3_ _ _ _ _ _ _ _L_o_a_d_i_n_g_ _t_h_e_ _P_a_p_e_r_ _F_o_r_m_ 3.3 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. \f 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- wards when entering the paper. Printing side Paper is loaded on the tractors by opening the holding flaps, inserting the paper on the sprocket belt and lowering the flaps. It Print lines horizon- may be necessary coarsly tally when paper is to adjust the tractors loaded. in order to accommodate the paper forms width. The paper transport unit is til- ted towards the printer front and paper is loaded to the tractors on the bottom side. No slope allowed. \f 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- tion with the left-hand 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. 3_._4_ _ _ _ _ _ _ _P_r_i_n_t_e_r_ _A_d_j_u_s_t_m_e_n_t_s_ 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 3_._4_._1_ _ _ _ _ _M_a_r_g_i_n_ _S_e_t_t_i_n_g_s_ With the print module in the service posi- tion, slide the left-hand margin indicator up to the left-hand stop. The rigth- hand indicator should be posi- tioned in order that printing is n_e_v_e_r_ allowed outside the paper form. 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. 3_._4_._2_ _ _ _ _ _V_e_r_t_i_c_a_l_ _P_r_i_n_t_ _P_o_s_i_t_i_o_n_i_n_g_ 3.4.2 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. 3_._5_ _ _ _ _ _ _ _A_l_a_r_m_s_ 3.5 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. \f F_ 4_._ _ _ _ _ _ _ _ _S_U_P_P_L_E_M_E_N_T_A_R_Y_ _N_O_T_E_S_ 4. 4_._1_ _ _ _ _ _ _ _I_n_s_t_a_l_l_a_t_i_o_n_ 4.1 When installing the printer, use the following check points: . solid disk, minimum height 60 cm . felt pad under printer . paper path free of obstacles . ample space behind the printer . correct mounting of paper spreader (grille - casing pivots) and paper deflector (yoke - cooling air slit). Note: Also the paper deflector must be out off the edge of the table. . mains voltage selector . mains power cord . data cable \f Also check release of transport locking arms and other transport safety arrangements. Inside the printer cover at both sides of the print module a transport lock is found. They are unlocked by pressing towards the printer front, til- ting the printer module and al- lowing the locking arms to turn towards the printer rear. Whenever the printer is trans- ported, the locking arms should be re-engaged. 4_._2_ _ _ _ _ _ _ _V_F_U_ _T_a_p_e_ 4.2 The VFU tape is a standard 8 channel mylar (or n_o_n_t_r_a_n_s_p_a_r_e_n_t_ plastic) tape, containing 10 division lines per inch for hole punching. The tape must have sprocket feed holes in the full tape length. L_i_n_e_ _F_e_e_d_ _H_o_l_e_s_ _(_L_F_H_)_ A hole is punched in channel 4 corresponding to each line on the paper form (regardless of being a line for printing or not). If there are to be 6 lines per inch on the paper form, each position on the tape is punched; at 3 lines per inch only each second position is punched. V_e_r_t_i_c_a_l_ _T_a_b_u_l_a_t_o_r_ _S_t_o_p_s_ _(_V_T_S_)_ A hole is punched in channel 5 corresponding to each vertical stop position. \f T_o_p_ _O_f_ _F_o_r_m_ _(_T_O_F_)_ A hole is punched in channel 6 corresponding to the first line to be printed on the paper form. E_n_d_ _o_f_ _F_o_r_m_ _(_E_O_F_)_ A hole is punched in channel 7 corresponding to the last line to be printed on the form. The EOF punching always m_u_s_t_ be present. 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. Tape spacing accuracy requirements in channel 4 (LFH-channel) are: 3% - 1 spacing; 1% - 10 spacings; 0.5% - 50 spacings. 4_._2_._1_ _ _ _ _ _P_r_o_g_r_a_m_m_i_n_g_ 4.2.1 The holes are punched using a hand-operated punch (available as printer accessory). Figure 11: Minipunch (5 or 8 channels). \f A paper form could look like this: The corresponding VFU tape would look like this: \f 4_._2_._2_ _ _ _ _ _S_p_l_i_c_i_n_g_ 4.2.2 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.

