Troubleshooting and Routine Maintenance
Sending Faxes
Cannot send a fax. Check all line cord connections.
Make sure that the Fax key is illuminated. (See Entering Fax mode on
page 38.)
Ask the other party to check that the receiving machine has paper.

says 'Result:NG'. If you send a PC FAX message and get 'Result:NG' on the Transmission
Verification Report, your machine may be out of memory. To gain extra memory,
you can turn off Advanced Fax Operation (see Turning off Advanced Fax
Operations on page 8! ), print fax messages in memory (see Printing a fax from
the memory on page 51 ) or cancel a Delayed Fax or Polling Job (see Canceling a
fax in progress on page 39). If the problem continues, ask the telephone company
to check your phone line.
If you often get transmission errors due to possible interference on the phone line,
try changing the menu setting of Compatibility to Basic. (See Phone line
interference on page 143.)
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.

the scanner on page 146.)

Custom features on a single line. If you have Call Waiting, Calt WaitingtCaller ID, Voice Mail, an alarm system or
other custom feature on a single phone Iine 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 phone line with no custom features is
recommended.
