ORGANIZATION OF THIS MANUAL

This manual is divided into 9 chapters. Use chapters 1 through 3 as a “User

Guide”, giving you information on how to set up and start your printer. The
remaining chapters may be treated as a reference guide for programming
operations, etc. It assumes a degree of knowledge off the operation of
computers (for instance, it assumes you know about hexadecimal numbers).

The chapters am as follows:

Chapter 1 - Introduction

Read this section first, as it explains how to unpack and install your printer.

Chapter 2 - Front panel controls

There are a number of controls on the front panel which perform various

functions related to paper handling, print modes and font selection. This
section shows you how to use the front panel controls.

Chapter 3 - Setting up the Memory Switches

Your printer has a Memory Switch function, which allows you to make
certain system settings from the front panel. This section explains the
operation of these Memory Swithes.

Chapter 4 - Emulations and escape codes

This chapter explains the different emulations provided by your printer, and
the software commands used to drive it. This section is of use if you am
writing or modifying programs to take advantage of the printer’s features.

Chapter 5 - DIP Switches

This section explains how to set the DIP switches to make system settings
on the printer.

Chapter 6 - MS-DOS and your printer

Since the PC or PC-AT family of computers running under MS-DOS is
currently the most popular configuration of microcomputer, we have in­cluded a few hints and tips to help you use your printer with such systems.
Since virtually all PCs are sold with a Microsoft BASIC interpreter, we have
also included some hints, and a sample program in this language to
demonstrate the capabilities of the printer.

Chapter 7 - Troubleshooting and maintenance

This section give a checklist of points to check if your printer is not working
in the expected way. It also includes details of some routine maintenance
operations you can carry out yourself. It is not, however, a complete service
manual. Call a qualified service engineer if you am unsure of your ability to
carry out any maintenance or servicing operations.

Chapter 8 - Specifications

This section gives the specifications of your printer.

chapter 1

INTRODUCTION

The following section covers the unpacking and installation of your printer,
together with information on paper loading and handling (both continuous
and cut-sheet paper).

LOCATING THE PRINTER

Before you start unpacking and setting up your printer, make sure that you
have a suitable place on which to locate it. By “a suitable place”, we mean:

l A firm, level surface which is fairly vibration-free
l Away from excessive heat (ie away from direct sunlight and away from

heaters, etc)

l Away from excessive humidity
l Away from excessive dust
l A location with sufficient space to locate the printer and any paper to be

fed into it, as well as the printed paper coming out

l If you are using a parallel connection to your computer, make sure that it

is within 2m (6ft) of the printer (an RS-232 connection using the optional
RS-232 interface can be made over longer distances).

UNPACKING, SETTING UP AND CONNECTION

Now unpack the contents of the printer shipping container, and make sure
that you have the following:

l The printer itself

9 Paper guide assembly

l The platen knob
l A fabric ribbon

If any of these items are missing, contact your supplier.

1

The optional accessories which you may have ordered with your printer are:

l Serial (RS-232) interface board
l Automatic sheet feeder
l Color option kit

See the installation instructions contained with these optional items for
details of how to attach them to your printer.

2

Setting up

Place your printer in the position where it is going to be permanently sited,
and remove all packing material from inside the top cover. This packing
material is intended to prevent damage to the printer in transit. You may like
to keep this packing with the printer carton if you intend transporting the
printer for use at a different location.

laten

knob

The platen knob should be removed from the accessory box inside the

shipping carton. Mount the platen knob on the shaft on the right-hand side
of the printer. Turn the knob on the shaft before pushing the knob fully into

position.

NOTE

Before turning the platen knob, always ensure that the power to the printer

is OFF. Turning the platen knob when the power is on can damage the

printer’s gears.

3

Remove the top cover by lifting the front (using the two grips at the side),
and pulling towards you. Now install the ribbon.

1 Use the tensioning knob on the ribbon cartridge to tighten the ribbon if it

is slack (turn clockwise).

2 The ribbon should pass between the print head and the print head shield

(see illustration below).

Print head shield

Ink ribbon

3 Use the grips on the side of the ribbon cartridge to help locate the cartridge

(squeeze them inwards gently), and make sure that the spindles on the
cartridge holder fit into the sockets on the cartridge itself.

Connection

Connect the printer to your computer, using a standard parallel-type cable.

On a PC or PC/AT-type computer, this means that you use the 25-way D­type connector at the computerend, and the Amphenol-type 36-way connec­tor at the printer end. The pinouts of the printer’s connector are given in

Chapter 8 if you need a cable for connection to another computer.
Plug the printer into a suitable mains outlet. However, DO NOT turn on the
power switch at the back of the printer yet.

5

You may need to set some DIP switches inside the printer before you start
using it. These switches enable you to configure the printer as an Epson or
as an IBM Proprinter printer. The DIP switches also enable you to select a
character set other than the USA character set, if your supplier has not
already set these up for you. The DIP switch cover is located inside the top
cover (see below). Use the end of a paper-clip (or similar) to set the switches.
Details of these switches are given in Chapter 5. If you feel unsure as to your
ability to set these switches, contact your supplier.

