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 text on
your printed pages. You can clean Black only,
three colours at a time
(Yellow/Cyan/Magenta), or all four colours 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.

Note
If you clean the print head at least five
times and the print has not improved, try
installing a new Brother Original
Innobella™ ink cartridge for each problem
colour. Try cleaning the print head again
up to five more times. If the print has not
improved call your Brother dealer.
Checking the print quality
A
If faded or streaked colours and text appear
on your printouts, some of the print head
nozzles may be clogged. You can check this
by printing the Print Quality Check Sheet and
looking at the nozzle check pattern.
