Suggestions
Usually this is caused by a poor telephone connection. If your copy looks good,
you probably had a bad connection, with static or interference on the telephone
line. Ask the other party to send the fax again.
See Improving the print quality on page 119.
One of the corona wires for printing may be dirty. Clean the four corona wires.
(See Cleaning the corona wires on page 155.)
The sender's scanner may be dirty. Ask the sender to make a copy to see if the
problem is with the sending machine. Try receiving from another fax machine.
If the problem continues, call Brother or your dealer for service.
If the received faxes are divided and printed on two pages or if you get an extra
blank page, your paper size setting may not be correct for the paper you are using.
(See Paper size on page 23.)
Turn on auto reduction. (See Printing a reduced incoming fax on page 48.)
Suggestions
Check for a dial tone.
Change Tone/Pulse setting. (See the Quick Setup Guide.)
Check all line cord connections.
Check that the machine is plugged in and switched on.
If an external telephone is connected to the machine, send a manual fax by lifting
the handset of the external telephone and dialling the number. Wait to hear fax
receiving tones before pressing Mono Start or Colour Start.
