Receiving Faxes
Difficulty Suggestions
Cannot receive a fax Check the line cord connection.
Make sure the machine is in the correct receiving mode for your setup. (See
Receive modes on page 35.)

of Compatibility to Basic(for VoIP). (See Telephone line interference
on page 109.)
Sending Faxes
Difficulty Suggestions
Cannot send a fax Check the line cord connection.
Make sure that the Fax key is illuminated. (See Entering Fax mode
on page 28.)
Ask the other party to check that the receiving machine has paper.
Print the Transmission Verification Report and check for an error. (See Reports
on page 60.)
Transmission Verification Report
says ‘Result:NG’ or
‘Result:ERROR’.
There is probably temporary noise or static on the line. Try sending the fax again.
If you send a PC FAX message and get
‘Result:ERROR’ on the Transmission
Verification Report, your machine may be out of memory. To gain extra memory,
you can turn off Fax Storage (see Turning off Remote Fax Options on page 54),
print fax messages in memory (see Printing a fax from the memory on page 39) or
cancel a Delayed Fax or Polling Job (see Checking and cancelling waiting jobs
on page 33). If the problem continues, ask the telephone company to check your
telephone line.
If you often get transmission errors due to possible interference on the telephone
line, try changing the menu setting of Compatibility to Basic(for VoIP). (See
Telephone line interference on page 109.)
Poor fax send quality. Try changing your resolution to Fine or S.Fine. Make a copy to check your
machine's scanner operation. If the copy quality is not good, clean the scanner.
(See Cleaning the scanner glass on page 122.)
Vertical black lines when sending. If the copy you made shows the same problem, clean the scanner. (See Cleaning
the scanner glass on page 122.)
Handling Incoming Calls
Difficulty Suggestions
The machine ‘Hears’ a voice as a
CNG Tone.
If Fax Detect is set to On, your machine is more sensitive to sounds. It may
mistakenly interpret certain voices or music on the line as a fax machine calling
and respond with fax receiving tones. Deactivate the machine by pressing
Stop/Exit. Try avoiding this problem by turning Fax Detect to Off. (See Fax Detect
on page 38.)
Sending a fax call to the machine. If you answered at the machine, press Mono Start and hang up at once. If you
answered on an extension telephone, press your Remote Activation Code (default
setting is l51). If you answer on an external telephone (connected to the EXT
jack), press Start to receive the fax. When your machine answers, hang up.