Upon insertion of new spools observe that the spools must engage the taps. The ribbon is run in the path shown. After loading, ascertain that the ribbon runs cor- rectly in the guide 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.

From below the platen it can be pulled through in order to be loaded on the tractors. The printing side has to face down- wards when entering the paper. Printing side Paper is loaded on the tractors by opening the holding flaps, inserting the paper on the sprocket belt and lowering the flaps. It Print lines horizon- may be necessary coarsly tally when paper is to adjust the tractors loaded. in order to accommodate the paper forms width. The paper transport unit is til- ted towards the printer front and paper is loaded to the tractors on the bottom side. No slope allowed. \f 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- tion with the left-hand 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. 3_._4_ _ _ _ _ _ _ _P_r_i_n_t_e_r_ _A_d_j_u_s_t_m_e_n_t_s_ 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 3_._4_._1_ _ _ _ _ _M_a_r_g_i_n_ _S_e_t_t_i_n_g_s_ With the print module in the service posi- tion, slide the left-hand margin indicator up to the left-hand stop. The rigth- hand indicator should be posi- tioned in order that printing is n_e_v_e_r_ allowed outside the paper form. 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. 3_._4_._2_ _ _ _ _ _V_e_r_t_i_c_a_l_ _P_r_i_n_t_ _P_o_s_i_t_i_o_n_i_n_g_ 3.4.2 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. 3_._5_ _ _ _ _ _ _ _A_l_a_r_m_s_ 3.5 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. \f F_ 4_._ _ _ _ _ _ _ _ _S_U_P_P_L_E_M_E_N_T_A_R_Y_ _N_O_T_E_S_ 4. 4_._1_ _ _ _ _ _ _ _I_n_s_t_a_l_l_a_t_i_o_n_ 4.1 When installing the printer, use the following check points: . solid disk, minimum height 60 cm . felt pad under printer . paper path free of obstacles . ample space behind the printer . correct mounting of paper spreader (grille - casing pivots) and paper deflector (yoke - cooling air slit). Note: Also the paper deflector must be out off the edge of the table. . mains voltage selector . mains power cord . data cable \f Also check release of transport locking arms and other transport safety arrangements. Inside the printer cover at both sides of the print module a transport lock is found. They are unlocked by pressing towards the printer front, til- ting the printer module and al- lowing the locking arms to turn towards the printer rear. Whenever the printer is trans- ported, the locking arms should be re-engaged. 4_._2_ _ _ _ _ _ _ _V_F_U_ _T_a_p_e_ 4.2 The VFU tape is a standard 8 channel mylar (or n_o_n_t_r_a_n_s_p_a_r_e_n_t_ plastic) tape, containing 10 division lines per inch for hole punching.

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.

