If you are having problems sending or
receiving a fax due to possible interference on
the telephone line or if you are using a VoIP
system, we recommend changing the modem
speed to minimise errors in fax operations.

Press a or b to select the following:
a. Select [Initial Setup].
Press OK.
b. Select [Compatibility].
Press OK.
c. Select [Normal] or [Basic(for
VoIP)]. Press OK.
• [Basic(for VoIP)] reduces
the modem speed to 9,600 bps
and turns off colour fax receiving
and Error Correction Mode
(ECM), except for colour fax-
sending. Unless interference is a
recurring problem on your
telephone line, you may prefer to
use it only when needed.
To improve compatibility with
most VoIP services, Brother
recommends changing the
compatibility setting to
[Basic(for VoIP)].
• [Normal] sets the modem
speed at 14,400 bps.

Press Stop/Exit.
• VoIP (Voice over IP) is a type of phone
system that uses an Internet
connection, rather than a traditional
phone line.
• 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.
