Your MFP machine won’t dial. Check the power cord and wall outlet.
Make sure that your telephone line (not your external telephone or hand-
set) is connected to the LINE outlet on the back of your MFP machine. If
you have an external telephone connected, lift the handset 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 MFP 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) user function
setting in the Programming section.
The display shows a communication error. This alarm indicates any of
a number of problems. You may be trying to communicate with an incom-
patible fax machine (the standard unit 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 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 fre-
quent 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 section). Lastly, either your MFP 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 Resolu-
tion and Type of Original settings (see “Loading Documents” in the Basic
Operations section). Copy the document on your MFP machine to see
how it will transmit. The problem may be caused by telephone line inter-
ference. 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
section.