Figur 1: Matrixprinteren. 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). \f F_ 2_._ _ _ _ _ _ _ _ _B_E_T_J_E_N_I_N_G_ 2. I det følgende beskrives de forskellige funktioner, som operatør- en skal betjene. En egentlig vejledning i betjening følger sene- re. 2_._1_ _ _ _ _ _ _ _B_e_t_j_e_n_i_n_g_s_p_a_n_e_l_ 2.1 Figur 2: Betjeningspanel. 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 kontakt printeren modtage data til udskrivning. 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- toren). \f 2) PAPER LF/TOF - når kontakten trykkes i LF stil- kontakt ling og hurtigt slippes igen, føres papiret en linie frem. (LF = L_ine F_eed = ny linie) Når kontakten trykkes i LF stilling og holdes der, føres (TOF = T_op O_f F_orm papiret frem, indtil kontakten = 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. 3) EOP - denne indikator tændes umiddel- 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 aktivering. \f Advarselssignal - tonesignalet anvendes desuden, når der modtages et BELL kode- tegn, eller når der opstår funk- tionsfejl. Et BELL signal varer ca. 1 sek. og bruges oftest, når der sendes en meddelelse til udskrivning på printeren. Andre advarselssignaler kan ikke umiddelbart annulleres, undtagen når der slukkes med hovedafbryd- eren. (Se omtale senere). 2_._2_ _ _ _ _ _ _ _S_k_r_i_v_e_m_o_d_u_l_ 2.2 Figur 3: Skrivemodul Skrivemodulet frigøres ved at trække de to låsearme udefter som vist. Modulet svinger af sig selv op i servicestilling (fjeder- belastet). Når modulet er i servicestilling, kan margenindikatorerne ind- stilles. \f Figur 4: Margenindikatorer. Skrivehovedet s_k_a_l_ _a_l_t_i_d_ befinde sig mellem de to margenindika- torer. Margenindstillingen ændres ved at skubbe indikatoren langs ad skalaen. Højre margin skal indstilles, så der ikke skrives udenfor papiret. Til brug ved finindstilling af papiret findes 3 indekseringsmær- ker: - den horisontale skriveposition er vist ovenpå skrivehovedet, - den vertikale position for udskrivning af en linie indi- keres på højre side af skrive- hovedet, - et referancemærke er angivet på venstre papirfremførings- enhed; det angiver en afstand på 15 linier til den vertikale position for udskrivning af en linie. Figur 5: Indekseringsmærker. \f Papiret indstilles i forhold til et af de to vertikale positio- neringsmærker, idet indstillingshåndtaget trækkes ud og drejes. 2_._3_ _ _ _ _ _ _ _P_a_p_i_r_t_r_a_n_s_p_o_r_t_ 2.3 Papirfremføringsenheden vippes op som vist. Papir- transporten besørges af en højre og en venstre fremfø- ringsenhed. Figur 6: Papirfremføring. Hver af fremføringsenhederne kan flyttes i sideværts retning, når låsearmen frigøres. Figur 7: Fremføringsenhed, indstilling. \f Hver fremføringsenhed har fire holdeplader, to på oversiden og to på undersiden. Med disse holdeplader sikres, at papiret er i indgreb med fremføringsbæltet.

