Poor fax send quality. Try changing your resolution to Fine or S.Fine. Make a copy to check your
machine's scanner operation. If the copy quality is not good, clean the scanner.
(See Cleaning the scanner glass on page 161.)
Vertical black lines when sending. Black vertical lines on faxes you send are typically caused by dirt or correction fluid
on the glass strip. Clean the glass strip. (See Cleaning the scanner glass
on page 161.)
Handling Incoming Calls
Difficulty Suggestions
The machine ‘Hears’ a voice as a
CNG Tone.
If Fax Detect is set to on, your machine is more sensitive to sounds. It may
mistakenly interpret certain voices or music on the line as a fax machine calling and
respond with fax receiving tones. Deactivate the machine by pressing
Stop/Exit .
Try avoiding this problem by turning Fax Detect to off. (See
Fax Detect on page 52.)
Sending a fax call to the machine. If you answered on an external or extension telephone, press your Remote
Activation Code (the factory setting is
l 5 1 ). When your machine answers, hang up.
Custom features on a single line. If you have Call Waiting, Call Waiting/Caller ID, an alarm system or other custom
feature on a single telephone line with your machine, it may create a problem
sending or receiving faxes.
For example: If you subscribe to Call Waiting or some other custom service and
its signal comes through the line while your machine is sending or receiving a fax,
the signal can temporarily interrupt or disrupt the faxes. Brother's ECM (Error
Correction Mode) 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 telephone line with no
custom features is recommended.

Vertical black lines or streaks on copies are typically caused by dirt or correction
