Suggestions
If you have Call Waiting, RingMaster, Voice Mail, an
answering machine, alarm system or other custom
features on a single phone line with your fax machine, it
may create a problem sending or receiving fax data.
For Example: Your Brother machine handles the Caller
ID and Call Waiting/Caller ID subscriber services.
However, if you subscribe to only 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 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.
Using Call Waiting/Caller ID: If you are having a
telephone conversation and a fax communication signal
comes through on Call Waiting Caller ID, 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.
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 22-16 and 22-17.)
Make sure the Brother TWAIN Driver is selected as the
primary source. In PaperPort
highlight the Brother TWAIN Driver and click Select.
Check the following:
• The machine is plugged in. (See Page 2-9.)
• The toner cartridge and drum unit are installed
properly. (See Page 2-3.)
• The interface cable is securely connected between the
machine and computer. (See Quick Setup Guide.)
• Check to see if the LCD is showing an error message.
(See Page 22-1.)
Reset the machine or unplug the electrical cord and plug
it back in. Check the primary settings in your application
software to make sure it is set up to work with your
machine.