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. \f 3_._2_ _ _ _ _ _ _ _I_s_æ_t_n_i_n_g_ _a_f_ _V_F_U_ _s_t_r_i_m_m_e_l_ 3.2 Strimlen gøres klar ifølge pkt. 4.2. LINE kontakten skal stilles i OFF stilling. Overdelen åbnes og tilholderhåndtaget på VFU enheden åbnes. Strimlen isættes, så- ledes at fremføringshullerne (de mindste huller) går i indgreb med fremføringshjulet og så- ledes at strimlens øvrige hul- ninger vender ind mod printer- en. Tilholderhåndtaget slås ned igen til lukket stilling. Kon- trollr, om strimlen er korrekt isat. Efter isætning af en VFU strimmel, er det nødvendigt at indstille papirfremføringen som beskrevet i pkt. 3.4.2. 3_._3_ _ _ _ _ _ _ _I_s_æ_t_n_i_n_g_ _a_f_ _p_a_p_i_r_ 3.3 LINE kontakten skal stilles i OFF stilling. Overdelen åbnes, skrivemodulet frigøres og vippes i service- stilling. Papirfrem- føringsenhederne vippes op i en stilling med cirka 45 baglæns hæld- ning. \f Papiret føres ind bagfra og skub- bes frem. Papiret gribes under skrivevalsen og trækkes frem til isætning i fremføringsenhederne. Skrivesiden skal vende nedad, når papiret føres ind i printeren. Skrivesiden. Papiret isættes, idet holdepladerne på frem- føringsenhedernes over- side åbnes, papirets fremføringshuller føres til indgreb med bæltet og holdepladerne lukkes nedover papiret. Det kan være nødvendigt at Linierne skal være forindstille fremføringsenhederne, vandret efter isæt- så deres positioner cirka svarer ning. til papirbredden. Fremføringsenhederne vippes nu forover og papiret isættes tilsvarende på undersiden. Papirsløjfe ikke tilladt. \f Fremføringsenhederne vippes tilbage til driftsstilling - papiret trækkes samtidig bagud, så det ikke krølles. Venstre fremføringsenhed stilles derefter overensstemmende med venstre margenposition og låses. Højre fremføringsenheden trækkes let mod højre, idet den låses, således at papiret strammes i tværretningen. 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. 3_._4_ _ _ _ _ _ _ _I_n_d_s_t_i_l_l_i_n_g_ _a_f_ _p_r_i_n_t_e_r_ 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. \f 3_._4_._1_ _ _ _ _ _I_n_d_s_t_i_l_l_i_n_g_ _a_f_ _m_a_r_g_e_n_s_t_o_p_ 3.4.1 Med skrivemodulet vip- pet op i servicestil- ling, kan venstre mar- genindikator skubbes helt ud mod venstre endestop. Højre margen- indikator stilles så- ledes, at der a_l_d_r_i_g_ skrives uden for pa- pirbredden. Bemærk: Skrivehovedet kan ikke arbejde uden for margenpositio- nerne. Hvis linielængden ikke svarer til margenindstil- lingen, vil de overskydende tegn blive udskrevet på næste line, hvorved der sker en forskydning af formatopbyg- ningen som ødelægger den programmerede vertikale format- styring. Skrivemodulet vippes tilbage til arbejdsstilling. Skrive- hovedet flyttes ud til ventre marginposition ved 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. 3_._4_._2_ _ _ _ _ _I_n_d_s_t_i_l_l_i_n_g_ _a_f_ _v_e_r_t_i_k_a_l_ _s_k_r_i_v_e_p_o_s_i_t_i_o_n_ 3.4.2 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- les afrivningslinien lige udfor mærket. Stadig med håndtaget trukket ud, aktiveres nu PAPER TOF kontakten. Håndtaget kan så slippes. \f 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. 3_._5_ _ _ _ _ _ _ _A_d_v_a_r_s_e_l_s_s_i_g_n_a_l_e_r_ 3.5 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.

Figur 1: Betjeningspanel. 1) POWER - når kontakten trykkes ind kontakt/indikator og indikatoren tændes, er der tændt for magnetbånd- stationen. 2) LOAD - når kontakten trykkes ind kontakt/indikator og indikatoren tændes, påbegyndes LOAD sekven- sen. Første gang kontakten aktiveres vil båndet blive strammet op. Næste aktivering vil be- virke, at båndet spoles frem til BOT mærket og\f stoppes. (BOT = markering af båndets begyndelse; EOT = markering af båndets slutning). 3) ON LINE - når kontakten trykkes ind kontakt/indikator og indikatoren tændes, kobles båndstationen on-line. Kontakten virker kun efter en forudgående LOAD, eller REWIND, sekvens. Næste aktivering af kon- takten vil bevirke, at båndstationen kobles off- line. Båndstationen kan også kobles off-line som følge af en ordre fra systemet, eller på grund af svigtende båndstram- ning. 4) REWIND - når kontakten trykkes ind kontakt/indikator og indikatoren tændes, vil båndet spoles tilbage med højeste hastighed. Denne funktion virker kun, når båndstationen er koblet off-line. Når BOT-mærket registre- res, stoppes tilbagespo- lingen og båndstationen påbegynder en LOAD sekvens. \f REWIND indikatoren for- bliver tændt også under den påfølgende LOAD sekvens. 5) WRT EN (W_r_it_e e_n_able) - indikatoren tændes, når indikator der monteres en båndspole med en skrivering. Når denne ring er mon- teret, kan der både >skrives> og >læses> på båndet - uden denne ring, kan der kun >læses>. 6) HI DEN (H_igh d_e_n_sity) - når kontakten trykkes ind kontakt/indikator og indikatoren tændes, vælges kodningsmetoden med den største bittæthed (PE/1600 bpi). Når kontakten aktiveres, så indikatoren slukkes ("hver anden gang" kon- takten aktiveres), vælges kodningsmetoden med den mindste bittæthed (NRZI/800 bpi). 7) FORWARD - når kontakten trykkes ind kontakt/indikator og indikatoren tændes, spoles båndet frem med normal driftshastighed. Denne funktion virker kun, når båndstationen er koblet off-line. \f Når kontakten aktiveres en gang til, stoppes båndet. 8) REVERSE - spoler båndet baglæns med kontakt/indikator normal driftshastighed, virker ellers som FORWARD. \f F_ 2_._ _ _ _ _ _ _ _ _B_E_T_J_E_N_I_N_G_S_V_E_J_L_E_D_N_I_N_G_ 2. 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. 2_._1_ _ _ _ _ _ _ _I_s_æ_t_n_i_n_g_ _a_f_ _b_å_n_d_ 2.1 2_._1_._1_ _ _ _ _ _M_o_n_t_e_r_i_n_g_ _a_f_ _b_å_n_d_s_p_o_l_e_ 2.1.1 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. \f 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. 2_._1_._2_ _ _ _ _ _S_t_a_r_t_p_r_o_c_e_d_u_r_e_ 2.1.2 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. 2_._2_ _ _ _ _ _ _ _U_d_t_a_g_n_i_n_g_ _a_f_ _b_å_n_d_ 2.2 2_._2_._1_ _ _ _ _ _S_t_o_p_p_r_o_c_e_d_u_r_e_ 2.2.1 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. 2_._2_._2_ _ _ _ _ _U_d_t_a_g_n_i_n_g_ _a_f_ _b_å_n_d_s_p_o_l_e_ 2.2.2 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.

