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.