LOADING PAPER

The following sections explain how to load paper - single-sheet (cut-sheet),
without the Automatic Sheet feeder, and also the operations necessary for

loading continuous (fanfold) stationery.
If you are using the Automatic Sheet Feeder, please refer to the instructions
supplied with the Automatic Sheet Feeder unit.

Cut-sheet paper

Place the paper guide in position, locating the lugs on the bottom of the

assembly into the slots on the printer body.

Make sure that the release lever is pushed towards the back of the printer

( h position).

Adjust the paper guides to match the size of paper you will be using (re­membering that printing will start some distance from the left-hand edge
of the carriage). There are markings molded into the back plate of the

assembly to help you if you wish to center the paper. If you are centering
the paper using the markings molded into the paper guide, remember that
printing will start from the left-hand edge, unless you reset the left and
right margins using software commands.

4

Place the paper between the guides, placing the side on which you want
to print towards the back of the printer. Gently push the paper down in the
guides until you feel it stop.

Adjustable paper guides

5 Turn on the power using the switch at the back of the printer. The printer

will beep, indicating that no paper is in position for printing. The orange
PAPER indicator also shows this.

6 Now press the m button. The paper bail will move clear of the paper,

and the paper will be fed and adjusted past the print head to a position
ready for printing. The paper bail will be moved back to grip the paper
against the platen, and the print head will move to the start position.

The actual vertical position of the paper after auto-loading is determined by
the Memory Switch setting (see Chapter 3).
The vertical position of the paper can be finely adjusted by means of the
micro feed function (see Chapter 2).

Fanfold paper (continuous) stationery

If you are going to use fanfold (continuous) paper, then you will need to use
the integral tractor mechanism assembly, situated under the rear cover of the
printer.

1 Remove the top and rear covers of the printer to insert the paper.

2 Push the release lever towards the front of the printer (to the m position).

This has the effect of releasing the paper from the platen roller, and

engaging the tractor feed.

3 With the sprocket covers open, thread the paper over the sprockets,

aligning the sprocket holes with the pins on the sprockets.

4 Adjust the spacing of the sprockets by sliding them along the bar, using

the clamp lever at the back of each sprocket to release and lock the

sprocket in position (when the lever is up, the sprocket may be moved, and
when it is down, the sprocket is locked).

5 Now close the sprocket covers, again making sure that the paper sprocket

holes are aligned with the pins on the sprockets. If they are not aligned

properly, you, will have problems with paper feeding, possibly resulting

in tearing and jamming of the paper.

6 Turn on the printer using the switch at the back of the printer. The printer

will beep (indicating that the paper is not yet fully loaded). This is also

confirmed by the orange PAPER indicator.

9

7 Now press the C

=V~?ET j button. The paper bail will move clear of the paper,
and the paper will be fed and adjusted past the print head to a position
ready for printing. The paper bail will be moved back to grip the paper
against the platen, and the print head will move to the start position. As
when loading cut-sheet paper, the Memory Switch setting will determine
the initial position of the paper after auto-feeding, and the micro feed
function may be used to adjust the paper position.

8 Remount the top cover rear cover and the transparent printer cover.

9 Remount the paper guide as shown below:

Once the paper has been loaded

The printer will now be on-line (the ON LINE indicator will be lighted). You

may now want to choose a font, a pitch and a print quality. This can be done
from the front panel, but you must put the printer off-line first by pressing
the @%G button. The indicator will go out and the printer will beep to
confirm this.

Indicators

The first three buttons have a series of indicators next to them which show
which option has been currently selected using them (font, mode or pitch).
Some of these indicators can be either orange or green, depending upon the
options currently selected.

There is no indicator associated with the C~EKI button (as its operation is
obvious when paper has been inserted), but the C=EC and :. 0~ ~3
buttons both have indicators embedded in the buttons themselves. The
indicator embedded in the @I@! 5 button, however does not indicate paper
feed directly, but indicates (when illuminated) whether Quiet mode has been
selected (see below). The C~YYC button also has an embedded indicator.
Pushing the ,: WY-!
and illuminate or extinguish the indicator.

---\ button will alternately set the printer on- and off-line

11

In addition to these indicators, there are two others, POWER and PAPER. The

POWER indicator will illuminate when power is supplied to the printer, and

the PAPER indicator will illuminate when no paper has been inserted.

PITCH SETTING

Usethe CEC button to set the pitch that will be printed. Remember that the

printer must be off-line for you to do this. Successive presses of this button

will illuminate (and select) the following options in this order:

1 Pitch 1 Indicator(s)

10 characters per inch
12 characters per inch

Holding down this button will cycle continuously between these options.

Pitch Panel Lock

If the EC button is pressed when the printer is turned on, the pitch will
be “locked”, and no pitch changes can be made from software. It is still
possible, however, to put the printer off-line and change the pitch using the

T PIGS button.

QUALITY SETTING

The printer is capable of 3 print quality modes: Super Letter Quality (SLQ),
Letter Quality and Draft. Successive presses of the ‘YOOE: button will
alternate between these three settings(the SLQ mode is indicated by the top
indicator showing orange). Remember that the printer must be off-line for
you to do this. Holding down this button will cycle continuously between
these three options. However, not every typeface can be printed in every
mode (see the table below for details of what fonts are available in each
mode), and so the FONT indicator may change as you change the mode.

