Important Safety Instructions
Your OKI printer has been carefully designed to give you years of safe, reliable per-
formance. As with all electrical equipment, however, there are a few basic precau-
tions 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 com-
pany.
• 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 immedi-
ately.

• 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 Chap-
ter 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.
