Cleaning the print head

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 if you get a horizontal
line in the text or graphics, or blank spots
where text should appear on your printed
pages. You can clean Black only; Yellow,
Cyan, and Magenta together; or all four
colors at once.
Cleaning the print head consumes ink.
Cleaning too often uses ink unnecessarily.