12

Mode Panel Lock

If the :3EJ button is pressed when the printer is turned on, the mode will
be “locked”, and no mode changes can be made from software. It is still
possible, however, to put the printer off-line and change the mode using the

I’ YODE button.

FONT SETTING

Pressing the C! button will illuminate a font indicator. Remember that
the printer must be off-line for you to do this. Note that the selection of some

fonts (shown in yellow on the front panel) is shown by an orange indicator,
and the selection of others (shown in green on the front panel) is shown by

a green indicator. Note that not every font is available in every mode (see the
table below). Holding down the ~63 button will cycle continuously
between the fonts available for the mode selected.

PAPER HANDLING

The following sections describe the ways in which you can control paper

feeding, etc by means of the front panel controls:

Form feed

A form feed can be achieved from the front panel in the following way:
1 Put the printer off-line, by pressing the #C&%1 button, so that the

indicator is extinguished.
2 Press the >=R EE button, and keep it depressed.
3 Press the ’ 0~ ~5 button momentarily.

4 The paper will then move forward to the top of the next sheet (fanfold

paper), or eject a cut sheet.

5 Set the printer on-line again (‘- 0~ LIE :Z button) to resume printing.

Paper parking

Paper parking is useful if you am using fanfold paper, and you want to print

a document on one or two sheets of cut-sheet paper. The printer “parks” the

fanfold paper safely out of the way, so that you do not need to unload the
paper before inserting cut-sheet paper, then, when you have finished
printing on cut-sheet paper, moves the fanfold paper back to its original
position so that you can restart printing.

To use this facility, follow the instructions below:

1 Put the printer off-line (press the C~ @+1 button, so that the indicator goes

out).

14

2 Press the CG&SC button, so that the fanfold paper is moved out of the

paper path.

3 Now move the release lever to the rear of the printer ( c position) to select

cut-sheet paper (disengaging the fanfold sprockets).

NOTE

If you do not move the release lever at this stage, the printer will warn you
at the next step by emitting a continuous series of beeps.

4 Insert the cut sheet paper in the paper guides
5 Press the C~S!SF button in order to feed the cut sheet to the starting print

position. The printer will automatically go on-line.

6 Print as normal on the cut sheet(s), and when you have finished printing,

put the printer off-line (by pressing the [ w u&I: button again).

7 If the sofiwarc has not done this for you, eject the paper by pressing the

‘:w?$%:‘ button.

8 Move the release lever to the front of the paper (m position) to select

fanfold paper (engaging the fanfold sprockets).

9 Now feed the fanfold paper to the print position by pressing the ~C%ZZF

button. The paper will move to its former print position, and the printer

will automatically go on-line.

You are now ready to start printing on fanfold paper again.

Short tear-off function

The short-tear-off function is handy when using fanfold paper. It ejects the
paper so that the perforation is just above the transparent cover, allowing you

tear it off without having to open up the printer. It then reverses the paper
feed after you have tom off the paper, thereby starting printing at the top of

the next form. This feature is especially useful if you are using pre-printed

stationery (such as invoices, etc), which will not be printed all together.

To use the short tear-off function, press the %A&! button when the printer

is on-line, and hold it down for a few seconds. When you release the button,
the printer will go off-line, and the paper will move up a few inches, allowing
you to tear off the form.

15

To return the paper to its previous position, press the ~GE3 button once

again. When you release the button, the printer will return to its on-line
status, and the paper will be fed backwards, with the print head aligned with

the top of the next form.

Micro Feed

The Micro Feed facility is useful if you wish to align the paper exactly. It

feeds the paper forwards or backwards in 1/12Oth inch increments.
To use this feature, put the printer off-line (using the GYL@~ button).
Then press the (,LINE button, and either the G!!EE% button (to feed the

paper forwards), or the (353EZ button (to feed the paper backwards).
Holding down these buttons continuously will continue to feed the paper for-

wards or backwards in small increments.

BUFFER CLEAR/RESET

It is possible to clear the buffer of the printer or to return it to its power-on

status by using the front panel buttons without having to turn the power off

and on. To do this, put the printer off-line (press thee YY~ button), and then
press the “, ~+3 button again. Before releasing the Z~NE~ button, hold

down the G3 button. Releasing the
holding it down (before releasing the NC

the ” -YYE button) will reset the printer back to the settings at power-on.

TESt AND MAINTENANCE SETTINGS

The printer is equipped with a number of functions to assist testing and main­tenance. Since it is anticipated that they will not be used very often, they are
not described here, but in Chapter 6.
However, briefly, they are:

l A text test print mode

l A short test print mode
l A long test print mode
l A hexadecimal dump mode
l A bidirectional print test

SETTING UP

THE MEMORY SWITCHES

In addition to the pitch, print mode and font, many other options regarding
the setup of the printer can be carried out from the front panel. To access
these options, it is necessary to turn off the printer, and then turn it on again,
while holding down the 0~ LINE .

The principle involved is that the printer will print a list of options on one

line. You use the :?Z%C and C+ ~~~ buttons to move the print head so that
it is below the option you want to choose.

