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
(Yellow/Cyan/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.

call Brother Customer Service. (See
