ImportantSafety Instructions
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:
• Read the setup and operating 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
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.
• 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, 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 are not sure,
check with your dealer or with your local power
company.
• 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; have an electrician
replace it with a grounded outlet. Do not use an
adapter to defeat the grounding.
• The printer must be installed near a power outlet
which remains easily accessible.
• 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.
E-ii
• 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 exten-sion’s rating. Generally, the total
ratings of all equipment plugged into any one power
line should not exceed 15 amps. Don’t exceed this
unless you know that the power line your equipment
is plugged into has a rating above 15 amps.
• 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. the
Warranty, Regulatory, and Safety Information booklet
supplied with your printer explains how to get your
printer serviced by qualified Okidata technicians.
• If anything happens that indicates that your printer is
not working properly or has been damaged, unplug it
imme-diately and follow the procedures in the
Warranty, Regulatory, and Safety Information booklet
supplied with your printer for having your printer
serviced.
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.