The printer will move the paper up and down as appropriate, so that the menu

options are visible.
The ‘XEC button moves the print head one option to the left, and the

T’- + button moves one option to the right (as marked in blue on the front

panel under the buttons). Holding down one of these buttons will still move
the print head only one option forward or back.

When the print head is below the desired option, press the ,7~+3 button to
enter this into the printer’s memory. Any option chosen at this stage will now

. be stored, even when the printer is turned off.

17

When you press the i my9 button to enter an option, a “*” (asterisk) will
be printed to confinn that the option has heen chosen.
The menus are organized in a hierarchical (tree-structured) fashion. Some
menus do not choose options directly, but instead, move down to other
menus. To move up through the menu structure towards the “root” or
“trunk”, use the

‘+ button as an G?3 button (as marked in blue

underneath the button).
The structure of the menus is shown below.:

Main menu

The options within each menu are given below.

As mentioned above, when you press the (.,, button from any sub-menu
or from an option within a menu, you will return to the menu level above the
current one. If you press the (53 button from the main menu, the printer
will print

“***END***” and exit to being on-line, with the settings chosen

in Memory Switch mode being now set in the printer.

MENU OPTIONS

The following is a list of the options within the menus, and their meanings,
together with the prompts printed in Memory Switch mode. The prompts are
given in capital letters in square brackets, thus: [OFF]. Factory settings are

marked here with an asterisk (for example, [ON*]). A summary of factory

settings is also provided following this section.

Command Menu

This menu allows you to set up various parameters controlling the overall
setup of the printer:

RAM USAGE

QUIET MODE

GRAPHICS

DIRECTION

AUTO ON-LINE

The printer RAM may be used as a print buffer

[BUFFER*], for downloading fonts [DOWNLOAD], or

as a single-line buffer [ lLINEBUFFER] .
The printer may either print slower and quieter [ON], or

faster, malting slightly more noise [OFF*].

When printing in graphics mode, the printer may either

print bidirectionally (in alternate directions) for speed
[BI*] or in one dire&on only (unidirectional for in­creased accuracy KINI]. For practically all purposes,
however, bidirectional printing is sufficiently accurate.

If this is set [ON*], then when paper is inserted, the
printerwillautomaticallycomeon-line.Ifset [OFFl,then
you will have to press the button to bring the printer on-

line.

Font Menu

This menu allows you to set two parameters concerning fonts which will be
automatically selected whenever you turn on the printer:

) ZEROSTYLE In computer usage, a zero is often written with a slash

through it, as follows: “0”. This style is called

SLQ/LQ FONT This option allows you to choose the default font selected

when SLQ or LQ mode is selected. All available fonts are
given as options. The default is [COURIER*].

With this option, you may selector cancel the Automatic
Sheet Feeder option [OFFS] or [ONI.

When you load paper automatically, this option deter­mines the number of lines by which the paper will be fed
forward from the top of the paper. The options range from

1 to 6, and the factory setting is 6.

Forms Menu

This menu allows you to set various options associated with paper handling:

SHORT TEAR OFF When using fanfold (continuous) paper, this Short Tear

Off option allows you to tear off one sheet of paper
without having to eject the whole of the following sheet.
If this option is set [ON*], when the paper reaches the top
of the form, it will automatically be advanced a little,
allowing you to tear off the paper easily. Set this option
to [OFFI if you do not want to use it.

PAGE LENGTH

When using fanfold (continuous) paper, you may wish
printing to stop a little before the bottom of each sheet,
and start printing a little after the beginning of the next (in
other words, skipping over the perforation). This is useful
if you want to produce program listings, etc. This can be
enabled by setting this option [ONI, or, if using software
which performs this function automatically, it can be set

10~1.

If set [ON, this will expand all received carriage return
codes to a line feed and carriage return pair. However,

this may be set [OFF*] if your software demands it.
If set [ON*], this function will expand all received line

feed codes to a carriage return and line-feed pair. How-

ever, this may be set [OFF] if you do not want to be

expanded.
This sets the number of lines per vertical inch which will

be printed to [3 LPI], [4 LPI], [6 LPI*] or [8 LPI].
The page length may be set by means of the DIP switches

[DIP-SW*] (see Chapter 5 for details) or to any of the

following lengths (in inches): [33, [3.5], [4], [5.5], [6],

[7], [8], [8.5], [11.7] or [14]. A4 paper is equivalent tc

11.7 inches, while the DIP switch settings of 11 inches

and 12 inches will normally be used for fanfold paper.

EMULATIONS

AND ESCAPE CODES

EMULATIONS

The printer has two emulation modes: standard mode and IBM mode.
In standard mode, the printer emulates the functions of the Epson LQ-850
and LQ- 1050 printers, as well as the NEC Pinwriter. Additional command
codes are included as a superset of these emulations.

In IBM mode, the printer emulates the IBM Proprinter X24/XL24 printers.
Additional command codes are included as a superset of these emulations.

The emulation is changed by means of DIP switch 1. When ON, the printer
will be in standard mode, and when OFF, the printer will be in IBM emula­tionmode (see Chpter 5). It is not possible to change the emulation mode by
means of software control or the front panel controls.

