Important Safety Instructions
Your OKI printer has been carefully designed to give you years of safe, reliable performance. As with all electrical equipment, however, there are a few basic precautions
you should take to avoid hurting yourself or damaging the unit:
• Read the setup and operation instructions in this manual carefully. Be sure to
save it for future reference.
• Read and follow all warning and instruction labels on the printer itself.
• Unplug the printer before you clean it. Use only a damp cloth; do not use liquid
or aerosol cleaners.
• Place your printer on a firm, solid surface. If you put it 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.
• To protect your printer from overheating, make sure no openings on the printer
are blocked. Don’t 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.
• Do not put anything into the ventilation slots on the sides of printer, you could
get a shock or cause a fire.
• The printhead can get quite hot when it has been printing for a length of time.
Do not touch the printhead untill it has had a chance to cool off.
• Do not use your printer near water, or spill liquid of any kind into it.
• Be certain that your power source matches the rating listed on the back of the
printer. If you’re not sure, check with your dealer or with your local power company.
• Your printer has a grounded plug as a safety feature, and it will only fit into a
grounded outlet. If you can’t plug it in, chances are you have a non-grounded
ontlet; 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, don’t 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.
• Aside from the routine maintenance described in this handbook, 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
manual – you might cause damage requiring extensive repair work.
• If anything happens that indicates that your printer is not working properly or
has been damaged, unplug it immediately and follow the procedures in Chapter 5. These are some of the things to look for:
The power cord or plug is frayed or damaged.
Liquid has been spilled into the housing, or the printer has been exposed to
water.
The printer has been dropped or its cabinet has been damaged.
The printer doesn’t function normally when you’re following the operating
instructions.

Your printer has provision for single-sheet paper feed from the top and for continuous-form paper feed from the rear. You can also install options: the Cut Sheet Feeder,
which holds a stack of 100 sheets for feeding from the top and the Push and/or Pull
Tractors for feeding continuous-form labels, heavy card stock or multi-part forms from
the bottom. See Chapter 5 for more information on these options.

12 Loading Paper
Loading Single-Sheet Paper
The single-sheet paper path is best for letterhead stationery, memos, and envelopes.
We also recommend it for printing graphs and charts because it provides the most
accurate control of the paper.
To load in single sheets of paper:
If you have any continuous-form paper in the paper path, you must press the
PARK button on the front panel to remove it from the path before lading single
sheets.

Loading Rear-Feed Paper
The rear-feed paper path is recommended for single-thickness, continuous fan-fold
paper when printing spreadsheets, long reports, etc. For graphics or charts, it’s best to
use the single-sheet paper path.
To load continuous-form paper from the rear:
1. If you have paper in paper path, be sure
to remove it before installing rear-feed
paper. To remove single sheet, press FF/

Paper Handling
Your printer has several handy paper handling features:
• Tear
• Form Tear-off
• Paper Park
Tear Feature
When you’re using continuous forms with either the built-in rear-feed tractor or the
optional bottom-feed push tractor, you can use this feature to advance the forms up to
the tear position so you can easily tear off a printed sheet without wasting paper or
readjusting the printer. To do this, simply press the TEAR button on the front panel.

Forms Tear-off Feature
Caution!
Do not engage Forms Tear-off when printing on labels!
The Forms Tear-off feature can be engaged to automatically move the paper up to the
tear position after the selected interval (500 milliseconds, one second, or two seconds).
The page will stay in the tear-off position until the printer receives data. It will then
move down to the initial printing position.
This feature is normally turned off. To activate it, enter the printer menu (see Menu
Mode in Chapter3) and choose one of the intervals.
Some programs, such as high resolution graphics packages, pause occasionally while sending data to the printer. If the pause lasts more than the selected
interval, the paper will advance to the rear-off position until more data is
received. No data will be lost, but this extra paper movement can cause uneven print registration in graphics. If you have this problem, use the menu to
deactivate Forms Tear-off.
Paper Park Feature
If you have continuous-form paper loaded and you wish to switch to another paper
path, first tear off the printed pages, then simply press the PARK button. The continuous-form paper will immediately retract from the paper path.

1. Tear off printed pages.
2. Press PARK button.
3. Swing wire guide up into paper separator, then pivot separator to upright position.
4. Move paper lever to position marked “TOP”.
5. Load single sheet paper into paper separator.
To switch from top feed to continuous-form tear or bottom (optional push or pull
tractor installed) feed:
1. Make sure no sheet is in paper path (press FF/LOAD to remove single sheet from
path).
2. Lower paper separator to continuous forms position and swing wire guide over
onto pull-up roller assembly.
3. Move paper lever to position marked “REAR” or “BOT”, as appropriate.
4. Press FF/LOAD button. Continuous-form paper will advance into print position.
