Cleaning the Scanner Glass
Scanning items that have excessive amounts of dirt or dust may dirty the glass. To ensure the best
quality scanned item, wipe the scanner glass with a soft clean cloth to rid the glass of dust or other
debris.
If there is any residue on the glass that does not remove with a soft dry cloth try dampening the cloth
with Isopropyl rubbing alcohol.
NOTE: If lines are appearing in scans from the ADF but not from the flatbed, make sure you have
cleaned the area of the flatbed glass that the ADF scans against. This area is at one side of the glass
and has a white reference frame. This is the area of the glass where images are captured as paper is
pulled through the ADF during scanning.
