Cleaning the print head B
To maintain 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 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.
