Sending a Fax Call to the machine. If you answered on an external or extension telephone, press your Remote
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 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.
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 glass on page 127.)
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:ERROR' 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 63), print fax messages in memory (see Printing a fax from the memory
on page 45) or cancel a delayed fax or polling job (see Checking and cancelling
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)(For MFC-7450,
MFC-7840N and MFC-7840W, Normal or Basic(for VoIP)). (See Telephone
line interference on page 113.)
Black vertical lines on faxes you send are typically caused by dirt or correction fluid
on the glass strip. (See Cleaning the scanner glass on page 127.)
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 43.)

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.
