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.
