FORM

(TOF)

1

CAUTION!

If you turn the platen knob when the printer is not at Top of Form,
the TOF will misalign. Always feed the paper to TOF before turning
the platen knob!

Using your printer > 30

NOTE

> Your software may print the first line of print above or below where TOF is

set. You may need to adjust the TOF to meet your software’s
requirements.

> The Top of Form and Forms Tear-Off settings of your printer interact. How

you set the Top of Form depends on whether Forms Tear-Off is ON (set to
500 ms, 1 sec, or 2 sec) or OFF (the factory default setting).

F

ORMS TEAR-OFF

The Forms Tear-Off feature allows a printed continuous forms page to be torn off without
wasting paper or adjusting the printer.

When printing stops, Forms Tear-Off automatically moves the paper to align the perforation
with the tear bar (located under the access cover), after a time interval which you select
through the menu.

Paper remains in the tear-off position until the printer receives more data. Then, the paper
moves back down for printing.

This feature has to be enabled.
There are two ways to determine the status of the Forms Tear-Off menu setting:

> Print the Menu.
> Use the TEAR key.

To print the Menu:

ORMS TEAR-OFF FEATURE

This feature is normally turned off. To use Forms Tear-Off, you must enter the menu and
change the setting to the desired time interval (see “Changing the forms tear-off setting”

on page 34).

The Forms Tear-Off feature allows a printed continuous forms page to be torn off without
wasting paper or adjusting the printer. It can be used for rear feed continuous forms,
bottom feed continuous forms (with the optional push tractor installed), or for top feed roll
paper (with optional roll paper stand installed).

When the printer is turned on, the paper feeds to the tear-off position.
When data is received, the paper automatically moves down to the print position (TOF) and

printing begins.

NOTE
You can also move the paper down to the print position manually by pressing
TEAR.

Using your printer > 33

When printing stops, Forms Tear-Off automatically moves the paper to align the perforation
with the tear bar (located under the access cover), after the time interval which you
selected through the menu.

Paper remains in the tear-off position until the printer receives more data. Then, the paper
moves back down for printing.

NOTE

> The status of the Forms Tear-Off menu setting affects how you set the

Top of Form: see “Top of Form (TOF) and Forms Tear-Off” earlier in this
chapter.

> Do not use Forms Tear-Off with labels or multipart forms!

> Forms Tear-Off cannot be used when the optional pull tractor is engaged.

P

OTENTIAL ISSUES WITH SOFTWARE PACKAGES

If Forms Tear-Off is set to ON and the software package you are using “pauses” for a long
enough interval while sending data to the printer, Forms Tear-Off may be activated. No
data is lost, but this causes uneven print registration due to the paper movement.

If this occurs, use the menu to turn off this feature, then use the TEAR key to move the
paper up to the tear position manually (see "Changing the forms tear-off setting").

HARACTER PITCH

1

Character pitch determines how many characters will print on each line. You can choose a
specific fixed width (10 to 20) for each character in characters per inch (CPI). The higher
cpi settings are often used for spreadsheets.

Proportional (PROP) sets character widths based on the character itself: e.g., the letter i is
assigned a narrower width than the letter m. This provides a more polished, typeset
appearance.

To select Proportional, press the CHARACTER PITCH key until both the cpi value and PROP lights are illuminated.

To select non-proportional, press the CHARACTER PITCH key until the light for the cpi value
you wish to use is illuminated.

ENERAL PROBLEMS

Here are some general things to check before proceeding with detailed troubleshooting.

> Is the printer plugged in and turned ON?
> Are the connections (power and interface) secure?
> Is the product being operated under the proper ambient conditions?
> Does the paper being used meet the specifications for this product?
> Is the paper properly installed?
> Is the ribbon properly installed?
> Is an Oki ribbon being used?
> Is the printhead gap correctly set?
> Are the correct printer drivers being used for the printer?

NOTE

> Settings in your software application will normally override any settings in

your printer driver.

> Printer driver settings normally override settings from the printer menu or

printer front panel.

PROBLEM SOLUTION

My word processor files
do not print the way I
have the menu and front
panel set.

Nothing happens when I
turn ON the printer.

The printer does not
print when the computer
sends data.

Remember:

> Settings in your software application can override settings

in your printer driver.

> Your printer driver settings can override any settings from

the printer menu or printer front panel.

Before sending a file to the printer, many word processors send
either an “initialisation string” or an I-Prime signal to the printer.

The initialisation string contains codes that override the panel
and menu settings. To change your printer to ignore the reset
code, enter the Menu Mode, go to the Set-Up group and change
the setting for Reset Inhibit to YES.

The I-Prime signal will automatically override any front panel
settings you have made. To eliminate this problem, enter the
Menu Mode, go to the Parallel Interface group and change the
setting for I-Prime to Invalid.

For more information on changing menu settings, see “Changing

the menu settings” on page 42.

Check the power cord connection to the outlet and to the printer.
If you are using a power strip, make sure it is turned ON, and
that the fuse hasn’t blown or that the circuit breaker hasn’t
tripped.

1. Is the SEL light on? If not, press the SEL key.

2. Check that the interface cable is securely connected to both
the printer and the computer.

3. If you have the optional serial interface board installed, check
to be sure that it is firmly seated in the printer.

I'm getting strange
symbols, incorrect fonts,
etc., when I try to print

a document.

1. Check to be sure that the printer driver you have selected in
your software matches the printer emulation.

2. Press SHIFT and SEL keys, then press GROUP key.
This will print a line showing the emulation you have

selected.

3. If you have embedded any printer commands in your

software, check to be sure that you entered them correctly

Troubleshooting > 62

PROBLEM SOLUTION

Ink smears on the paper
when I print narrow
columns.

I've installed a new
ribbon and the printing
is smeared and
streaked.

There are dots missing
in my printouts.

The ALARM light is
flashing.

The ALARM light is ON
and the Character Pitch
10 light is flashing.

This may be caused by excessive printhead travel from the
centering position. Enter the Menu and set the Centering Position
to MODE 1. See “Using Your Printer, Menu Mode.”

For the wide-carriage printer, if MODE 1 doesn't work, try setting
the Centering Position to MODE 2.

The ribbon shield (1) is either loose or missing.

1

Remove the ribbon cartridge and check the ribbon shield.

> If it is loose, secure it.
> If it is missing, find it and install it.

The head gap may not be set correctly. Try moving the headgap
lever.

Try turning the printer OFF and then back ON again. If the light
still blinks, call for service.

This indicates that the paper lever is set at the wrong position for
the paper you are trying to use. Move it to the proper setting.

The ALARM light is ON
and the Character Pitch
15 light is flashing.

The printer needs paper.
The ALARM is not ON
and I can’t load paper.

Continuous form paper
sticks to the sheet
guide.

The Print Quality and
Character Pitch keys on
the front panel don't
work.

This indicates a paper jam. Press the SEL key and correct the
paper jam situation. See “Clearing paper jams” on page 58.

1. Press and release the SEL key.

2. Press and hold the SHIFT key and press the RESET/

CHARACTER PITCH key.
The ALARM light illuminates and you can now load paper.

In cold dry weather, static charges can build up and make the
paper cling to the sheet guide. Try moving the paper guides
together so that the paper rests on the guides rather than on the
separator.

The Operator Panel Function in the printer menu can be used to
disable these buttons (Limited Function). If the printer is part of
a customized system or if it is used by a number of people, the
system manager may have used this option to make sure the
printer is always set properly.

Check with your system manager before changing any menu
settings.
