The display shows a communication error.
• A
COMMUN. ERROR message indicates any of a number
of problems.
• You may be trying to communicate with an incompatible
fax machine (your fax machine can only communicate
with ITU-T Group 3 fax machines).
• The remote machine may not be able to perform the
function that you want, such as polling or confidential
messages.
• The remote machine may be out of paper or experiencing
a paper jam.
• Bad telephone line conditions can cause communication
errors. Try sending the fax again and check to make sure
you are dialing the correct telephone number.
• If you have to dial a prefix number to get an outside line,
or if you are dialing internationally, you may need to enter
a pause (using the Pause One Touch key) after the dial
prefix or international dialing code to tell your machine to
wait for a dial tone.
• If you have frequent problems communicating with a
particular remote fax machine, try programming the
number into one of your One Touch keys and then
changing the One Touch Parameters for that One Touch
key. Refer to the “Programming Your Speed Dial Directory,
One Touch Faxing” section of this handbook.
• Lastly, either your fax machine or the remote fax machine
may need servicing. Try sending a fax to another location
to check your machine.
You sent a fax but the image the remote fax machine
received was very poor.
• If your document had a lot of small type, complex
illustrations, photos, or was very light or very dark, try
changing your resolution and contrast settings. Refer to
the “Basic Faxing Operations, Preparing Documents for
Faxing, Loading Documents” section of this handbook.
• Copy the document on your fax machine to preview how
it will transmit. The problem may be caused by telephone
line interference.
• Try sending the document again later.
You sent a fax but it was received completely blank.
• Make sure that you have loaded your document face
down.
