machine may be using the wrong dialing method
(pulse or tone) for your area. If you hear changing
tones instead of dialing pulses and you know that
your area uses pulse dialing, 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 instituted the correct programming to
work with a PBX (see Connecting to a PBX in Instal-
lation).
o 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 experi-
encing a paper jam. Bad telephone line conditions
can also 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 an
access digit to get an outside line, or if you are dial-
ing internationally, you may need to enter a pause
(using the Pause One-Touch key) after the access
digit 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 (see “Dial
Directories” on page 29). Lastly, either your fax
machine or the remote fax machine may need servic-
ing. Try sending a fax to another location to check
your machine.
o 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 Reso-
lution and Type of Original settings (see “Loading
Documents” on page 34 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.
o You keep getting reports you do not want. Check
your user function settings and turn off the reports
you do not want. See “Customizing Features &
Operations” on page 53.
