TROUBLESHOOTING AND ROUTINE MAINTENANCE
22 - 12
If you are having difficulty with your MFC
If you think there is a problem with the way your faxes look,
make a
copy first
. If the copy looks good, the problem is probably not your
MFC. Check the chart below and follow the troubleshooting tips.
DIFFICULTY
SUGGESTIONS
Printing or Receiving Faxes
Condensed print and
horizontal streaks or the top
and bottom of sentences are
cut off.
If your copy looks good, you probably had a bad connection, with static or
interference on the telephone line. If the copy looks bad, clean the scanner
area. If there is still problem, call Brother or your dealer for service.
Poor quality print.
Vertical black lines when
receiving.
Sometimes you may see vertical streaks/black lines on the faxes you
receive. Your MFC’s primary corona wire for printing may be dirty, or the
sending party’s fax scanner may be dirty. Clean your primary corona
wire (See
on page 22-26), or 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 your
dealer for service.
Horizontal streaks; lines are
missing.
You may get a fax with horizontal streaks or with missing lines. Usually
this is caused by a poor telephone connection. Ask the other party to
send the fax again.
Received faxes appear as split
or blank pages.
If the received data is divided and printed on two pages or if you get an
additional blank page, your Paper Size setting may not be correct for the
paper you are using (See
on page 2-1). Make
sure that auto reduction function setting is turned on. (See
reduced incoming fax (Auto Reduction)
Phone Line or Connections
Dialling does not work
Check for a dial tone. Change
Tone/Pulse
setting. (See
or Pulse dialling mode (Except for the Nordic Countries)
Check all line cord connections. Check power cord connection. Send a
manual fax by lifting the external handset and dialling the number. Wait
to hear fax receiving tones before pressing
Start
.
The MFC does not answer
when called.
Make sure the MFC is in the correct receiving mode for your setup. (See
on page 6-7.) Check for a dial tone. If
possible, call your MFC to hear it answer. If there is still no answer,
check the telephone line cord connection. If there is no ringing when you
call your MFC, ask your telephone company to check the line.