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. Figure 3: Diskette and Storage Envelope 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.

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. 3_._3_ _ _ _ _ _ _ _T_y_p_e_s_ _o_f_ _D_i_s_k_e_t_t_e_s_ 3.3 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. 3_._4_ _ _ _ _ _ _ _M_a_i_n_t_e_n_a_n_c_e_ 3.4 No direct operator maintenance is required at the drive; the operator only has to meet the requirements involved with the disketette handling. \f i I_N_D_H_O_L_D_S_F_O_R_T_E_G_N_E_L_S_E_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _S_I_D_E_ _ 1.

Skal disketten tages ud, trykkes på udløser- en, hvorved døren åbnes og disketten springer frem i åbningen. Disketten skal umiddelbart efter brug anbringes i beskyttelses- hylsteret. \f 3_._ _ _ _ _ _ _ _ _S_U_P_P_L_E_R_E_N_D_E_ _I_N_F_O_R_M_A_T_I_O_N_ 3. 3_._1_ _ _ _ _ _ _ _B_e_h_a_n_d_l_i_n_g_ _a_f_ _d_i_s_k_e_t_t_e_r_ 3.1 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. Figur 3: Diskette med beskyttelseshylster. 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. 3_._2_ _ _ _ _ _ _ _B_e_s_k_y_t_t_e_l_s_e_ _a_f_ _d_i_s_k_e_t_t_e_r_ _m_o_d_ _i_n_d_l_æ_s_n_i_n_g_ _(_w_r_i_t_e_-_p_r_o_t_e_c_t_)_ 3.2 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. 3_._3_ _ _ _ _ _ _ _D_i_s_k_e_t_t_e_t_y_p_e_r_ 3.3 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. 3_._4_ _ _ _ _ _ _ _V_e_d_l_i_g_e_h_o_l_d_e_l_s_e_ 3.4 Operatøren har ingen direkte vedligeholdelsesopgaver i relation til diskettestationen, men skal følge forskrifterne for disket- tens behandling og opbevaring. \f F_i_g_u_r_t_e_k_s_t_ _t_i_l_ _R_C_S_L_ _4_1_-_i_1_5_1_4_: Figur 1: 1) dør 2) udløser 3) driftsindikator Figur 3: firmaetiket diskette plastskive, M_Å_ _I_K_K_E_ _B_E_R_Ø_R_E_S_ beskyttelseshylster hold på disketten her etiket med oplysning om diskettens indhold Figur 4: udstandsning til beskyttelse mod indlæsning \f «eof»
