CAUTION: Do not use abrasives, acetone, benzene, or fluids that contain these chemicals. Do not spray liquids directly onto the scanner's glass plate or anywhere else in the scanner. The lifespan of the glass plate depends on the paper types that pass across it. Abrasive papers such as mylar may cause premature deterioration. 5.
