Handling incoming calls
Difficulties 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 43.)
Sending a Fax Call to the machine. If you answered on an external or extension telephone, press your Remote
Activation Code (default setting is l51). When your machine answers, hang up.
Custom features on a single line. If you have Call Waiting, Call Waiting/Caller ID, Caller ID, Voice Mail, an
answering machine, 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 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.
Menu access difficulties
Difficulties Suggestions
The machine beeps when you try to
access the Setup Receive and
Setup Send menus.
If Fax is not illuminated, press it to turn on Fax mode. The Setup Receive
setting (Menu, 2, 1) and Setup Send setting (Menu, 2, 2) are available only when
the machine is in Fax mode.
Copy difficulties
Difficulties Suggestions
Cannot make a copy
Make sure that Copy is illuminated. (See Entering copy mode
on page 68.)
Vertical black line appears in
copies.
Black vertical lines on copies are typically caused by dirt or correction fluid on the
glass strip, or the corona wire for printing is dirty. (See Cleaning the scanner
on page 130 and Cleaning the corona wire on page 132.)
The machine does not scan all the
pages of your document.
Make sure that the ADF output tray does not contain more than 20 sheets.
