Maintenance

Scanning area

Keep the scanning area clean to avoid dirty
copies or faxes to be sent.
If your documents have black streaks or
appear dirty after copying them using the
ADF, this may be caused by pencil lead
rubbing off the documents and onto the
roller. Clean the ADF scanning area and
roller.

1

Disconnect the power cord from
the machine.

2

Lift the paper stack cover and pull
it out completely.

Make sure the back end of the cover does not
catch the front paper guide.

3

Lower the scanning platform (A) in
the document delivery slot.

4

Gently wipe the scanning glass (A)
and white sheet (B) with a clean,
soft, lint-free cloth moistened with
water.

Do not dampen the cloth too much, as this
may tear the document or damage the
machine.
