Safety
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:
•
•
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 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.
•
•
•
•
Read the Setup Guide carefully. Be sure to save it for future
reference.
Read and follow all warning and instruction labels on the
printer itself.
•
•
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.
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.
If you are using an extension cable 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 13 amperes.
•
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.
•
•
•
The power outlet into which you plug your printer must
remain accessible at all times.
Lifting the top cover exposes hot surfaces. These are clearly
labelled. Do NOT touch them.
Do not poke anything into the ventilation slots on the printer;
you could get a shock or cause a fire.
•
Do not use your printer near water, or spill liquid of any
kind into it.
OKIPAGE 8c Plus

•
•
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.
Always contact your local dealer.

Viewing and Using Menu 1 & Menu 2
Operator Panel Menus
To display a menu, press the ON LINE key to take the printer
OFF LINE.
The keys on the operator panel and the LCD display provide a
means of controlling the operation of your printer. There are
two main menus: Menu 1 and Menu 2.
To enter Menu 1, press and release the MENU 1 / Menu 2 key.
The first category in Menu 1 will be displayed on the top line.
Each menu is organised into three levels: Categories, Items and
Settings.
To enter Menu 2, press and hold for more than 2 seconds the
MENU 1 / Menu 2 key. The first category in Menu 2 will be
displayed on the top line.
Categories divide the menus items up into related groups, or
topics. These appear on the top line of the display.
To advance through the available categories in either menu, press
and release the MENU 1 / Menu 2 key. When the last category
is displayed, pressing the MENU 1 / Menu 2 key again returns
to the first category.
When the required category is selected, the top line changes to
show the current menu item.
When the item is displayed in the top line, the current setting
for that item is displayed in the bottom line. Each menu item
has two or more settings associated with it.
To select a category and view the items in that category, press
and release the ENTER key when the required category is
displayed.
The currently active setting also displays the asterisk (*)

to the ON LINE (ready) condition.
Viewing and Using the User Maintenance Menu
The tables on the next several pages detail all menu items and
the available settings, and explain how these settings control
the operation of your printer.
This is a special menu used for functions, such as disabling or
enabling the operator panel controls.
The user maintenance menu is organised in two levels: Items
and Settings.
To enter this menu you must first switch the printer off.
Whenever you switch the printer off, it is a good idea to wait for
at least ten seconds before switching it on again, to ensure that
memory contents are properly cleared and internal power
supplies are allowed to settle.
Hold down the MENU 1 / Menu 2 key and switch the printer
on.

Adjusting Colour Registration
Each of the four image drums is responsible for producing that
part of the printed image corresponding to its particular colour.
The three primary colours and black are mixed in various
proportions to obtain other colours.
3. Press the ENTER key. The display will show
INITIALIZING for a few seconds and then PRINT
PATTERN.
After a short delay the registration test pattern will emerge.
Of course, it is essential that each image drum cartridge produces
its part of the printed image at exactly the right place on the
page relative to each of the others. If one cartridge, for example
yellow, is slightly misaligned you will notice slight traces of
yellow at the edges of other colours where yellow should not
appear. This very precise alignment is known as colour
registration.

Although this page at first appears complicated, upon
examination you will see that it actually has 9 areas which
are virtually identical. There are three adjustments for each
colour, and these adjustments are simply repeated. The
whole process should take no more than about 10 minutes.
The rest of the 9 settings are similar. Although this may at
first seem a little complicated, by the time you have
completed 2 or 3 settings it will become fairly a simple and
straight forward procedure to adjust colour registration.
You may find colour registration adjustment quicker and
easier if you examine all nine areas first, making a note in
each area of the test pattern of any numerical adjustment
needed (simply write nothing in the areas which do not
need adjustment). You can then speed through the nine
adjustments, entering the values you have noted.
Each area shows boxed sections, most of which have some
colour inside them. Ideally, the centre boxes — those
corresponding to the numbers +2 to –2 should be almost
free of colour, like the box shown by itself, which contains
no colour at all.
Once the test pattern has appeared the printer displays
ADJUST #1 ready for adjustment. This relates to area 1 on
the test pattern.

