Cleaning the print head

To ensure the good print quality, the machine
will regularly clean the print head. You can
start the cleaning process manually if
needed.
Clean the print head and ink cartridges if you
get a horizontal line in the text or graphics 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.
CAUTION
DO NOT touch the print head. Touching the
print head may cause permanent damage
and may void the print head's warranty.
