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
correctly (see Dial Directories). When you are dialling with an

AUTO DIAL

 code, be sure to press the 

AUTO DIAL

 key before

you enter the code. If your fax machine has the Auto Start feature
turned off, you will have to press the 

START

 key before dialling

will begin (see Programming).

Your fax machine does not answer the phone or receive faxes.
First check to see that the power cable is connected to the power
outlet and the telephone line is connected to 

LINE

. Also check

the reception mode you are using. Your fax machine will not
automatically receive faxes in manual answering mode [TEL].
See Setting the Answering Mode in Installation.

Your received documents are light or have vertical streaks
on them and you are not out of toner. Gently wipe the lens
surface of the LED array on your fax machine and then see if
the machine works properly (refer to Replacing the Toner
Cartridge). If your fax 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 fax machine for delayed transmission but it did
not send. Check the display to make sure that you have set the

clock on your fax machine to the correct time. See Setting the
Clock in Installation.

Your fax machine disconnected before you could answer a
voice request. You must answer a voice request while the
warbling tone is being emitted. When you hear the warbling
tone, press the 

HOOK/V. REQUEST

 key after picking up your

handset.

Your fax machine will not poll a remote fax machine. 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. Check also if their fax machine uses either
standard polling transmission or ITU polling transmission.

Your fax machine is connected to a PBX and you cannot 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 fax machine must be programmed for PBX operation
before it will work. See Connecting to a PBX in Installation.

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

Your received faxes sometimes look distorted. If the document
received is wider or longer than the paper you have loaded into
your paper tray, your fax machine automatically reduces either
the width or the length of the document to fit on your paper.
This type of problem could also be communication related.
