Saving Money  
Saving Money: Draft Mode  
Saving Money: Forms Tear-Off  
When printing drafts of documents, use either the High Speed  
Draft or Super Speed Draft mode. These modes use less ink  
than the Utility or Near Letter Quality Modes, thus extending  
the life of your ribbon. The draft modes also print at high  
speeds, reducing the time required to complete a print job.  
The Forms Tear-Off feature allows a printed page (rear feed,  
continuous form) to be torn off without wasting paper or  
adjusting the printer.  
Forms Tear-Off automatically moves the paper from the  
initial printing position (print start position) to the tear-off  
position, after a time interval (which you select through the  
menu).  
For more information, refer to “Using Your Printer, Print  
Quality.”  
The top of the page (perforation) is even with the tear bar.  
The tear bar is located under the clear top of the access cover.  
Paper remains in the tear-off position until the printer  
receives more data. Then, the paper moves back down for  
printing (retracts to the initial print position).  
When printing stops, the paper will advance to the tear-off  
position.  
This feature is normally turned off.  
Forms Tear-Off and the Top of Form settings interact.  
For more information, refer to “Using Your Printer, Forms  
Tear-Off and Using Your Printer, Top of Form.”

Operation Tips  
Operation Tip: Top of Form  
If you turn the platen knob when the printer is turned  
!
!
on, you will cause the Top of Form to mis-align. Always  
turn the printer off before turning the platen knob!  
The first line prints at the red line of the plastic paper shield  
(1) on the printhead.  
Always determine the status of the Forms Tear-Off menu  
setting BEFORE setting the Top of Form. Refer to  
“Using Your Printer, Top of Form, Forms Tear-Off  
Status (ON or OFF).”  
The Top of Form and Forms Tear-Off settings of your printer  
interact.  
How you set the Top of Form depends on the status of the  
Forms Tear-Off menu setting.  
For more information, refer to “Using Your Printer, Top of  
Form (TOF).”  
Top of Form sets the print start position for the printer. It is  
adjustable in increments of 1/144 of an inch. The amount of  
adjustment is limited to avoid paper jams.

Operation Tip: Turning the Platen Knob  
Operation Tip: Control Access to the  
Printer  
If you turn the platen knob when the printer is turned  
!
on, you will cause the Top of Form to mis-align. Always  
turn the printer off before turning the platen knob!  
You can control access to the printer by changing the setting  
for the Operator Panel Function (in the Menu).  
When the Operator Panel Function is set to Full Operation  
(the factory default), all keys on the front panel operate.  
When the Operator Panel Function is set to Limited  
Operation, the PRINT QUALITYand CHARACTER PITCH  
keys don’t work. This prevents these settings from being  
changed from the control panel when several people are  
using the printer.  
For more information, refer to “Using Your Printer, Menu  
Mode, Menu Settings Table, Setup, Operator Panel  
Function.”

Installation  
Installation Hints  
Your printer has a grounded, 3-prong plug as a safety  
feature, and it will only fit into a grounded outlet. If you  
can not plug it in, chances are that you have an older, non-  
grounded outlet. Contact an electrician to have it  
replaced with a grounded outlet. Do not use an adapter to  
defeat the grounding.  
• To avoid damaging the power cord, do not put anything  
on it or place it where it will be walked on. If the cord  
becomes damaged or frayed, replace it immediately.  
• Read the setup and operating instructions in this  
document carefully. Be sure to save this document for  
future reference.  
• Read and follow all warning and instruction labels on the  
printer itself.  
• Place your printer on a firm, solid surface. If you put in on  
something unsteady, it might fall and be damaged. If you  
place it on a soft surface (such as a rug, sofa, or bed) the  
vents may be blocked, causing it to overheat.  
• The printer must be installed near a power outlet which  
will remain easily accessible.  
• Be certain that your power source matches the rating listed  
on the back of the printer. If you are not sure, check with  
your dealer or with your local power company.

Installation Overview  
• If you’re using an extension cord or power strip with the  
printer, make sure that the total of the amperes required by  
all the equipment on the extension is less than the  
extension’s rating. Generally, the total ratings of all  
equipment plugged into any one power line should not  
exceed 15 amperes. Don’t exceed this unless you know  
that the power line your equipment is plugged into has a  
rating above 15 amperes.  
To install your new printer, follow the instructions from the  
“Installation, Installation Location” to “Installation, Printer  
Drivers” sections of this document. You must complete these  
steps for your printer to operate properly.  
If you have purchased an option package for your printer,  
refer to the documentation you received with that option for  
installation instructions.  
• To protect your printer from overheating, make sure no  
openings on the printer are blocked. Do not put the printer  
on or near a heat source, such as a radiator or heat register.  
If you put the printer in any kind of enclosure, make sure  
it is well ventilated.  
Installation Location  
• Place your printer on a firm, solid surface.  
• Allow enough space on each side of the machine to easily  
access the platen knob and the various paper feed paths.  
• Make sure a power outlet is available nearby.

