Cleaning The Image Sensors - GRAPHTEC CS600 User Manual

5.3 Cleaning the Image Sensors

The scanner's image quality drops when the transparent contact plates over the image
sensors become dirty, so clean the image sensors whenever necessary.
Procedure
(1) Turn off the scanner.
(2) Open the top cover as described in Section 5.1 "Opening and Closing the Top Cover".
(3) As shown below, wipe off any soiled areas on the transparent contact plates using
a soft cloth that has been moistened with water or a neutral detergent (diluted with
water) and firmly wrung out.
(4) Completely remove any moisture on the transparent contact plates by wiping them off
again using a soft, dry cloth.
(5) Close the top cover as described in Section 5.1 "Opening and Closing the Top Cover".
Take care not to get your fingers caught in the cover.
Do not use a commercial cleaner for office equipment, a glass cleaner, or chemical
solvents such as solutions containing alcohol.
Although the transparent contact plate is not a maintenance part that requires periodic
replacement, it is a consumable part because its surface may receive slight scratches
due to minute particles of dust and other foreign matter. If document scanning produces
unsatisfactory results (unexpected white or black streaks in the data) due to scratches
on the transparent contact plate or other reasons, please perform the calibration
procedure (see Section 5.6, "Calibration"). If the scanning results do not improve after
calibration, the transparent contact plate(s) will need to be replaced.
