Cleaning the Sensor Glass, Shading Boards, and
the Rollers
If scanned images have extraneous marks, or if the scanned documents are
dirty, then the sensor glass or rollers inside the scanner may be dirty. Clean
them periodically.
1.
Pressing the OPEN knob from both sides, raise the upper unit.
CAUTION
The pickup roller is located in the middle of the upper unit. Do not
hold the protrusion on the upper unit when you open it. Doing so
may deform the pickup roller or cause a feeding error.
Note
The location of the sensor glass and various rollers are shown below.
2.
Use a blower to keep the interior of the scanner free of dust and paper particles.
