Telephone line or connections
Difficulties
Suggestions
Dialing does not work.
Check for a dial tone.

Check all line cord connections.
Check that the machine is plugged in and switched on.
Send a manual fax by pressing
Hook
or by lifting the handset of an external
telephone and dialing the number. Wait to hear fax receiving tones before
pressing
Black Start
or
Color Start
.
The machine does not answer
when called.
Make sure the machine is in the correct receive mode for your setup. (See
Receiving a fax
on page 41.) Check for a dial tone. If possible, call your machine
to hear it answer. If there is still no answer, check the telephone line cord
connection. If you do not hear ringing when you call your machine, ask your
telephone company to check the line.
Sending faxes
Difficulties
Suggestions
Poor sending 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
on page 149.)
Transmission Verification Report
says ‘RESULT:NG’.
There is probably temporary noise or static on the line. Try sending the fax again.
If you are sending a PC Fax message and get ‘RESULT:NG’ on the Transmission
Verification Report, your machine may be out of memory. To free up extra
memory, you can turn off fax storage (see
Turning off remote fax
options
on page 65), print fax messages in memory (see
Printing a fax from the
memory
on page 46) or cancel a delayed fax or polling job (see
Checking and
canceling waiting jobs
on page 40). 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 Compatibility setting to
Basic(for VoIP)
. (See
Telephone line interference
on page 128.)
Vertical black lines when sending.
Black vertical lines on faxes you send are typically caused by dirt or correction fluid
on the glass strip. (See
Cleaning the scanner
on page 149.)
Handling incoming calls
Difficulties
Suggestions
The machine ‘Hears’ a voice as a
CNG Tone.
If Easy Receive 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 Easy Receive to off. (See
Easy
receive
on page 44.)
Sending a Fax Call to the machine. If you answered on an external or extension telephone, press your Fax Receive
Code [default setting is (
l
51)]. When your machine answers, hang up.
