Basic Fax Troubleshooting
For more detailed information of machine Fax settings refer to “Setting
the Fax Facility” in the CX2032 MFP user’s guide pages 58 to 65.
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 dialing method (pulse or tone) for the region. If alternating tones are heard
instead of dialing pulses and the region uses pulse dialing, change the call parameters
( See pages 58 in the CX2032 MFP user’s guide ).
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 dialed.
> If a prefix number must be dialed 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 dialing 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 59 in the CX2032 MFP user’s guide ).
> Finally, 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 ( See “Advanced operation” on page 88
in the CX2032 MFP user’s guide ). 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.
Image of received fax is very poor
Try making a copy of a document on the local machine to make sure it is working properly. If
there is still a problem, contact the person sending the fax and ask them to change their fax
quality and density settings. Ask the person to make a copy of the document on their machine
to ensure that it is working properly. Then ask them to send the fax again.
Dialing was tried with a Speed Dial number but nothing happened
Make sure that the Speed Dial number being used is programmed correctly.
