Suggestions
The machine knows the incoming call is not a
fax so it is signaling you to answer the
telephone call. Pick up the machine's handset
or answer from an extension or external phone
and press your machine's Telephone Answer
Code (default setting is #51).
hang up immediately. If you answered at an
extension or external phone, press your machine's
Remote Activation Code (default setting is
51). When your machine answers, hang up.
The Caller ID signal is sent ten seconds after
the Call Waiting Signal and speaking may
interfere with it. When you hear the Call
Waiting signal, ask the other party to hold
while you catch the other call. Then stop
speaking until you see the Caller ID on the LCD.
If you have Call Waiting, Caller ID, Call
Waiting/Caller ID, Ring Master, Voice Mail, an
answering machine, alarm system or any other
custom features on a single phone line with
your fax machine, it may create a problem
sending or receiving fax data.
Example #1: If you are having a telephone
conversation and a fax communication signal
comes through on your Call Waiting Caller ID
feature, you can verify that the second call is a
fax by switching to it. You have the option to
receive the fax call, by asking the first caller to
hang up to clear the line.
Example #2: If you are sending or receiving a
fax message while a Call Waiting Caller ID (or
other custom feature) signal comes through on
the line, the signal can temporarily interrupt or
disrupt the fax data. 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.
Sometimes you may see vertical streaks on
your copies. Either the scanner or the primary
corona wire for printing is dirty. Clean them
both. (See pages 17-20 and 17-21.)
