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 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: 4593B005
IMPORTANT
• The rollers 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.
