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 printer:
• Read the setup instructions in this handbook 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 may fall and be damaged; if you
place it on a soft surface, such as a rug, sofa, or bed, the
vents may become blocked, causing the printer to overheat.
• To protect your printer from overheating, make sure all
openings on the printer are not blocked. Do not put the
printer on or near a heat source, such as a radiator or heat
register. Keep it out of direct sunlight. Allow enough room
around the printer for adequate ventilation and easy access
to the paper trays.
• Do not use your printer near water, or spill liquid of any
kind on 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 an earthed, 3-pin plug as a safety feature,
and it will only fit into an earthed outlet. If you cannot
plug it in, chances are you have an older, non-earthed
outlet; contact an electrician to have the outlet replaced.
Do not use an adapter to defeat the earthing.
• To avoid damaging the power cable, do not put anything
on it or place it where it will be walked on. If the cable
becomes damaged or frayed, replace it immediately.
• If you are using an extension cable or power strip with the
printer, make sure that the total current (amperes) required
by all the equipment on the extension is less than the
extension’s rating. The total ratings of all equipment plugged
into the outlet should not exceed 15 amperes.
• This printer must be installed near to a power outlet switch
which shall remain easily accessible.
• Do not poke anything into the ventilation slots on the printer;
you could get a shock or cause a fire.
• Aside from the routine maintenance described in this
handbook, do not try to service the printer yourself; opening
the cover may expose you to shocks or other hazards.

• Lifting the top cover exposes hot surfaces. These are clearly
labelled. Do NOT touch them.
• Do not make any adjustments other than those outlined in
the handbook since you may 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 contact your dealer.
These are some of the things to look for:
• The power cable or plug is frayed or damaged.
• Liquid has been spilled into the printer, or it has been
exposed to water.
• The printer has been dropped, or the cabinet is damaged.
• The printer does not function normally when you are
following the operating instructions.
This product complies with the requirements of the Council
Directives 89/336/EEC and 73/23/EEC on the approximation

When to Replace the Toner Cartridge
Replace the toner cartridge when you see theTONER LOW
messagedisplayed on your screen.Youcan continue printing
usingthe tonerin theprinterreservoir. However, you should
replace the toner cartridge as soon as possible to maintain
print quality and avoid possible damage to the imaging
system.
Note: Werecommendthat you use genuine Oki consumable
products in your page printer. Oki’s microfine toner
gives you the ultimate in print quality. Third party
consumables may not give the same performance,
could damage your printer, and may affect the
warranty.
Toner Cartridge Life
How long your toner cartridge lasts depends on the print
density, the percentage of the page that prints black.
Atypical letter has3% to 5%print density; graphicsusually
have higher density. Higher print density means toner is
used up faster.
At 5% print density, a toner cartridge will print an average
of 1,000 pages. Remember, this is only an average: actual
results may vary.
The first toner cartridge in your new printer has to fill the
drumreservoir and saturate the developingrollerwith toner.
The ‘Toner Low’indication will therefore occur earlier than
with subsequent cartridges. This does not mean a reduced
number of pages can be printed from the first cartridge, it
simplymeans that the toner hasbeen transferredto the drum
reservoir.

Cleaning the LED Array
Clean the LED Array:
• Whenever you install a new toner cartridge.
• If you see faded vertical areas or light printing down a
page.
• If printing is fuzzy or blurred.
Wipe the LED array gently with the cleaning pad that came
with your toner cartridge. You can also use a clean, lint
free cloth.

5. Install a new toner cartridge (See page 6).
6. Reset the Drum Counter:
a. Enter the printer status monitor.
b. Click on the Settings tab.
c. Under Reset Item, click Drum Count, Reset.
When to Replace the Image Drum Cartridge
As the image drum approaches its end of life, CHANGE
DRUM displays on your screen. At this point, be sure you
have a new drum on hand. Replace the old one as soon as
print quality becomes faint or starts to deteriorate, or when
the toner cartridge nears empty and the TONER LOW
message displays.
Image Drum Cartridge Life
The life of an image drum depends on a number of factors,
including temperature and humidity, the type of paper you
use, and the number of pages per job.
The image drum cartridge should last about 10,000 pages
for continuous printing, up to 8,000 pages at 3 pages per
job, and about 4,500 pages at 1 page per job.

18 OKIPAGE 4m/4w Plus
Problem: Printed paper curls excessively.
Solution: Heat from the toner fusing process removes
moisture from paper and may cause curling.
If curling is severe:
(a) Turn paper over in the paper feeder. Put
paper in feeder with print facing the back
of the printer, look on the package for an
arrow or other indicator of the print side.
(b) A major cause of curl is improper storage.
Store paper in a dry place, lying flat. Do
not open the paper package until you are
ready to use the paper.
(c) Try to protect your paper from excessive
temperatures and rapid temperature
changes.
Problem: Printer seems too hot.
Solution: The toner fusing process in your printer
generates a significant amount of heat, and the
topcoverwillfeelquite warm.This isperfectly
normal. If the top cover becomes too hot to
touch, switch the printer off and call your
dealer for advice.
Problem: Printed paper emerges wrinkled.
Solution: Use the printer control panel software to
change the paper thickness setting to light.
