Check the scanner glass for dirt and smudges

Over time, specks of debris might collect on the scanner glass and white plastic backing, which can
affect performance. This can cause vertical streaks on copy jobs from the document feeder, and
specks on copy jobs from the flatbed scanner glass. Use the following procedure to clean the scanner
glass and white plastic backing.

1.

Use the power switch to turn off the product,

and then unplug the power cord from the

electrical socket.

2.

Open the scanner lid.

3.

For specks on flatbed copy jobs, clean the

scanner glass and the white plastic backing

with a soft cloth or sponge that has been

moistened with nonabrasive glass cleaner.

For vertical streaks on document feeder copy

jobs, clean the document feeder scanner strip

on the left side of the product with a soft cloth

or sponge that has been moistened with

nonabrasive glass cleaner.

CAUTION:

Do not use abrasives, acetone,

benzene, ammonia, ethyl alcohol, or carbon

tetrachloride on any part of the product; these

seep and damage the product.

Dry the glass and white plastic with a chamois
