4-2 Removing and Attaching the Rollers

To clean or replace the roller unit or retard roller, remove and then attach the parts as described in

each respective section.

IMPORTANT

Feed rollers are consumable parts. When the rollers start to wear out, paper jams and

misfeeds may occur more often. When this happens, purchase an exchange roller kit and

replace the roller unit and the retard roller.

CAUTION

Do not use excessive force when removing or attaching the rollers. Doing so many

damage them.

Roller Replacement Cycle

When the rollers being used have fed more than 250,000 pages, a roller replacement message

appears on the computer. Purchase an exchange roller kit and replace the roller unit 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. 4-6.)

• For information about the exchange roller kit (roller unit, retard roller,) contact your local

authorized Canon dealer or service representative.