NOTE

1 Remember to turn off the printer before making any DIP switch changes.

NUMERICAL REPRESENTATION

When in either standard or IBM mode, any numerical parameters taken by

command sequences are usually binary rather than ASCII numerical values.

In this manual, any ASCII values will be represented in quotes, eg “21” will
represent the ASCII string 32h concatenated with 31h (in BASIC,

CHR$(SO)+CHR$(S 1)). Usually in these examples, however, hexadecimal
values will be quoted, as shown by the lowercase “h” following the number,
eg 32h.

Binary numbers. over FFh are obtained by dividing the number into two

bytes, the first being the low byte, and the second being the high byte. In this

way, the value 123h will be divided into the two following bytes: 23h and

Olh.

If negative numbers am required, they are obtained by subtracting the

absolute value of the negative number from 65536 (lOOOOh), and dividing

. the result into high and low bytes. For instance, to represent the number - 1 Oh,

the following operation is carried out:

23

1OOOOh - 1Oh = FFFOh
and the result is divided into the two bytes of FOh and FFh.

If “non-printable” codes are given, ie those codes from OOh through 1Fh and
7Fh, these codes will be enclosed in angle brackets, for example <DCl>.
The name in the angle brackets is that assigned to the code in the ASCII con­vention. The name of the character should not be used, the binary value
should be input. In the same way, it should be noted that the angle brackets
are not to be input - they are merely there as delimiters in the printed text.

Of course, in a program, a meaningful variable name can be given to these
characters, for instance (the following example is written in BASIC):

10 ESC$=CHR$(27) :BS$=CHR$(8)
20 LPRINT ESC$;BS$;

COMMAND CODES AND ESCAPE SEQUENCES

Some command codes are common to both the standard and IBM modes. In
the descriptions of the command codes, all command codes will be given,
together with a note of the modes to which each command code is applicable.

Most of the following command codes ate available in both the standard
mode and the IBM emulation mode. If a command is common to both
modes, the descriptive heading is followed by “Both”. If the command is
specific to one mode, then either “Standard” or “IBM” will follow the

descriptive heading. Occasionally, there are two identical commands to
perform the same function. In these cases, the relevant sign follows the
escape sequence.

When parameters are given, the accompanying text describes whether the
parameter is an ASCII character or a binary value.

In the following descriptions, first the function of the command sequence is
given. This is followed by the emulation for which this command is
appropriate (“Standard”, “Both” or “IBM”).

24

Following the heading, the full form of the command is given, using the
ASCII names for control codes, eg <ESC> (the angle brackets on either side
of the name are not part of the name, being simply delimiters, and should not
be entered). Variable parameters are indicated by a letter (usually “n”), and
an optional number, enclosed in angle brackets (eg <nO>). Where an
indefinite number of parameters are to be supplied, the <n>s are separated
by an ellipsis ((I.. . “). The sequence is then given using hexadecimal codes
(two hexadecimal digits followed by a lowercase “h”), with variables again
represented by letters enclosed in angle brackets. The decimal equivalent

follows the hexadecimal. The following is an example:

The command above enables the definition of “soft” characters to be downloaded.
The following rules are observed. <cl> and <c2> are binary values which determine
the character range which will be replaced by downloaded data. For instance, if
<cl>=20h and cc2>=30h, all characters from 20h through 30h will be overwritten
by the downloaded data. If a downloaded character is stored in the area 80h through
9Fh, it can only be primed in the character set #2 mode. It is possible to store
downloaded characters in the part of the character set reserved for IBM block
graphics @Oh through DFh, F4h and F5h), but these characters can only be printed
when the standard character set has been selected.
<ao>, cab and cu2> are attribute bytes, setting the starting dot column, printable

The vertical definition of the characters is 16 dots in superscript/subscript modes,
and 24 in all others. Each byte therefore represents half of the vertical definition of
a character column in superscript/subscript mode, and a third of the vertical
definition in other modes. If cn> bytes are required for a normal character, the
arrangement of these bytes is as follows (where the byte numbers are represented by
decimal numbers, starting at 0), and the total width of the character has been defined
by the parameter <al>:

In the case of a superscript/subscript character, the width has also been defmed by

follows:

table below), and<& and al> are binary values (low byte first) giving the number

of graphic data bytes following (as represented by <do> . . . cdn>). The actual
number of data bytes varies according to the graphic mode chosen. In an 8-pin mode,
the number of data bytes is equal to the number of graphic columns to be printed, but
in a 24-pin mrxle, the number of data bytes is three times the number of graphic
columns to be printed.

sophisticated electronic device, which also contains high voltages inside.
For that mason, only carry out those operations described in this section.

CAUTION

Any attempt to carry out operations other than those described here may result in
electric shock and/or damage to the printer. When carrying out any repairs or
maintenance, always follow the instructions carefully.

TROUBLESHOOTING

Your printer is a reliable piece of precision machinery, which should not
cause you any trouble, provided it is used and treated sensibly. However, the
few elementary tips below should avoid you having to make unnecessary
service calls. The following table gives you ideas on where to look in this
section if you experience faults:

Remember - it is better not to attempt operations or repairs above your level
of competence. Otherwise, you run the risk of damaging the printer.

