OKI 4580 Manuel D’Utilisation

The image received on your machine was very
poor. Contact the person sending you the fax and
ask them to change their Transmit Resolution and
Type of Original settings. Ask the person to make a
copy of the document on their fax machine to
ensure that it is working properly. Then ask them to
send the fax again. If you still have a problem, try
making a copy of a document on your machine to
make sure it is working properly.

You tried dialing with a One-Touch key or an
Auto Dial code but nothing happened. Make
sure that something is programmed into the One-
Touch key or Auto Dial code you are using. Check
the fax number to make sure it was entered cor-
rectly (see the Dial Directories chapter). When you
are dialing with an Auto Dial code, be sure to press
the AUTO DIAL key before you enter the code. If
your machine has the Auto Start feature turned off,
you will have to press the START key before dialing
will begin (see the section on Programming).

Your machine does not answer the phone or
receive faxes. First check to see that the power
cord is connected to the AC outlet. Also check the
reception mode you are using. Your machine will
not automatically receive faxes in manual answer-
ing mode [TEL]. See “Setting the Answering Mode”
in the Installation section.

Your received documents are light or have
vertical streaks on them and you are not out of
toner. Gently wipe the lens surface of your
machine’s LED array and then see if the machine
works properly (refer to “Replacing the Toner
Cartridge”). If your machine still does not work
properly, remove the image drum unit (refer to
“Replacing the Image Drum Unit”), tap the toner
cartridge, and slowly swing it 20-30 degrees
vertically several times. Be careful not to let the
toner leak from the cartridge. If this does not work,
you may need to replace your image drum unit.
Contact your dealer to get a replacement.

You set your machine for delayed transmission
but it did not send. Check the display to make
sure that you have set your machine’s clock to the
correct time. See “Setting the Clock” in the Installa-
tion section.

Your machine disconnected before you could
answer a voice request. You must answer a voice
request while the warbling tone is sounding. When
you hear the warbling tone, press the HOOK/V.
REQUEST key after picking up your handset.

Your machine will not poll a remote fax ma-
chine. Call the person at the remote fax machine
and make sure that they have loaded documents
and set their fax machine in polling transmission
mode.

Your machine is connected to a PBX and you
can not dial out. You must enter your dial prefix
before the telephone number for each number that
you dial or program into your machine. Also, your
machine must be programmed for PBX operation
before it will work. See “Connecting to a PBX” in
the Installation section.

You want to answer an external telephone but
your machine always answers first. If you are
using an external telephone, change your
machine’s ring response user function setting. See
the Programming section.

Your received faxes sometimes look distorted.
If the document received is longer than the paper
you have loaded into your paper tray, your machine
automatically reduces the length of the document
to fit on your paper.

If the document received is wider than the paper
you have loaded into your paper tray, your machine
can be programmed to reduce the width of the
document to fit on your paper. This feature is called
Width Reduction. Using it will affect the appearance
of the received fax.

This type of problem could also be communication
related.

You are constantly receiving unsolicited adver-
tising on your machine. Try using the closed
network function. See “Receiving Faxes” in the
Basic Operations section.

Your machine does not immediately switch to
TEL mode when you make or receive a voice
call. Try pressing the Stop key. Your machine will
return to standby mode so that you can converse.
This condition may happen infrequently due to
telephone line conditions, or the type of external
telephone used. If this problem happens often,
consult your service representative.
