Cleaning the Sensor Glass and the Rollers

If scanned images have extraneous marks, or if the scanned documents are dirty, the sensor glass or rollers inside the scanner may be dirty. Clean them periodically.

1 Carefully open the upper unit until it stops.

IMPORTANT

When opening the upper unit, do not grasp the roller unit in the center. Doing so may distort the rollers and lead to feeding errors.

Note

The location of the sensor glass and various rollers are shown below.
