User’s Guide 1
Safety instructions
This printer has been carefully designed to give years of
safe, reliable performance. As with all electrical equip-
ment, however, there are a few basic precautions that
should be taken to avoid personal injury or damaging
the printer:
• Read this user’s guide carefully and save it for
future reference.
• Read and follow all warning and instruction
labels on the printer itself.
• Disconnect the printer before cleaning. Use only
a damp cloth. Do not use liquid or aerosol clean-
ers to clean the printer.
• Place the printer on a firm, solid surface. If the
printer is placed on something unsteady, it may
fall and become damaged or injure someone. If
the printer is placed on a soft surface, such as a
rug, sofa, or bed, the vents may become blocked
causing the printer to overheat.
• 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.
• Do not use the printer near water, or spill liquid
of any kind into it.
• Make sure that the power source matches the rat-
ing listed on the back of the printer. If you are not
sure, check with your dealer or with your local
power company.
• This printer has an earthed plug as a safety fea-
ture and will only connect to an earthed outlet. If
this plug cannot be connected to a power outlet,
then it is possible that the power outlet is of the
older, non-earthed type. Contact an electrician to
have the power 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 an extension cable or power strip is being used
with the printer, make sure that the total of the
amperage rating required by all the equipment is
less than the rating of the extension cable or
power strip. The total ratings of all equipment

2OKIPAGE 8w Lite
plugged into the outlet should not exceed 13
amperes.
• The power outlet into which the printer is con-
nected must remain accessible at all times.
• Opening any cover may expose hot surfaces.
These are clearly labelled. Do NOT touch them.
• Do not insert 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 user’s guide, do not try to service the printer
yourself. Opening a cover may expose you to
shocks or other hazards.
• Do not make any adjustments other than those
outlined in this user’s guide as damage may be
caused to the printer.
If anything happens that indicates that the printer is not
working properly or has been damaged, disconnect the
printer from the power source 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 fol-
lowing the operating instructions.

Toner cartridge and image drum
handling
• Leave unused toner cartridges and image drum
units in their packages until needed. When
replacing a toner cartridge or image unit, reuse
the packaging to dispose of the old toner cartridge
or image drum unit.
• Do not expose the toner cartridges and image
drum units to light for more than five minutes.
Never expose the green drum (inside the image
drum unit) to direct sunlight.
• Always hold the image drum unit by the ends —
never by the middle. Never touch the green drum
inside the image drum unit.
• To avoid damage to the image drum unit, always
use original toner cartridges.
• Exercise care when removing the toner cartridge.
Do not let it touch your clothing or porous mate-
rials. The toner powder causes permanent stains.
• Small amounts of toner spilled on skin or cloth-
ing can be readily removed with soap and cold
water. Using heated water will make removing
the stain much more difficult.
Emergency first aid
•IF TONER IS SWALLOWED: Induce vomit-
ing and seek medical attention. Never attempt to
induce vomiting or give anything by mouth to a
person who is unconscious.
•IF TONER IS INHALED: Take the person to an
open area for fresh air. Seek medical attention.
•IF TONER GETS IN THE EYES: Flush eyes
with large quantities of cool, NOT cold, water for
a minimum of 15 minutes keeping eyelids open
with fingers. Seek medical attention.

Paper
Paper and envelope types
The manufacturer of this printer recommends the fol-
lowing guidelines when selecting paper and envelopes
for use in your printer:
• Paper and envelopes should be stored flat and
away from moisture, direct sunlight and heat
sources.
• Use a smooth finished paper such as copier or
laser type paper with a Sheffield (smoothness)
rating of 250 or less. If in doubt, please ask your
paper supplier.
• Use envelopes designed for use in laser type
printers.
• The use of heavily laid or textured paper will
seriously impact on the life of the image drum.
• Do not use very smooth, shiny/glossy paper.
• Do not use heavily embossed headed paper.
• Avoid printing on both sides and putting paper
through the printer twice.
• Avoid using paper with perforations, cut outs and
ragged edges.
• Do not use envelopes with windows or metal
clasps.
• Do not use envelopes with self sealing flaps.
• Avoid using damaged or curled envelopes.
Transparencies and adhesive labels
The manufacturer of this printer recommends the fol-
lowing guidelines when selecting transparencies and
adhesive labels for use in your printer:
• Always use manual feed.
• Media must designed for use in laser printers or
photocopiers. Do not use media designed for use
in colour laser printers and photocopiers.
• Must be able to withstand 200°C for 0.1 sec.
• Labels should cover entire carrier sheet.
• Carrier sheet or adhesive must not be exposed to
any part of the printer.

