Your fax machine will not dial. Check the power cable and
wall outlet. Make sure that your telephone line (not your external
telephone or handset) is connected to the LINE outlet on the
back of your fax machine. If you have an external telephone
connected, lift the handset and check for a dial tone. If you do
not have an external telephone connected, press the HOOK/V.
REQUEST key and check for a dial tone. If you do not hear
one, there may be a problem with your telephone line. If you do
hear a dial tone, your fax machine may be using the wrong
dialling method (pulse or tone) for your area. If you hear
changing tones instead of dialling pulses and you know that your
area uses pulse dialling, refer to the MF(TONE)/DP(PULSE)
dial parameter setting in Programming. If your fax machine is
connected to a PBX, make sure you have programmed to work
with a PBX (see Connecting to a PBX in Installation).
The display shows a communication error. This alarm
indicates any of a number of problems. You may be trying to
communicate with an incompatible fax machine (your 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 also be out of paper or experiencing a paper jam.
Bad telephone line conditions can also cause communication
errors. Try sending the fax again and check to make sure you are
dialling the correct telephone number. If you have to dial a prefix
number to get an outside line, or if you are dialling
internationally, you may need to enter a pause (using the PAUSE
One Touch key) after the dial prefix or international dialling
86
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 (see Dial Directories). 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 Transmit Resolution and Type of Original settings (see
Loading Documents in Basic Operations). Copy the document
on your fax machine to see how it will transmit. The problem
may be caused by telephone line interference. Try sending the
document again later.
You keep getting reports you do not want. Check your user
function settings and turn off the reports you do not want. See
Programming.
You sent a fax but it was received completely blank. Make
sure that you have correctly loaded your document face down.
The image received on your fax 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.
