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:

• 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.

• 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 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.

• 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 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.

• 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.

4

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.

• 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.

Operator Panel Menus

Viewing and Using Menu 1 & Menu 2

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.

Each menu is organised into three levels: Categories, Items and
Settings.

Categories divide the menus items up into related groups, or
topics. These appear on the top line of the display.

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.

The currently active setting also displays the asterisk (*)
character.

Note: Tray 2 only appears in Menu 1/Menu 2 if the
optional Tray 2 is fitted to the printer.

To display a menu, press the ON LINE key to take the printer
OFF LINE.

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.

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.

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.

To select a category and view the items in that category, press
and release the ENTER key when the required category is
displayed.

To advance through the menu items, press the MENU 1 /
Menu 2 key repeatedly until the required item is displayed.
When the last item is displayed, pressing the MENU 1 / Menu 2
key again advances to the next category.

Viewing and Using the User Maintenance Menu

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.

Continue holding down the MENU 1 / Menu 2 key until the
menu name (USER MNT) appears.

Press and release the MENU 1 / Menu 2 key to cycle through
the available items. When the item you require is displayed,
press the ENTER key to select it.

Some user maintenance menu items can be exited by pressing
the ON LINE key to return the printer to the ON LINE (ready)
condition. However, to exit from some other items you will need
to switch the printer off and back on again. (Remember to wait
at least ten seconds before restoring power.)

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 setting applies to PostScript operation only (when
installed). It determines how long the printer will wait for
a sheet to be inserted in the manual paper feeder.

When this function is active, power to the fuser is turned
off to conserve energy. A slightly longer delay will occur
before the next job prints, to allow the fuser to warm up
again.

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.

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.

If you notice any symptoms like that described above, you can
easily correct colour registration using the operator panel controls
on your printer. These adjustments align the three colour
cartridges precisely to the black cartridge. Your printer has a
built-in test pattern to help you.

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.

3. Press the ENTER key. The display will show

INITIALIZING for a few seconds and then PRINT

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.

whole process should take no more than about 10 minutes.

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.

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.

Once the test pattern has appeared the printer displays
ADJUST #1 ready for adjustment. This relates to area 1 on
the test pattern.

4. Examine area #1 on the test pattern closely and identify
which of the numbered boxes contains no colour (or which
contains the least colour). That number is the setting which
should be entered on the printer menu. Use the
keys to increment or decrement the setting if a number other
than 0 is required. When the display shows the number you
want, press the ENTER key to enter it. An asterisk (*) will
appear in the display.

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.

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.

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.

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.

You can see a list and printed examples of all the fonts resident
in the printer by printing a font list.

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
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.

→ →

← or

→ key to select PCL5c or Adobe

←←

→ →

These are stored as outline curves represented by mathematical
formulae, and may be scaled larger without loss of print
resolution.

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.

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

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.

Examples of resident bit mapped fonts are LinePrinter, OCR­A, OCR-B and UPSZIP (bar codes).

User’s Guide 21

If you run Windows on your computer you will be familiar with
the selection of different fonts within your documents.

Most Windows applications use TrueType fonts, a scalable font
technology pioneered by Apple 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.

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.

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.

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.

On no account use transparencies intended only for
marking directly with marker pens. These will melt and
cause extensive internal damage to your printer.

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.

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.

Paper Input Jam Paper has jammed between the paper tray

and the first image drum.

Paper Feed Jam Paper has jammed after the first image

drum and before the fuser.

Paper Exit Jam Paper has jammed in the fuser or between

the fuser and the point of exit.

26

OKIPAGE 8c Plus

Standard Paper Path

The illustration (looking into the left-hand side of the printer)
here shows the paper path through the printer.

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.

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.

The paper then moves on to the fuser assembly (5), where the
image is made permanent by a mixture of heat and physical
pressure.

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.

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 enters from the front feeder into the front pinch rollers
(2), and travels on to the transfer belt in an almost straight line.

On leaving the fuser assembly the paper emerges out through
the open rear exit face upwards.

