Cleaning the print head A
To maintain good print quality, the machine
will automatically clean the print head when
needed. You can start the cleaning process
manually if there is a print quality problem.
Clean the print head if you get a horizontal
line in the text or graphics, or blank spots
where text should appear on your printed
pages. You can clean Black only; Yellow,
Cyan, and Magenta together; or all four
colors at once.
Cleaning the print head consumes ink.
Cleaning too often uses ink unnecessarily.
IMPORTANT
DO NOT touch the print head. Touching
the print head may cause permanent
damage and may void the print head's
warranty.
a Press Menu, 1, 2.
b Press a or b to choose Black, Color or
All.
Press OK.
The machine cleans the print head.
When cleaning is finished, the machine
will go back to FAX mode.
NOTE
• If you clean the print head at least five
times and the print has not improved, try
installing a new Genuine Brother Brand
replacement ink cartridge for each
problem color. Try cleaning the print head
again up to five more times. If the print has
not improved, call Brother Customer
Service. (See Brother numbers
on page i.)
• You can also clean the print head from
your PC.
