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.

SUGGESTIONS
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 11-16.
Sometimes you may see vertical streaks/black lines on the faxes you receive.
Your MFC's primary corona wire may be dirty, or the sending party's fax scanner
may be dirty. Clean your primary corona wire (See Cleaning the corona wire on
page 11-24), 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 Brother Customer Service at 1-800-284-4329 (in USA) or
1-877-BROTHER (in Canada).
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.
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 Setting the Paper Size on page 2-4.) Make sure that auto reduction
menu setting is turned on. (See Printing a reduced incoming fax (Auto Reduction)
on page 4-4.)
Check for a dial tone. Change Tone/Pulse setting. (See Tone or Pulse (For
Canada only) on page 5-4.) Check all line cord connections. Check power cord
connection. Send a manual fax by pressing Hook or by lifting the handset of the
external phone and dialing the number. Wait to hear fax receiving tones before
pressing Start.
Make sure the MFC is in the correct receiving mode for your setup. (See Basic
sending operations on page 3-5.) 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.
