Replacing the Rollers and Document Holding Guide
When the rollers start to wear out, document feed errors such as paper jams are more likely to occur.
If document feed errors continue to occur even after cleaning the rollers, purchase an Exchange Roller Kit, and replace the rollers
(feed roller and retard roller) and their covers (feed roller cover and retard roller cover), and the document holding guide.
❏ Exchange Roller Kit
The Exchange Roller Kit is a kit consisting of
replacements for the feed roller, retard roller, and
document holding guide. For details, contact your local
authorized Canon dealer or service representative.
Product name: Exchange Roller Kit
Product code: 4593B001AA
IMPORTANT
• Rollers and their covers, and the document holding guide are
consumable parts. When the total number of pages scanned
with the rollers reaches 100,000 pages, purchase an
Exchange Roller Kit and replace the parts.
(See “Checking the
Page Count and Resetting the Counter” on p. 9-9.)
• When the rollers start to wear out, problems such as paper
jams and improper document feeding become more likely to
occur. If this happens, replace the rollers regardless of the
page count.
• Make sure to reset the roller counter after replacing the rollers.