75

Power supply

If the POWER indicator does not illuminate, check the following:

1 Check

Is the power cable properly
plugged into the electrical
outlet?

Is power being supplied to
the outlet?

Is the printer voltage correct?

1 Possible remedy

Turn off the printer, ensure the power cable is securely
connected. and then turn the printer back on.

Turn off the printer, unplug it, and try with another
appliance to determine if electricity is being supplied to
that outlet.

Ch~kthebonompanelofyourprintertoensurethatthe
outletvoltage corresponds to thevoltagerequiredby the
printer. If they do not match, DO NOT try to operate the
printer. contact your supplier.

Printing

If your printer does not print, or suddenly stops printing, check the follow-

ing:

Check
Is the interface cable con-

nected securely?

Is the ON LINE indicator illu­minated?

Is the PAPER indicator illu-

minated?
Is the paper caught up inter-

nally? (

Is the ribbon caught up
around the print head?

Is the software you are using
properly installed for your
printer?

Can the printer perform self­test operations?

Possible remedy
Check both ends of the cable - printer and computer to

make sure that the connector is fvmly in position.
If it is not, press the ‘$c$ button to set the printer on-

line.
If it is. the paper has run out. Load more paper.

Turn off the power, remove the jammed paper, replace,
tumontheprinter, andcontimteprinting.Makesurethat
the leading edge of the paper is smooth and uncreased.

Turn off the power, remove the ribbon, retension it, and
replace it. This problem occurs most frequently with a
worn ribbon, so you may need to replace the ribbon.

Check the installation settings in your software, and re­install if necessary.

Tum the printer off, and turn it on again, holding down
one of the buttons to perform a self-test. If these do not
work, contact your dealer.

76

If the print is faint, or uneven, check the following:

Check
Is the ribbon properly in-

stalled?
Is the ribbon worn out?

Possible remedy

Check and reinstall if necessary.

The ribbon has a long life, but eventually will need
replacing. Fit a new ribbon cartridge if necessary.

If dots are missing in the printing, check the following:

Check

Are dots missing at random

in the printing?

Is a line of dots missing con-

sistently throughout the

printing?

Possible remedy
The ribbon has become slack, causing it to get caught

up. Stop printing, remove the ribbon cartridge, reten­sion and replace it.

The print head is damaged. Stop printing, and contact
your supplier for a new print head

If your application software cannot print the fonts or characters selected,

check the following:

Check
Is your application software

properly installed?

Are fonts not being selected
Properly?
Are characters other than

those

printed?

expected being

Possible remedy
Check the software installation, andre-install the soft-

ware if necessary.

Check the software installation, and insert the com­mands necessary for font changes into the software.

Either you are using the wrong International Character
Set (reset with DIP switches or software commands).
or you have the wrong character set selected (for
example if characters other than IBM block graphic
characters are being printed). Correct this with DIP
switches or the appropriate software sequences.

If the printout is not what is expected:

1 Check

Is the printer installed cor­rectly?

Is the printer not printing
anything that you are expect­ing?

I Possible remedv

Your software may think that it is driving a different

emulation to the one actually set Check the DIP switch

settines to make sure YOU have the rieht emulation.

Use the Hex Dump mode to analyze the output from the
computer to the printer. This will enable you to deter­mine that the right escape sequences, etc are being

transmitted.

77

Paper feeding

If cut sheet paper (without the ASF) is not feeding smoothly, check the
following:

1 Check

Is the paper release lever
pushed back (to the f posi­tion)?

Is the paper guide in place

and vertical?
Are the left and right guides

too close together?

Is the ASF selected with the
Memory Switch settings?

Are you trying to feed paper
using the front panel buttons
while the ON LINE indicator
is illuminated?

Is the paper too thick?

1 Possible remedy

Set the release lever to the h position.

The paper guide should be in place vertically for cut

sheets to feed smoothly.

If the left and right guides are too close together, the
paper will not feed smoothly. Move them a little further

apart to allow the paper to feed freely.
If it is, then deselect it.

You can only feed paper in this way when the printer is
off-line. Set the printer off-line and then feed paper.

There are limits to the thickness of paper that can be fed
in this way. TW with thinner oaner.

If fanfold (continuous) paper is not being fed correctly using the tractor feed,
check the following:

Check
Is the paper lever pushed to

the C position?
Is the paper guide in the ver-

tical position?
Are the holes on each side of

the paper aligned withregard
to each other in the sprock­ets?

Are the sprockets too close or

too far apart?

Are the sprockets locked in
position and the covers
closed?

Is the paper feedii freely
into the printer?

Possible remedy
Make sure the release lever is pushed to the h position.

When using the tractor feed, the paper guide should be
horizontal.

If the two sides of the paper are out of alignment realign
them so that the sprocket holes match up.

Misalignment of the sprockets, making the paper too
loose or too tight, will prevent a smooth paner feed.

Correct this if necessary.

The paper should not be too far horn the printer (less
than 1 meter/ 3 feet), and there should be no cables or
other obstacles obstructing its path. The paper should
also be feeding straight into the printer, and an angled
feed may cause iams and blockages.

76

Check
Are you trying to feed paper

using the front panel buttons
while the ON LINE indicator
is illuminated?