Customizing the Installation  
Your printer has many settings (defaults) that do not need to  
be adjusted as part of a standard installation.  
However, you may need to adjust settings to fit your  
standards.  
Some settings you may need to adjust as part of your  
installation are:  
• Top of Form (TOF)  
• Paper Path  
• Printhead Gap  
To adjust these settings, refer to the appropriate section in  
“Using Your Printer.”

Top of Form (TOF)  
If you turn the platen knob when the printer is turned  
The Top of Form and Forms Tear-Off settings of your printer

on, you will cause the Top of Form to mis-align. Always  
turn the printer off before turning the platen knob!  
The factory default setting for the Top of Form (where  
the printing should begin) is one inch down from the top  
of the page.  
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 needs. Use the procedures  
in “Using Your Printer, Top of Form, Forms Tear-Off  
Status (ON or OFF).”  
How you set the Top of Form depends on the status of the  
Forms Tear-Off menu setting.  
If Forms Tear-Off is activated (set to ON), set the Top of Form  
using “Using Your Printer, Setting Top of Form, Forms Tear-  
Off ON (StepA).”  
If Forms Tear-Off is NOT activated (set to OFF), set the Top of  
Form using the “Using Your Printer, Setting Top of Form,  
Forms Tear-Off OFF (Step B).”

Forms Tear-Off  
When printing stops, the paper advances to the tear-off  
position.  
The status of the Forms Tear-Off menu setting affects  
how you set the Top of Form.  
!
The default setting for Forms Tear-Off is OFF.  
There are two types of Forms Tear-Off.  
To determine the status of the Forms Tear-Off menu  
setting, refer to “Using Your Printer, Top of Form,  
Forms Tear-Off Status (ON or OFF).”  
Automatic Forms Tear-Off  
Manual Forms Tear-Off  
For information on setting the Top of Form, refer to  
“Using Your Printer, Top of Form, Setting Top of Form,  
Forms Tear-Off (ON or OFF).”  
If the software package you are using “pauses” while  
sending data to the printer, Forms Tear-Off may be  
activated (if it is enabled through the Menu). The pause  
must be for two or more seconds. No data is lost. Uneven  
print registration will occur due to the paper movement.  
If the problem occurs, use the menu to turn off this  
feature.  
!
The Forms Tear-Off feature allows a printed page (continuous  
forms, rear or bottom feed, with no pull tractor option  
installed) to be torn off without wasting paper or adjusting  
the printer.  
Forms Tear Off automatically moves the paper from the initial  
printing position to the tear-off position, after a time interval  
(which you select through the menu).  
DO NOT use Forms Tear-Off with labels or multi-part  
forms!  
!
!
Forms Tear-Off CANNOT be used when the optional  
pull tractor is engaged.  
The top of the page (perforation) is even with the tear bar.  
The tear bar is located under the clear top of the access cover.  
Paper remains in the tear-off position until the printer  
receives more data. Then, the paper moves back down for  
printing (retracts to the initial print position).

Expanded Printhead Gap  
Your printer can be used for dedicated bottom-feed printing  
on extra-thick multi-part forms. Extra-thick multi-part forms  
range from 0.017-inch (0.43 mm) to a maximum of 0.03 inch  
(0.79 mm). To print on extra-thick multi-part forms, you  
engage the expanded printhead gap feature. This expands the  
head gap settings for extra-thick forms and heavy card stock.  
It also increases the impact strength of the pins in the  
printhead.  
To engage the expanded printhead gap:  
1 Turn the printer off.  
2 Remove the access cover and the pull-up roller assembly.

Problem 1:  
My word processor files do not print the way I have the  
menu and front panel set.  
Solution:  
Solution:  
Always remember that:  
Before sending a file to the printer, many word processors  
send either an “initialization string” or an I-Prime signal to  
the printer.  
1 Settings in your software application will override any  
settings in your printer driver.  
2 Your printer driver settings will override any settings from  
The initialization 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. Refer to “Using  
Your Printer, Menu Mode.”

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. Refer to “Using  
Your Printer, Menu Mode.”

Problem 2:  
Problem 4:  
Nothing happens when I turn on the printer.  
I'm getting strange symbols, incorrect fonts, etc., when I  
try to print a document.  
Solution:  
Solutions:  
Check the power cord connection to the outlet. If you are  
using a power strip, make sure it is turned on, and that a fuse  
hasn’t blown or that a circuit breaker hasn’t tripped.  
1 Check to be sure that the printer driver you have selected  
in your software matches the printer emulation.  
Press SHIFT and SEL keys, then press GROUPkey.  
Problem 3:  
This will print a line showing the emulation you have  
selected.  
The printer does not print when the computer sends  
data.  
2 If you have embedded any printer commands in your  
software, check to be sure that you entered them correctly.  
Solutions:  
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.