Adjusting Colour Balance
Your printer uses three primary colours plus black mixed in
appropriate proportions to print images in a wide range of
colours. The relative density of each primary colour determines
the actual colour printed. This property is known as colour
balance.
6. Press the ENTER key to print a new test pattern and
compare the results.
You may need to repeat the 9 adjustments 2 or 3 times to
achieve accurate alignment, since they are interdependent.
However, the whole process can be completed in about 10
minutes, and should not often need readjustment.
Although the printer and its consumables are all manufactured
to very high standards of precision, very small variances in
manufacture, as well as variations in paper composition and
printing environment, can cause minor shifts in colour balance
to occur from time to time.
You can easily make fine adjustments to colour balance using
the operator panel controls on your printer. Your printer has a
built-in test pattern to help you.
Since colour balance is affected by the particular paper
you will print on, you should load that paper type before
making these adjustments.
1. Press the ON LINE key if necessary to take the printer
OFF LINE.
2. Press and hold the MENU 1 / Menu 2 key until the message
COLOR REG ADJUST appears in the display panel, then
release the button.

5. Examine each of the coloured circles carefully to determine
which one is most closely matched in colour to the large
area A, then make adjustments as described in the next step.
4. Press the ENTER key. After a short delay the colour balance
test pattern will emerge, and the printer will enter its
adjustment mode.
6. Each primary colour and its current setting is displayed in
turn. Use the ← or → keys to increase or decrease the setting
if required, then press the ENTER key to enter it. An asterisk
(*) will appear in the display.
The test pattern contains a large rectangular area marked A

Fonts
Scalable Fonts
Your printer supports both bitmapped and scalable fonts in a
wide range of character sets for use in a number of European
languages.
These are stored as outline curves represented by mathematical
formulae, and may be scaled larger without loss of print
resolution.
You can see a list and printed examples of all the fonts resident
in the printer by printing a font list.
When scalable fonts are used in a document a temporary bit
map of each character is created in a special part of the printer’s
memory called the font cache. This bit map is produced at the
full operating resolution of the printer, either 300 or 600dpi,
depending on which is currently selected, so no jagged edges
are apparent.
To print the font list:
1. Press the ON LINE key to take the printer OFF line.
2. Press and hold the Print Fonts key for more than 2 seconds,
then release. Press the ← or → key to select PCL5c or Adobe
Postscript fonts and then press the ENTER key. After a
short delay a list of all the selected fonts, together with
examples of what they look like, will emerge.
Examples of resident scalable fonts are Courier, CG Times and
Univers. There are many other resident fonts stored in your
printer, as you will see when you print the font list.
Using Fonts in Windows Applications
If you run Windows on your computer you will be familiar with
the selection of different fonts within your documents.
Bit Mapped Fonts
These are character shapes stored as a collection of dots (bits).
They are stored in a fixed size. If you print enlarged versions
you will see jagged edges around the characters, due to the
enlarged dots.
Most Windows applications use TrueType fonts, a scalable font
technology pioneered byApple Computer Corp. Most TrueType
fonts in Windows documents will download to the printer
automatically as they are required. However, if you choose the
printer’s resident fonts, your documents will generally print
faster and use less printer memory.
Examples of resident bit mapped fonts are LinePrinter, OCR-
A, OCR-B and UPSZIP (bar codes).

