If a problem occurs, read through the list of problems and solutions before calling for
service.
The MFP will not dial a telephone number.
Check the power cable and wall outlet. Make sure that the telephone line (not external
telephone or handset) is connected to the LINE socket on the back of the machine. If
an external telephone is installed, lift the handset and check for a dial tone. If there
is no dial tone, there may be a problem with the telephone line. If there is a dial tone,
the MFP may be using the wrong dialling method (pulse or tone) for the region. If
alternating tones are heard instead of dialling pulses and the region uses pulse
dialling, change the call parameters.
The display shows a communications error. This indicates any of a number of
problems:
• The MFP may be incompatible with the remote machine, or the remote machine
may not be able to perform the function requested of it such as polling or
confidential faxing.
• 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 that the correct telephone number is being
dialled.
• If a prefix number must be dialled to get an outside line, or if the call is to an
international destination, a pause may need to be entered after the dial prefix or
international dialling code to tell the machine to wait for a dial tone. If there are
frequent problems communicating with a particular remote machine, try
programming the telephone number into a speed dial key, and then change the
parameters for that key.
• Lastly, either the local or remote machine may require servicing. Try sending a fax
to another location to check the local MFP.
Faxing is possible but the image of the document printed by the
remote machine is very poor.
If the faxed document has small type, complex illustrations, photos, or is very light
or very dark, try changing the fax quality and density settings. Copy the document
on the machine to determine how it will transmit. The problem may be caused by
telephone line interference. Try sending the document again later.
Fax sent but received message was completely blank.
Make sure that the document is loaded correctly before faxing; with text face UP in
the ADF or face DOWN on the glass.
