LCD-
DISPLAY
To clean the display surface, use a soft lint-free cloth, either dry or
moistened with neutral detergent or ethanol. Do not use any organic
solvents, acid or alkali solution.
Note: If lines appear on the images scanned with the ADF, but not on
the Flatbed glass, the thin plate of glass used by the ADF may be
dirty. When pages are pulled through the ADF during scanning, this
thin glass plate is where the images are captured by the scanner.
