Problems sending and receiving faxes due to
possible interference on the telephone line
may be solved by reducing the modem speed
to minimise errors in fax transmission. If you
are using a Voice over IP (VoIP) service,
Brother recommends changing the
compatibility to Basic (for VoIP).
• VoIP is a type of phone system that
uses an Internet connection, rather
than a traditional phone line.
• Telephone providers frequently bundle
VoIP together with Internet and cable
services.
• Brother does not recommend the use
of a VoIP line. VoIP limitations in
general can cause some functions of
the fax machine not to work correctly.

Some receive modes answer automatically
(Fax Only Mode and Fax/Tel Mode). You may
want to change the Ring Delay before using
these modes.
Fax Only Mode
([Fax] or [Fax Only] in the machine's
menu)
Fax Only Mode automatically answers
every call as a fax.
Fax/Tel Mode
([Fax/Tel] in the machine's menu)
Fax/Tel Mode helps you manage incoming
calls, by recognising whether they are fax
or voice calls and handling them in the
following ways:
• Faxes will be received automatically.
• Voice calls will start the F/T ring to tell
you to pick up the call. The F/T ring is a
fast pseudo/double-ring made by your
machine. See Related Information:
