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.

Most computer software will send a form feed character
at the end of the print job so that the last page is ejected.
If it does not, the printer can automatically eject the last
page after a period of inactivity.

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.

This setting determines whether the printer will remain
on-line (ON) or go off-line (OFF) when one of the toner
cartridges has only enough toner left for about 100 pages.

Many messages which may appear from time to time
can be cleared by pressing the Recover key if this
function is ON. If it is set to JOB, the host computer may
be able to clear such warnings by downloaded
commands. This setting is not relevant when using
PostScript emulation.

In PostScript mode this setting determines whether an
