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.

Pressing the OPEN Knob from both sides, raise the Upper Unit.
Note
• The location of the sensor glass and various rollers are shown below.
• The scanner has white, 2mm wide shading boards located at the front and
back of the upper and lower sensor glasses. The scanner uses the shading
boards to determine white standards during scanning. Dirty shading boards
can cause stripes in scanned images. Periodically clean them to ensure
good scanning results.
