Cleaning the scanner A
a Unplug the machine from the AC power
outlet.
b Lift the document cover (1). Clean the
scanner glass (2) and the white
plastic (3) with a soft lint-free cloth
moistened with a non-flammable glass
cleaner.
c In the ADF unit, clean the white bar (1)
and the glass strip (2) with a lint-free
cloth moistened with a non-flammable
glass cleaner.
NOTE
In addition to cleaning the scanner glass
and glass strip with a non-flammable glass
cleaner, run your fingertip over the glass
to see if you can feel anything on it. If you
feel dirt or debris, clean the glass again
concentrating on that area. You may need
to repeat the cleaning process three or
four times. To test, make a copy after each
cleaning attempt.
Cleaning the print head A
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 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.
