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 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 dama ged; 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. Allow enough
room around the printer for adequate ventilation.

• The printhead can get quite hot when it has been printing for
a length of time. Do not touch the printhead until it has had a
chance to cool off.

• 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 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 (10 for Sweden only) amperes.

• The power outlet into which you plug your printer must
remain accessible at all times. (CE)

• Do not poke anything into the ventilation slots on the printer;
you could get a shock or cause a fire.

English

iHelp Guide

• 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.

• 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.

Troubleshooting

Problem: Nothing happens when I turn on the printer.
Solution: Check the power cable connection and power

outlet to your printer. If you are using a power
strip, make sure it is turned on, and that the
fuse has not blown nor the circuit breaker
tripped.

Problem: The printer does not print when data is sent.
Solutions: (1) Is the SEL light on? If not, press the

SEL key.

(2) Check that the interface cable is securely

connected to both the printer and the
computer.

(3) If you have the optional serial interface

board installed, check to be sure that it is
firmly seated in the printer.

Problem: I'm getting strange symbols, incorrect fonts,

etc., when I try to print a document.

Solution: (1) Check to be sure that the printer driver you

have selected in your software matches the
printer emulation. (Press SHIFT and SEL
keys, then press GROUP key: this will print
a line showing the emulation you have
selected.)

(2) If you have embedded any printer

commands in your software, check to be
sure that you entered them correctly.

Problem: I've installed a new ribbon and the printing is

smeared and streaked.

Solution: The ribbon shield is either loose or missing.

Remove the ribbon cartridge and check the
clear plastic ribbon shield: if it's loose, secure
it in place, if it is missing, find it and reinstall
it.

8 ML3310/1 1

Problem: The ALARM light is on and the Character Pitch

15 light is flashing.

Problem: My word processor files don’t print the way I

have the menu and front panel set.

Solution: This indicates a paper jam. Press the SEL key

and correct the paper jam situation ( see
“Clearing Paper Jams” earlier in this manual).

Problem: The ALARM light is on and the Character Pitch

10 light is flashing.

Solution: This indicates that the paper lever is set at the

wrong position for the paper you are trying to
use: move it to the proper setting.

Problem: The ALARM light is blinking.
Solution: Try turning the printer off and then back on

again. If the light still blinks, call for service.

Problem: The printer needs paper, but the ALARM light

is not on and I can’t load the paper.

Solution: Press and release the SEL key, then hold the

SHIFT key and press the RESET
(CHARACTER PITCH) key: this resets the
printer.

Solution: Before sending a file to the printer, many word

processors send either an “initialisation string”
or an I-Prime signal to the printer. The
initialisation string contains codes that override
the panel and menu settings.

To change your printer to ignore the reset code,
enter the Menu Mode, go down to the Set-Up
group and change the setting for Reset Inhibit
to Yes (see Menu Mode later in this manual).

The I-Prime signal will automatically override
any front panel settings you have made. To
eliminate this problem, enter the Menu Mode,
go down to the Parallel Interface group and
change the setting for I-Prime to Invalid (see
Menu Mode later in this manual).

English

9Help Guide

Problem: The Print Quality and Character Pitch keys on

the front panel won’t work.

Solution: The Operator Panel Function in the printer

menu can be used to disable these buttons. If
the printer is part of a customised system or if
it is used by a number of people, the system
manager may have used this option to make
sure the printer is always set properly.

Problem: Continuous-form paper is sticking to the paper

separator.

Solution: In cold dry weather, static charges can build

up and make the paper cling to the paper
separator. Try moving the paper guides together
so that the paper rests on the guides rather than
on the separator.

Problem: Ink smears on paper.
Solution: This may be caused by excessive printhead

travel from the centring position when printing
narrow columns. Set Centring Position to
MODE 1. On ML3311 also try MODE 2. (See
Menu Mode).