Problem 5:  
Problem 7:  
Ink smears on the paper when I print on narrow forms.  
The ALARM light is flashing.  
Solution:  
Solution:  
This may be caused by excessive printhead travel from the  
centering position. Enter the Menu and set the Centering  
Position to MODE 1. Refer to “Using Your Printer, Menu  
Mode.”  
Try turning the printer off and then back on again. If the light  
still blinks, call for service.  
Problem 8:  
The ALARM light is on and the Character Pitch 10 light  
is flashing.  
For the wide-carriage printer, if MODE 1 doesn't work, try  
setting the Centering Position to MODE 2.  
Problem 6:  
Solution:  
I've installed a new ribbon and the printing is smeared  
and streaked.  
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.  
Solution:  
The ribbon shield is either loose or missing. Remove the  
ribbon cartridge and check the ribbon shield.  
If it is loose, secure it.  
If it is missing, find it and install it.

Problem 9:  
Problem 11:  
The ALARM light is on and the Character Pitch 15 light  
is flashing.  
The Print Quality and Character Pitch keys on the front  
panel don't work.  
Solution:  
Solution:  
This indicates a paper jam. Press the SEL key and correct the  
paper jam situation. Refer to “Maintenance, Paper Jams.”  
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.  
Problem 10:  
The printer needs paper, but the ALARM light is not on  
and I cannot load the paper.  
Check with your system manager before changing any menu  
settings.  
Solution:  
Refer to “Using Your Printer, Menu Mode.”  
Press and release the SEL key.  
Problem 12:  
Then, press and hold the SHIFT key and press the RESET  
(CHARACTER PITCH) key.  
Continuous-form paper sticks to the paper separator.  
The printer is reset.  
Solution:  
In cold dry weather, static charges can build up and make the  
paper cling to the paper separator. Try moving the paper  
guides together so that the paper rests on the guides rather  
than on the separator.

Safety Information  
Your OKI printer has been carefully designed to give you  
years of safe, reliable performance. As with all electrical  
equipment, there are a few basic precautions you should take  
to avoid hurting yourself or damaging the printer:  
• To avoid damaging the power cord, do not put anything  
on it or place it where it will be walked on. If the cord  
becomes damaged or frayed, replace it immediately.  
• If you’re using an extension cord or power strip with the  
printer, make sure that the total of the amperes required by  
all the equipment on the extension is less than the  
extension’s rating. Generally, the total ratings of all  
equipment plugged into any one power line should not  
exceed 15 amperes. Don’t exceed this unless you know  
that the power line your equipment is plugged into has a  
rating above 15 amperes.  
• Carefully read all setup and operating instructions. Be  
sure to save all documents for future reference.  
• Read and follow all warning and instruction labels on the  
printer itself.  
• Place your printer on a firm, solid surface. If you put in on  
something unsteady, it might fall and be damaged.  
• Avoid overheating the printer. Do not place it on a soft  
surface, such as a rug, sofa, or bed. The vents may be  
blocked, causing the printer to overheat.  
• Unplug the printer before you clean it. Use only a damp  
cloth. Do not use liquid or aerosol cleaners.  
• To protect your printer from overheating, make sure no  
openings on the printer are blocked. Do not put the printer  
on or near a heat source, such as a radiator or heat register.  
If you put the printer in any kind of enclosure, make sure  
it is well ventilated.  
• The printhead can get quite hot when it has been printing  
for a length of time. Do not touch the printhead until it has  
had a chance to cool off.  
• The printer must be installed near a power outlet which  
will remain easily accessible.  
• Be certain that your power source matches the rating listed  
on the back of the printer. If you aren’t sure, check with  
your dealer or with your local power company.  
Your printer has a grounded, 3-prong plug as a safety  
feature. It will only fit into a grounded outlet. If you can  
not plug it in, chances are that you have an older, non-  
grounded outlet. Contact an electrician to have it  
replaced with a grounded outlet. Do not use an adapter to  
defeat the grounding.  
• Do not use your printer near water. Do not spill liquid of  
any kind into it.  
120

• Do not poke anything into the ventilation slots on the  
sides of the printer. You could get a shock or cause a fire.  
• Aside from the routine maintenance described in this  
document, don’t try to service the printer yourself.  
Opening the cover may expose you to shocks or other  
hazards. Don’t make any adjustments other than those  
outlined in the document. You might cause damage  
requiring extensive repair work.