Is the paper too thick?

Possible remedy

You can only feed paper in this way when the printer is

off-line. Set the printer off-line and then feed paper.

There are limits to the thickness of paper that can be fed

in this way (one top copy and three NCR copies). Try

with thinner paper.

If the ASF is not operating or is not feeding paper correctly, check the
following:

Check

&as the ASF option been

selected using the Memory
Switch functions?

Is the release lever set to the

l position?

Is the ASF correctly

mounted?
Is paper caught up near the

print head?

Are the left and right guides
too close together?

Is there too much paper in the
paper feed hopper or stacker?

Was the paper fanned before
being fed into the ASF?

Has the paper been used al-

ready or is it creased?

Are you trying to feed paper

using the front panel buttons

while the ON LINE indicator
is illuminated?

Isthepapertoothickortoo
hill?

Possible remedy

Select this option

The release lever should be set to the single-sheet
position.

Make sure that the ASF is properly seated on the printer.

Stop printing, remove the jammed sheet (you may have
to remove the ASF for this), and contimre.

If the left and right guides are too close together, the
paper will not feed smoothly. Move them a little further

apart to allow the paper to feed freely.
The ASF’s paper feed hopper and stacker can hold 120

sheets each. Make sure that there is no more paper than

this in either the hopper or stacker.
If,this is not done, paper jams may occur. Remove the

stack of paper from the ASF and fan it before reinsert-

ing.
Only new, uncreased paper should be used with the

ASF.
You can only feed paper in this way when the printer is

off-line. Set the printer off-line and then feed paper.

There are limits to the thickness of paper that can be fed
in this way. Try with different paper.

79

If the paper park facility does not appear to be working correctly, check the
following:

1 Check

Is the paper release lever in

the m position?
Has the fanfold paper been

properly parked?

I Possible remedy

The paper release lever must be set to the & position
after the fanfold paper has been parked.

Make sure that the PAPER indicator comes on after the
fanfold naner has been uarked.

If the short tear-off function does not appear to be working properly, check:

Check

Has printing ended in the

middle of a page?

Possible remedy
Either send a <FF> or enough <LF> commands to eject

the page.

If text is being printed all on one line, or with extra blank lines, check the
following:

1 Check

Is the text all on the same
line?

Is text being printed with
extra blank lines?

1 Possible remedy

Carriage returns are not being expanded to
<CR> +<LF> pairs. Check the Memory Switch setting
and correct.

Two line feeds are being printed. Either make your
software print just a carriage return or (if this is not
possible), set the AUTO LF to OFF using the Memory
Switch menus.

If the page length and margins are not what is expected, check the following:

I

I

Check
Is the piriming starting too

high or too low on the page?
Does the printer’s page

lengthnotmatchthephysical
page length?

Is the Skipover perforation
facility not working?

60

Possible remedy
Use the Micro Feed facility to adjust the print position

relative to the page.
Use the Memory Switch settings, or the DIP switch to

set up the correct page length, or use software com­mands to do it.

Make sure this is set with the Memory Switch menus. If

the skip occurs in the wrong place, make sure the page
length is properly set, and that the top of the print

position is about two lines down from the top of the
Paper-

EVERYDAY MAINTENANCE

Essentially, your printer is a robust piece of equipment, but should be treated

with a modicum of care in order to avoid malfunctions. For example:

Keep your printer in a “comfortable’* environment. Roughly speaking, if

you are comfortable, then the environment is suitable for your printer, too

(see Chapter 1).
Do not subject the printer to physical shocks or excessive vibration.
Avoid over-dusty environments. Dust is the enemy of all precision me-

chanical devices. If you have to use the printer in such an situation, you

might like to consider the use of an acoustic hood, whose primary

function is to reduce the printer’s noise, but can also act as a barrier against

dust. Consult your supplier for details of a suitable model.

To clean the exterior of the printer, use a barely damp cloth (use either

water with a little detergent or a little alcohol), but do not allow any liquid

to fall inside the printer.
The interior of the printer may be cleaned with a small vacuum cleaner or

a compressed-air aerosol (sold for this purpose). When performing this

operation, be sum not to bend or damage any cable connections or

electronic components.

ADJUSTING THE PRINTING GAP

The distance between the print head and the platen can be adjusted to

accommodate different paper thicknesses. To make this adjustment, remove
the top cover. The adjustment lever is located near the left end of the paper
bail. pulling the adjustment lever towards you widens the gap; pushing it
away from you narrows the gap.

There are four positions; you can feel the lever clicking into each position.
The first position (narrowest gap) is the one most commonly used for single

sheets of paper. Try different positions until you get the best printing results.

81

RIBBON REPLACEMENT

The ribbons used by your printer are endless-loop ribbons in which the
ribbon is recycled. When the print quality becomes too faint, you will need
to replace the ribbon. Use only ribbons recommended for use with the printer

(your supplier will be able to advise you).

1

To remove the old ribbon from the printer, first turn off the power.

2

Remove the top cover, and hold the ribbon by the two lugs on each side.
Push in the two lugs slightly, and pull upwards to remove the ribbon.

Ribbon tensioning knob

82

3 Take the new ribbon and tension it by turning the knob on the top of the

ribbon cartridge clockwise.

