Warning Do not use abrasives, acetone, benzene, or carbon tetrachloride on the glass; they can damage it. Do not place or spray liquid directly on the glass; the liquid might seep under the glass and damage the device.

Note Make sure you clean the small glass strip to the left of the main glass surface. This strip is for processing jobs from the automatic document feeder. Streaks can occur if the glass strip is dirty.
