Cleaning the print head B
To maintain print quality, the machine will
automatically clean the print head. 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 or blank text in the text or
graphics on your printed pages. You can
clean Black only, three colours at a time
(Cyan/Yellow/Magenta), or all four colours at
once.
Cleaning the print head consumes ink.
Cleaning too often uses ink unnecessarily.
CAUTION
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

installing a new Brother original
Innobella™ replacement 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 B