4 Now insert the ribbon cartridge into the holder gripping it by the lugs, and

turning the knob slightly clockwise if necessary. Make sure that the

ribbon goes between the print head and the platen guard (see illustration
below).

Print head shield

5 Now replace the top cover and turn on the printer. You are now ready to

start reusing the printer.

REPLACING THE PRINT HEAD

This is not a job which you will need to do very often. The print head has been
designed to give a life of about 200 million dots. In normal everyday use, this

will mean years of life. However, if the print quality is faint, even after you

have changed the ribbon, the print head will need replacement.

Only use a replacement print head as recommended by your supplier.

NOTE

This is a fairly tricky operation. Read the instructions below carefully before
attempting it. If you are in any doubt as to your competence to perform it, call in
the experts before you start.

1 Turn OFF the printer, and remove the power cable.

2 If the printer has been in operation immediately before this operation, the

print head will be hot.

NOTE

Allow time for the print head to cool before attempting to work on it,

3 Open the top cover.

4 Remove the ribbon cartridge (as described above)

5 Using a Phillips-type screwdriver, carefully unscrew the two bolts

securing the print head to the print head assembly (see the illustration
below).

I

6 Full the print head firmly upwards, releasing the print head card edge con-

nectors from the connector mounted on the chassis.

7 Remove the retaining screws and washers from the print head assembly.

Put them on one side.

8 Take the new print head, and locate it in position, making sure that the

card edge connections fit securely into the chassis connector.

84

rTPrint head bolts

NOTE

DO NOT apply excessive force, as this may result in damage to the print head.

9 Fasten down the new print head using the retaining washers and screws.

Do not apply excessive force when tightening the screws, as this may strip

be thread, but ensure that the print head is firmly secured.
10 Replace the ribbon cartridge.
11 Replace the top cover.
12 Re-insert the power cable and re-apply power. Your printer may now be

used. You may like to check the print quality using one of the test print
procedures (see below).

85

FRONT PANEL DIAGNOSTIC AND TEST MODES

The printer is equipped with a number of different modes for diagnosis and
testing. These are accessed from the front panel by holding down a front
panel button (or combination of buttons) while turning on the power to the
printer.

The test and diagnostic modes available am listed below

9 A text test print mode
9 A short test print mode
. A long test print mode

l A hexadecimal dump mode
l A bidirectional print test

Short test mode

If the printer is turned on while the T
enter the short self-test mode. The printer will start printing as soon as the

!ZZFFFZ button is released, and will print the version number of the printer’s

ROM, eg “*** Ver 1.0 ***“, followed by seven lines of the character set.
Each line will he offset by one character from the one before it. If the color

option has been installed, each line will be in a different color. The final
(black and white) result will be something like the following:

0~ u=J button is pressed, the printer will

[Standard mode]

[IBM mode]

Since the test print occupies the whole width of the carriage, it is recom­mended that the printer is loaded with continuous stationery to avoid
possible damage to the print head and/or platen.

86

Long test mode

If the printer is turned on while the C-E%
enter the long self-test mode. The printer will start printing as soon as the

M-R FEE,

ROM, eg

each typeface and pitch available.
Since the test print occupies the whole width of the carriage, it is nxom­mended that the printer is loaded with continuous stationery to avoid
possible damage to the print head and/orplaten. In addition, the total number
of lines printed is considerable, more than can be accommodated on a single
sheet, so fanfold paper is certainly suggested for this test.
The printout below shows a short sample of the results of this test:

87

Text test mode

In this mode, the printer will print the Memory Switch menus and options.
This mode is accessed by turning on the printer at the same time as holding
down the CIfEBEZ button.
The resulting printout will be similar to the example below:

Hexadecimal dump mode

In this mode, all received data will be printed in a hexadecimal dump format,

rather than the control codes being acted on as command codes.

This mode is accessed by tuming on the printer, while simultaneously

holding down the
necessary to turn off the printer completely.

The printout will be similar to that produced by a MS-DOS DEBUG Display
command, ie the hexadecimal values of the bytes received will be given in

tows of 16, divided into two blocks of eight. “Unprintable” characters, ie
control codes from OOh through 1Fh and 7Fh through FFh, are represented
by periods.

The following (BASIC) program will produce the result below it:

10 FOR I=0 TO 255
20 LPRINT CHR$(I);
30 NEXT I
40 LPRINT
50 END

After the program has been run, the printer’s buffer should be flushed by
pressing the i button.

Bidirectional test/adjustment mode

This mode is used to adjust the alignment of the print head on successive
bidirectional passes. After a period of some months, your printer may work
itself out of alignment on left and right printing passes, showing itself most
obviously in graphics printing. This mode will therefore be used very rarely.

1 Turn the printer off and then turn it on again while holding down the

‘~=/t%

following:

2 The printer will feed the paper forwards and backwards during this

operation, allowing you to view the paper for optimum alignment.

3 The vertical lines are in fact composed of three lines, the top and bottom

being printed on one pass of the print head, and the middle on a pass in
the opposite direction.

4 To adjust the printing, use the rSB and ?!EYFE~ buttons.

and C~m~u=X buttons. The printer will then print something like the
