Telephone Line Interference/VoIP
Related Models: MFC-J1010DW
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.
1. Press Settings.
2. Press a or b to make your selections:
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.
3. Press Stop/Exit.
• VoIP (Voice over IP) is a type of phone system that uses an Internet connection, rather than a traditional
phone line.
