Receiving Faxes
Difficulty Suggestions
Cannot receive a fax. Make sure your machine has a dial tone by pressing Hook in Fax mode. If you
hear static or interference on your fax line, call your local telephone provider.
Check all line cord connections. Make sure the telephone line cord is plugged into
the telephone wall jack and the LINE jack inside the machine. If you subscribe to
DSL, VoIP or MagicJack services, call your service provider for connection
instructions. To lower the modem speed and turn off ECM (error correction mode),
see Telephone line interference / VoIP on page 135.
Make sure the machine is in the correct Receive Mode. This is determined by the
external devices and telephone subscriber services you have on the same line as
the Brother machine. (See Choose the correct Receive Mode on page 52.)
If you have a dedicated fax line and want your Brother machine to automatically
answer all incoming faxes, select Fax Only mode.
If your Brother machine shares a line with an external answering machine, select
External TAD mode. In External TAD mode, your Brother machine will
automatically receive incoming faxes and voice callers will be able to leave a
message on your answering machine.
If your Brother machine shares the line with a Voice Mail subscriber service, see
Voice Mail on page 63.
If your Brother machine is on a line with the Distinctive Ring subscriber service,
see Distinctive Ring on page 64.
If your Brother machine shares a line with other telephones and you want it to
automatically answer all incoming faxes, select Fax/Tel mode. In Fax/Tel
mode, your Brother machine will automatically receive faxes and produce a
pseudo/double-ring to alert you to answer voice calls.
If you do not want your Brother machine to automatically answer incoming faxes,
select Manual mode. In Manual mode, you must answer every incoming call and
activate the machine to receive faxes.
Another device or service at your location may be answering the call before your
Brother machine answers. To test this, lower the Ring Delay setting:
 If the Receive Mode is set to Fax Only or Fax/Tel, reduce the Ring Delay
to 1 ring. (See Ring Delay on page 55.)
 If the Receive Mode is set to External TAD, reduce the number of rings
programmed on your answering machine to 2.
 If the Receive Mode is set to Manual, DO NOT adjust the Ring Delay setting.
Have someone send you a test fax:
 If you received the test fax successfully, your machine is operating correctly.
Remember to reset your Ring Delay or answering machine setting back to
your original setting. If receiving problems recur after resetting the Ring Delay,
then a person, device, or subscriber service is answering the fax call before
the machine has a chance to answer.
 If you were not able to receive the fax, then another device or subscriber
service may be interfering with your fax reception or there may be a problem
with your fax line.
