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 la bels 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 into it.
• Be certain that your pow er 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-prong plug as a safety feature,
and it will only fit into an earthed outlet. If you can not 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 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.
• If you are 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. 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 pr inter;
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 shoc ks or other hazards.
English
• Lifting the top cover exposes hot surfaces. T hese are clearly
labelled. Do NOT touch them.
• Do not make any adjustments other than those outlined in
the handbook 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.
Always use genuine OKI consumables. Some
alternatives can cause serious damage and may affect
your warranty.
This product complies with the requirements of the

Software Problems
Your software (operating environment, applications and printer driv ers) controls the printing process. Make sure you have selected
the right driver for use with your printer. See your software documentation for more information.
Symptom
Printing is “garbled”.
Printer’s output is below rated speed.
Size of top margin increases with each
page printed.
Problem
Incorrect driver is installed.
Much of the printing delays will be caused by
your application. Sometimes, purely text
documents will print slowly depending on the
selected fonts and how they are transferred to
the printer.
“Creeping text.” Number of lines per page in
software is not equal to number of lines per page
of printer.
Solution
Install an appropriate driver.
For maximum speed, use text in your
document and use a printer resident font.
Many software packages assume 66 lines
per page, but your printer’s default is 64.
Adjust software accordingly, or set LINES
Per PAGE in the soft control panel to equal
lines per page in your software.
English

What is a Font?
OKIPAGE 6e/6ex Fonts
A font is a set of letters and other characters with a common
design and style. The OKIPAGE 6e/6ex provide a bitmapped
font which has a specific height and point size. In addition there
are also resident scalable fonts, which you can print in any size
from 4 points to 999.75 points. (1 point = 1/72")
Selecting Fonts in Your Software
The easiest way to select fonts is through your software program.
Your software can send a printer command that consists of a set
of codes, one for each of the font characteristics. If your software
has the appropriate driver, you can specify the font y ou want,
and it will send the necessary commands to the printer. For
detailed information on how to select fonts in your software
package, refer to your software documentation.
These typefaces are resident in the OKIPAGE 6e/6ex:
• 35 MicroType® scalable fonts
• 10 TrueType® scalable fonts
• 1 Line Printer bitmap font
• OCR A/B
The default font is Courier.
To see a sample of the printer’s resident fonts, enter the
Operator Panel
Fonts
, then OK.
. Click on
Se rvice
tab. Under

English
Symbol Sets
Your printer provides special sets of characters for technical,
legal and foreign language uses, as well as sets of drawing
characters and standard alphanumeric characters. Each font uses
symbols from one or more of these sets.
A list of symbol sets is available in the Programmer's Reference
Guide for your printer which is available as a hard copy or on
disk from your OKI dealer.

Toner Cartridge Life
When to Replace the Toner Cartridge
How long your toner cartridge lasts depends on the print density ,
the percentage of the page that prints black. A typical letter has
3% to 5% print density; graphics usually have higher density.
Higher print density means toner is used up faster.
At 5% print density, a toner cartridge will print an average of
2,000 pages. Remember, this is only an average: actual results
may vary.
The first toner cartridge in your ne w printer has to f ill the dr um
reservoir and saturate the developing r oller with toner. It normally
produces about 1,000 pages.
Replace the toner cartridge when you see the TONERLOW
message displayed in your status monitor on the OKIPAGE 6e
or in the message window on your OKIPAGE 6ex. You can
continue printing until print quality deteriorates.
Replacing the Image Drum Cartridge
1.Open the cover and remove the used image drum cartridge.
2.Unwrap the new Image Drum cartridge and remove the
protectiv e sheet.
3.Insert the new Image Drum cartridge.
4.Remove the sponge insert.

tab. Under

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 at one
page per job, 16,000 pages at three pages per job and 20,000
pages at fifteen pages per job. These numbers are approximate,
since you do not print the same number of pages each time, and
environmental conditions and paper type used may vary.
When to Replace the Image Drum Cartridge
When the drum reaches 90% of its life, the Status Monitor on
the OKIPAGE 6e or the message window on the OKIPAGE 6ex
displays CHG DRUM. At this point, be sure you have a new
drum on hand. Replace the old one as soon as the print quality
becomes faint or starts to deteriorate.