Paper & Other Print Media
Dealing With Paper Jams
Your printer is capable of high quality output on various media
types. For most general purpose office applications normal 80g/
m² copier paper is adequate. However, for better print quality a
high grade paper recommended for laser printing will give better
image definition and contrast, as well as brighter, more vibrant
colours.
Your printer should give years of reliable service, handling a
range of print media (paper, transparencies, etc.) with few
problems. However, paper jams may occur from time to time,
due to excess humidity, damaged paper (for example, torn or
bent corners), or minor malfunction.
Paper jams will be indicated on the operator panel display, the
printer will stop, and the ATTENTION light will illuminate.
Heavily textured or embossed paper stock will generally give
poor results, because it is difficult to effectively transfer a toner
image to such materials and then fuse it properly.
A paper jam does not always mean that paper is physically
jammed. It simply means that paper has been detected where it
should not be at that time, or no paper has been detected where
there should be paper at that time.
Transparencies may be used for overhead projectors, but these
must be of the type intended for use in laser printers or copiers.
They must be able to withstand the high temperatures generated
by the fuser, and should not be of the type with removable
backing paper or edging strip.
Paper Input Jam
Paper Feed Jam
Paper Exit Jam
Paper has jammed between the paper tray
and the first image drum.
Paper has jammed after the first image
drum and before the fuser.
On no account use transparencies intended only for
marking directly with marker pens. These will melt and
cause extensive internal damage to your printer.
Paper has jammed in the fuser or between
the fuser and the point of exit.
OKIPAGE 8c Plus
26
Standard Paper Path
On leaving the fuser, the paper passes via two pairs of exit pinch
rollers (6) and on to the paper stacker on top of the printer or the
rear stacker if it is open.
The illustration (looking into the left-hand side of the printer)
here shows the paper path through the printer.
Gaining Access to the Paper Path
Access to the paper entry area is via the front feeder unit (7).
Access to the paper exit (post fuser) area is via the rear stacker
(8). Access to the paper feed area is via the top cover.
Front Feeder and Rear Exit Paper Path
When feeding heavy print media it is advisable to use the front
feeder and rear stacker to keep the paper path as straight as
possible.
Paper is normally fed from the paper tray (1), through the paper
entry pinch rollers (2), and onto the transfer belt (3). It is held
against the transfer belt by an electrostatic charge.
Paper enters from the front feeder into the front pinch rollers
(2), and travels on to the transfer belt in an almost straight line.
As the belt rotates (anti-clockwise in this view), the paper passes
under each of the four image drums (4), where the toner image
is transferred to the paper and held there lightly by electrostatic
charge.
On leaving the fuser assembly the paper emerges out through
the open rear exit face upwards.
The paper then moves on to the fuser assembly (5), where the
image is made permanent by a mixture of heat and physical
pressure.
User’s Guide
27
Clearing a Paper Input Jam
Clearing a Paper Feed Jam
A paper input jam indication means paper has jammed between
the tray and the first image drum cartridge.
If paper jams between the first image drum and the fuser it will
be necessary to open the top cover. There is no electrical shock
hazard, since this area is protected by interlocks, so power may
be left on during this operation.
1. Open the front feeder (1) by lifting the latch (2) and pulling
the cover out and downwards.
When accessing the central area take care not to touch
the hot surfaces around the fuser. These are clearly
marked with yellow warning labels, and are very hot.
1
2
When removing image drums, keep them away from
strong light, especially direct sunlight. If in doubt, place
them in their black lightproof bags (supplied with the
printer and with new drums).
3
2. Remove any paper visible in this area.
1. Press the OPEN button and lift the top cover to its fully
upright position.
If paper has advanced up to the first image drum and resists
pulling, clear it as for a paper feed jam, described in the
next procedure.
2. Lift out each of the four image drum cartridges (1) complete
with their respective toner cartridges still in place.
3. Pull out the paper tray (3) and remove any partially feed
sheets.
4. Check that the paper in the tray is stacked neatly, with no
sheets bent or stuck together.
1
5. Push the tray in gently. A full tray is heavy and can damage
the printer if slammed shut.
OKIPAGE 8c Plus
28
Clearing a Paper Exit Jam
Put the drum cartridges where they will not be scratched
and not exposed to strong light.
An indicated paper exit jam means paper has jammed in the
fuser or between the fuser and the point of exit from the printer.
3. Inspect the paper path for sheets of paper. Carefully remove
any sheets (2) you find.
1. Press the OPEN button and raise the top cover to its fully
upright position.
When accessing the central area take care not to touch
the hot surfaces around the fuser. These are clearly
marked with yellow warning labels, and are very hot.
2
2. Push the two coloured fuser latch levers (1) away from you
(towards the rear of the printer).
Paper jammed under the first image drum should be pulled
forwards through the paper path if possible, not backwards,
to avoid spillage of unfused toner into the paper input
area.
2
2
Be especially careful not to scratch the transfer belt.Avoid
using sharp instruments.
1
1
4. Lower each image drum cartridge back into position via its
two locating slots at each side of the printer, being careful
to match the coloured label on each cartridge with its
corresponding coloured label in the printer.
3. Lift the fuser by its two handles (2) straight up and out of
the printer.
5. Close the top cover and press down firmly at both sides to
ensure that it is locked down.
User’s Guide
29
4. Pull out the sheet of paper from between the fuser rollers.
8. Close the rear exit stacker (unless you intend to use it for
the remainder of the print job).
9. Check for and clear any paper feed jams or paper input
jams, as described in the preceding sections.
10. Close the top cover and press down firmly to latch it down.
The print process will resume automatically when you close
the top cover, after a short period to allow the fuser to warm
up again.
5. Lower the fuser back into the printer, press down firmly to
locate, then pull on the two latch levers to ensure the fuser
is locked in position.
6. Open the rear exit stacker (3).

