Printing or receiving 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 113.

Vertical black lines when receiving

One of the corona wires for printing may be dirty. Clean the four corona wires. 
(See 

Cleaning the corona wires

 on page 147.)

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 (

in 

USA

) or 1-877-BROTHER (

in Canada

).

Received faxes appear as split or 
blank pages.

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 21.

Turn on auto reduction. (See 

Printing a reduced incoming fax

 on page 43.)
