Custom features on a single line. If you have Call Waiting, Call Waiting/Caller ID, Caller ID, RingMaster, 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 the Fax key 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 quality difficulties
Difficulties Suggestions
Vertical black line appears in
copies.
Black vertical lines on copies are typically caused by dirt or correction fluid on the
glass strip, or one of the corona wires for printing is dirty. (See Cleaning the
scanner glass on page 119 and Cleaning the corona wire on page 122.)
