(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) user function setting in the
Programming chapter.
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 mes-
sages. 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
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 the Dial Directories chapter). 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 docu-
ment 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 set-
tings (see Loading Documents in the Basic
Operations chapter). Copy the document on your
fax machine to see how it will transmit. The prob-
lem 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 the Programming chapter.
You sent a fax but it was received completely
blank. Make sure that you have loaded your docu-
ment 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.