User’s Guide 5
Loading paper
1. Set the left paper guide to the marker for the
required paper size and move the right guide to a
position slightly wider than your paper width.
2. Insert the paper so that it is up against and flush
with the left paper guide.
3. Adjust the right paper guide to fit snugly, but not
tightly against the edge of the paper.
4. Lift the paper slightly out of the tray (about 1 cm)
and allow it to drop back into place under its own
weight. Do not force it down.
Note:
If using letterhead paper, insert the letterhead
face down with the top first.
Manual feed
Use manual feed for envelopes, transparencies and
other print media as follows:
1. Adjust the paper guides (1) to the width of the
media being used.
2. Insert the media squarely into the paper guides to
prevent skewing.
Note:
Insert envelopes with flap side down and to the
left. Insert letterheaded paper face up with top
of page first.
Paper output
Up to 30 sheets of paper (75 g/m2) can be stacked in the
output tray and the printed pages exit from the printer
face up.

Print quality adjustments
The process used to fuse (fix) the printed image to the
paper involves a mixture of pressure and heat. Too
much heat will cause lightweight paper to crease or curl
and corrugations in transparencies. Too little heat will
cause the image not to fuse fully into heavyweight
paper.
The print quality for different types of paper is set by
default according to the paper size. If thinner or thicker
paper is being used, the thickness setting can be adjust-
ed as follows:
The settings for the various types of paper are given in
the following table
Macintosh Windows Paper Weights
Thickest Heavy Postcard, envelope, OHP, labels,
thick paper more than 90 g/m2
Thicker Medium heavy Approx. 90 g/m2
Thick Medium Approx. 75 to 90 g/m2
Normal Medium light Approx. 55 to 75 g/m2
Thin Light Approx. 55 g/m2

Toner
When to replace toner cartridge
After the message Toner Low displays, the printer will
print about 100 more pages, then display the message
Toner Empty and stop printing. Printing will resume af-
ter a new toner cartridge has been installed.
CAUTION:
The use of original toner or toner cartridges is highly
recommended. Using compatible or counterfeit toner or
toner cartridges can seriously damage the printer.
Toner cartridge life
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 den-
sity means toner is used up faster. At 5% print density,
a toner cartridge will print an average of 1500 pages.
Remember, this is only an average: actual results may
vary.
The first toner cartridge installed in a new printer has to
fill the image drum reservoir and saturate the develop-
ing roller with toner. The first toner cartridge normally
produces between 500 and 700 pages after installation.

Image drum
When to replace image drum
As the image drum approaches its end of life, a Change
Drum message appears. Change the image drum when
the print quality becomes faint or begins to deteriorate.
Image drum life
The life of an image drum depends on a number of fac-
tors, including temperature and humidity, the type of
paper used, and the number of pages per job.
The image drum should last about 10,000 pages contin-
uous printing and up to 8,000 pages at 3 pages per job
(without power save). These numbers are approximate
because different number of pages are printed each time
and the environmental conditions and the paper type
used may vary.
Replacing image drum
1. Open the cover and remove the used image drum.
CAUTION:
Never expose the image drum unit to light for more than 5
minutes. Never expose the image drum unit to direct
sunlight. Always hold the image drum unit by the ends.
Never touch the surface of the green drum inside the image
drum unit.
2. Remove the new image drum from the package
and remove the protective sheet (1) from the
image drum (2).
3. Install the new image drum (1) into the printer
placing the alignment pins on each end into the
slots in the printer.

Fonts
What is a font?
A font refers to a set of printable characters in a partic-
ular typeface of a specific size (e.g. 12 point) and style
(e.g. roman, bold or bold-italic). In computer printing,
however, this term has been used in a wider context to
refer to all sizes and styles of a particular typeface. In
printers, fonts may be divided into two basic types: bit-
map fonts and scalable (or outline) fonts.
Bitmap fonts are made up of a pattern of dots (at the
printer resolution) to form the image of each printable
character. These are of a fixed size and scaling makes
them look ragged.
Scalable fonts are stored as a set of mathematical
curves. At print time, the printer uses the stored curves
to make up a bitmap of each character required, at the
required size in the required style, at the full printer res-
olution. Such fonts are therefore said to be scalable and
do not appear ragged at enlarged sizes.
Using fonts
The easiest way to select fonts is through the software
program being used. Software programs send printer
commands that consist of a set of codes, one for each of
the font characteristics. If the software program has the
appropriate driver, fonts can be specified and the neces-
sary commands will be sent to the printer. For more de-
tailed information on how to select fonts in a software
program, refer to the documentation for that software
program.
