2. Removing and Attaching the Rollers

Follow the relevant procedure to remove and attach the pickup roller, feed rollers and retard roller when you clean or replace them.

IMPORTANT

Feed rollers are consumable parts. When the rollers start to wear out, paper jams and misfeeds may occur more often. When this happens, buy a exchange roller kit, and replace the pickup roller, feed rollers and the retard roller.

CAUTION

Turn ON the power to the scanner to remove or attach the pickup roller. Be careful when working on the scanner when the power is ON.

Do not use excessive force when removing or attaching the rollers. Doing so may damage them.

Roller Replacement Cycle

When the rollers being used have fed more than 250,000 pages, a roller replacement message is displayed on the computer. Buy a roller replacement kit and change the pickup roller, feed rollers and the retard roller.

IMPORTANT

If misfeeds happen often, check the rollers for wear, and replace them if necessary before the message is displayed.

Be sure to reset the counter after replacing the rollers. (See “Resetting the Counter,” on p. 109.)

Contact your local authrized Canon dealer or service representative for information about the exchange roller kit (pickup roller, feed rollers and retard roller).