English

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.

1. Open the front feeder (1) by lifting the latch (2) and pulling
the cover out and downwards.

1

2

3

2. Remove any paper visible in this area.

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.

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.

5. Push the tray in gently. A full tray is heavy and can damage
the printer if slammed shut.

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.

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.

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).

1. Press the OPEN button and lift the top cover to its fully
upright position.

2. Lift out each of the four image drum cartridges (1) complete
with their respective toner cartridges still in place.

1

28

OKIPAGE 8c Plus

Put the drum cartridges where they will not be scratched
and not exposed to strong light.

3. Inspect the paper path for sheets of paper. Carefully remove
any sheets (2) you find.

2

Clearing a Paper Exit Jam

An indicated paper exit jam means paper has jammed in the
fuser or between the fuser and the point of exit from the printer.

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.

English

Paper jammed under the first image drum should be pulled
forwards through the paper path if possible, not backwards,

2. Push the two coloured fuser latch levers (1) away from you
(towards the rear of the printer).

to avoid spillage of unfused toner into the paper input
area.

2

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.

5. Lower the fuser back into the printer, press down firmly to

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.

7. Look into the rear of the printer and check for any sheets
(4) of paper. Remove any that you find.

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.

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.

Genuine OKI toner is made from non-toxic materials and is
perfectly safe to use, provided you follow a few basic safety
rules.

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.

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.

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.

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.

When to Change a Toner Cartridge

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.

English

User’s Guide 31

Replacing a Toner Cartridge

1. Press the OPEN button and raise the top cover to its fully
upright position.

2. Identify by the coloured label (1) which toner cartridge you
intend to remove.

3. Unlock the cartridge by pulling the coloured lever (2) at
the right-hand end towards you.

1

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.

5. Gently shake the new cartridge from side to side to evenly
distribute the toner along its length.

6. Peel off the white adhesive tape seal from the underside of
the toner cartridge.

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.

4

3

32

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

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.

3

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.

1. Gently wipe clean each of the four LED arrays under the
printer top cover.

2. Close the top cover and press down firmly at both side to
latch it down.

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.

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.

The green surfaces of the drums are light sensitive and should
not be exposed to strong ambient light, and especially not direct
sunlight.

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.

English

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.

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.

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.

34

1. Switch off the printer main power.

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.

4. Grip the top of the drum assembly and lift it straight up and
out of the printer.

OKIPAGE 8c Plus

5. Unpack the new drum cartridge and pull out the protective
sheet of paper.

Pull the sheet straight downwards to avoid tearing.

6. Hold the new cartridge above its intended position and lower
it gently all the way in.

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.

1. Hold down the MENU 1 / Menu 2 key for about 2 seconds

until the menu item COLOR REG ADJUST appears in the
display.

2. Press and release the MENU 1 / Menu 2 key to cycle

through the available items. When the display shows
ENGINE CNT RESET, press ENTER.

English

Locating slots (1) at each side of the printer help you to
correctly position the drum cartridge.

1

7. Remove any plastic foam seal from the top of the new drum
cartridge.

8. Install a new toner cartridge of the appropriate colour,
following the instructions given in the previous section.

User’s Guide 35

1

3. Press and release the MENU 1 / Menu 2 key to cycle

through the available items. When the display shows
CCCCC DRMCNT (“CCCCC” means the colour of the
replaced drum), press the ENTER key to reset the drum
count.

4. If you have changed two or more drums at the same time,
also reset their counts.

5. Press the ON LINE key to exit from the User Menu and
return to the ON LINE (ready) condition.

Replacing Waste Toner Box

The waste toner box should be replaced after approximately
25,000 pages. When the waste toner box needs replacing a
message to that effect will appear on the operator panel display.

1. Lift the catch and open the left-hand side panel.

1

2. Press down against spring pressure on the top of the waste
toner box (1), pull it outwards and lift it clear of the printer.

3. Position the new waste toner box with its drive coupling
(2) towards the front of the printer and the lifting tab (3) at
the top.