Replacing Toner Cartridges
Your printer uses four toner cartridges: one each for cyan,
magenta, yellow and black. If purchasing less than a complete
set, ensure you are purchasing the colour you require. This is
clearly indicated on the box.
3. Do not attempt to clean spilled toner with any solvent or
spirit-based solution, as this may partially dissolve the toner
and cause permanent marking.
4. Take the new cartridge out of its box before you remove
the old one. The new cartridge comes with a plastic bag
which can be used to wrap the old cartridge for disposal.
Always use genuine OKI consumables with your printer.
These come in the familiar OKI red and white boxes and
are designed and manufactured specially for use in OKI
printers.
5. Do not smoke while changing the toner cartridge. If you do
accidentally cause a toner cloud, as with all fine particle
clouds, it could become flamable.
Genuine OKI toner is made from non-toxic materials and is
perfectly safe to use, provided you follow a few basic safety
rules.
When to Change a Toner Cartridge
1. When removing old toner cartridges from your printer you
will see the toner powder on top of the image drum cartridges.
Take care to avoid performing this task in a draft, and do not
blow on the powder, as this may cause a toner cloud. If you
inhale such a cloud, seek a clean fresh air environment, and
take a few deep breaths. If you continue to experience any
discomfort seek medical advice.
The printer will display a message when any toner cartridge is
within about 100 pages of the end of its life. The display will
also indicate which colour is running out. You can normally
expect a toner cartridge to produce about 3000 pages at 5% print
density (this is a typical density for text pages).
There is no hard and fast rule, since toner life depends very much
on image content. Also, when installing a new image drum, the
first toner cartridge will run out more quickly, because the drum
reservior must fill when new.
2. If you spill any toner on your skin or clothes, brush it off. If
necessary, rinse in cold water. Do not use hot water, since
the application of heat might make the marks permanent.
User’s Guide
31
Replacing a Toner Cartridge
1. Press the OPEN button and raise the top cover to its fully
upright position.
5. Gently shake the new cartridge from side to side to evenly
distribute the toner along its length.
2. Identify by the coloured label (1) which toner cartridge you
intend to remove.
6. Peel off the white adhesive tape seal from the underside of
the toner cartridge.
3. Unlock the cartridge by pulling the coloured lever (2) at
the right-hand end towards you.
1
7. Holding the cartridge with the coloured lever (3) to the right
and the white end cap (4) to the left, lower the toner cartridge
into the top of the image drum cartridge, white cap end
first, then press gently down on the other end to locate the
cartridge firmly onto the image drum cartridge.
2
4. Lift the right-hand end of the cartridge away from the image
drum, and then lift the cartridge out of the machine. Wrap
it for disposal in the plastic bag supplied with the new
cartridge.
4
3
Do not force the toner cartridge into position. It is fitted
with a lock-out mechanism to prevent insertion into the
wrong image drum cartridge.
OKIPAGE 8c Plus
32
8. Push the coloured locking lever (3) away from you (towards
the back of the printer) to lock the cartridge home and
release the toner supply.
Replacing Image Drums
There are four image drums in the printer, one each for cyan,
magenta, yellow and black. If purchasing less than a complete
set, ensure you are purchasing the colour you require. This is
clearly indicated on the box. These are delicate units and should
be handled with care.
3
Always use genuine OKI image drums with your printer.
These come in the familiar OKI red and white boxes and
are designed and manufactured specially for use in OKI
printers.
Cleaning the LED Arrays
Before closing the printer cover, the LED arrays should be
cleaned, using the paper towel in the sachet supplied with the
new toner cartridge. After cleaning, avoid touching these arrays
with your fingers.
The green surfaces of the drums are light sensitive and should
not be exposed to strong ambient light, and especially not direct
sunlight.
1. Gently wipe clean each of the four LED arrays under the
printer top cover.
The green drum surfaces are easily scratched, and should not
be put down where they might come into contact with hard or
abrasive materials. If removed from their packaging, or from
the printer, for more than a few moments, they should be wrapped
in their black, lightproof plastic bags.
2. Close the top cover and press down firmly at both side to
latch it down.
User’s Guide
33
It is essential that each drum be installed in its correct position
in the printer, corresponding with the appropriate coloured label
inside the printer. Each drum assembly is marked with a similar
coloured label for ease of identification.
Changing a Drum Cartridge
Since the toner cartridge should also be replaced at the same
time, the image drum may be removed with the old toner
cartridge still in place.
1. Switch off the printer main power.
When to Change a Drum Cartridge
The printer will display a message when any drum cartridge
needs to be replaced. The status lights on the operator panel
will indicate which drum to replace.
2. Press the OPEN button and raise the top cover to its fully
upright position.
3. Identify by coloured label which drum you intend to replace.
You can normally expect a drum cartridge to produce about
12,000 pages.
Also, when installing a new image drum, a new toner cartridge
should also be installed with it. This toner cartridge will run out
more quickly than normal, because the drum reservoir must fill
when new.
4. Grip the top of the drum assembly and lift it straight up and
out of the printer.
OKIPAGE 8c Plus
34
5. Unpack the new drum cartridge and pull out the protective
sheet of paper.
Resetting Drum Count
After installing a new image drum the page counter for that drum
should be reset. This is performed using the User Menu.
