Cleaning the print head B
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 and ink cartridges if you
get a horizontal line in the text or graphics or
blank text on your printed pages. You can
clean Black only, three colors at a time
(Cyan/Yellow/Magenta), 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.

c Press Black, Color or All.

Note

installing a new Genuine Brother
Innobella™ replacement 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.)
