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).

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).

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.

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.

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.
\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.

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).

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.
Figure 12: Splicing. \f

The ribbon spools are released
for replacement by pressing the
levers downwards. 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. Should ribbons other
than the recommended be used, these must be fitted with the
rivets mentioned.

from position of printed line is
found at left-hand tractor.

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.

sing the locking arms.
Figure 7: Paper tractor, positioning. \f
Each tractor has four paper hol-
ding flaps, two on top and two

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.

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.

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.

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 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

\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.

The ribbon spools are released
for replacement by pressing the
levers downwards. 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. Should ribbons other
than the recommended be used, these must be fitted with the
rivets mentioned.

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.

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).

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

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

enhed; det angiver en afstand
på 15 linier til den vertikale
position for udskrivning af en
linie.

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.

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.

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.

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

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.

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.

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.

. underlag under printer
. papirtilgang og -afgang
fri for forhindringer
. rigelig plads bagved

Kontrollr også om transportsikringsudstyret er frigjort, hen-
holdsvis fjernet.
På begge sider af skrivemodulet
er anbragt en transportlås.
Låsen frigøres, idet låsearmen
vippes mod printerens front,
skrivemodulet vippes op og
låsearmen vippes helt bagover.
Disse to låse skal benyttes under
enhver transport af printeren.

VFU strimlen er en standard 8-kanal mylar (eller anden u_g_e_m_m_e_m_-
s_i_g_t_i_g_ plast) strimmel med 10 delinger pr. tomme. Strimlen
skal være forsynet med fremføringshuller i hele sin længde.

Der hulles et hul i kanal 4 svarende til hver linie på papiret
(uanset om linien benyttes til udskrivning eller ej). Hvis der
arbejdes med 6 linier per tomme på papiret, skal der hulles i
alle strimmelpositioner; arbejdes der med 3 linier per tomme,
skal der hulles i hveranden strimmelposition.

holdt i programmeringen.
Strimmellængden efter splejsning skal være mellem 75-160
hulninger (kanal 4). Ellers må det korte program gentages et
antal gange, således at den krævede længde opnås.
Der kræves en delingsnøjagtighed med hensyn til kanal 4 hulninger
(LFH kanal) på: 3% - 1 deling; 1% - 10 delinger; 0,5% - 50 de-
linger.

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.

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

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.
\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.

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.

POWER ON/OFF - power is supplied automa-
(not shown) tically to the drive
through the system power
supply.
At the rear panel of the
drive there is a mains
power switch, which can
be used in those cases
where the drive has to be
isolated from the general
system power supply.
1) Door - the door is opened by
pressing the push bar
inwards. It is closed by
pressing downwards on the
front edge.
2) Push Bar - when pressed inwards this
opens the door. \f
3) Activity indicator - this ligth emitting diode
(LED) mounted in the push
bar on the front is illu-
minated whenever the
read-write head is loa-
ded.
Note: The ligth emitting
diode may be mounted away
from the push bar to the
left on the front on some
models.

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.
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. As
an exception it can be done when using a felt tip pen.

To write-protect a diskette a notch must be punched out.
Figure 4: Position of Write-protect Notch \f
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.
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.

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

POWER ON/OFF - diskettestationen for-
(ikke vist) synes automatisk med
strøm via systemet.
På diskettestationens
bagpanel findes en hoved-
afbryder, der kan bruges
i de tilfælde, hvor sta-
tionen ønskes frakoblet
strømforsyningen.
1) dør - døren åbnes ved at trykke
på udløseren. Døren luk-
kes ved at trykke nedad
på dørens forkant.
2) udløser - tryk ind og døren åbnes. \f
3) driftsindikator - denne lysindikator er
indbygget i udløseren og
lyser, når læse-skrive-
hovedet er aktiveret,
dvs. når diskettesta-
tionen arbejder.
NB: indikatoren er på
nogle modeller placeret
til venstre på frontpa-
nelet og ikke i udløser-
en.

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.

Beskyttelseshylsteret skal opbevares så tilsmudsning undgås, mens
disketten bruges. \f
2_._2_ _ _ _ _ _ _ _U_d_t_a_g_n_i_n_g_ 2.2
Disketten må kun tages ud af diskettetstationen, når driftsindi-
katoren er slukket. 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.

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.

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.

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