Handling incoming calls

Difficulties
The machine 'Hears' a voice as a
CNG Tone.
Sending a Fax Call to the machine. If you answered on an external or extension telephone, press your Fax Receive
Custom features on a single line.
Suggestions
Make sure the machine is in the correct receive mode for your setup. (See
Receiving a fax on page 44.) 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.
Suggestions
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 150.)
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 67), print fax messages in memory (see Printing a fax from the
memory on page 49) or cancel a delayed fax or polling job (see Checking and
cancelling waiting jobs on page 43). 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 130.)
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 150.)
Suggestions
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 47.)
Code [default setting is (l 51)]. When your machine answers, hang up.
If you have Call Waiting, Call Waiting/Caller ID, Caller ID, Voice Mail, an
answering machine, an alarm system or other custom feature on a single
telephone line with your machine, it may create a problem sending or receiving
faxes.
For Example: If you subscribe to Call Waiting or some other custom service and
its signal comes through the line while your machine is sending or receiving a fax,
the signal can temporarily interrupt or disrupt the faxes. Brother's ECM feature
should help overcome this problem. This condition is related to the telephone
system industry and is common to all devices that send and receive information
on a single, shared line with custom features. If avoiding a slight interruption is
crucial to your business, a separate line with no custom features is recommended.
