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.
