2. The following illustration shows where the rollers are located in the scanner.
Use a roller cleaning paper to clean all of the rollers indicated in the illustration.
Note: Be careful when cleaning the rollers. All of the rollers, except the free rollers, are designed to rotate in one
direction only. Do NOT force the roller to rotate in the opposite direction. Forcing the roller to rotate will damage
it, and cause the scanner to feed pages incorrectly.
