Cleaning the print head B
To maintain good 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
(Yellow/Cyan/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.

improved call your Brother dealer.
