If You Are Having Difficulty with Your FAX/
MFC
If you think there is a problem with your FAX/MFC, make a copy first. If the copy
looks good, the problem is probably not your FAX/MFC. Check the chart below
and follow the troubleshooting tips.
Condensed Print and Horizontal Streaks;
Top and Bottom of Sentences Cut Off
If your copy looks good, you probably had a bad connection, with static or
interference on the phone line. If the copy looks bad, call Brother Customer
Service at 1-800-284-4329.
Vertical Black Lines When Receiving
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 Customer Service at 1-800-284-4329.
