Important Safety Instructions
• 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.
• 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.
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:
• 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.
• The printer must be installed near a power outlet which
will remain easily accessible.

|Safety4
• 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.
• 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.
• Do not use your printer near water. Do not spill liquid
of any kind into it.
• 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.
• If anything happens that indicates that your printer is
not working properly or has been damaged, unplug it
immediately and have your printer serviced.
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.
