Printing or printing received faxes
Difficulties Suggestions
 Condensed print
 Horizontal streaks
 Top and bottom sentences are
cut off
 Missing lines
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.
Poor print quality See Improving the print quality on page 131.
Vertical black lines when receiving The corona wires for printing may be dirty. Clean the corona wires on the drum
unit. (See Cleaning the corona wires on page 74.)
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 1-877-BROTHER

Received faxes appear as split or

blank page, your paper size setting may not be correct for the paper you are using.
