F AX PROBLEM CHECKLIST
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 (See “Initial set up” on page 66).
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.
> 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 (use the Pause key) 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 (See “Advanced set up” on
page 67).
> 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
