The machine 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 machine may be using
the wrong dialling method (pulse or tone) for the region.

The display shows a communications error:
This alarm indicates any of a number of problems. The machine
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 One-Touch key, and then change the One-Touch
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 machine.

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.
