Replacing Consumable Parts
The feed roller and retard roller are consumable parts.
The feed roller and retard roller wear with scanning. If the feed roller
and retard roller are worn, documents may not feed correctly and
paper jams and double feeds may occur.
When the total number of pages fed by the scanner exceeds the
number of pages for the service life of the rollers, a message
prompting you to replace the rollers is displayed when the computer is
started.
If this message begins to be displayed at startup, purchase an
exchange roller kit and replace the worn parts with the consumable
parts included in the kit (feed roller and retard roller).
