❏Cleaning the Scanning Glass and 
Rollers
If scanned images contain streaks or scanned documents 
become dirty, the scanning glass and rollers inside the 
scanner may be dirty. Use the procedure below to clean 
them on a regular basis. 
1.Pull the lock lever toward you and then fully open the 
panel unit. 
 
CAUTION
The open/close movement of the panel unit is linked to the up/
down movement of the document eject tray. Do not press on the 
document eject tray when you open the panel unit. 
 
2.Use a commercially available air blower to remove 
any dust and paper particles that have accumulated 
inside the scanner. 
3.Use a clean, dry cloth to wipe any dirt off the 
scanning glass. 
 
Hint
There is one scanning glass for the front side of documents, and 
another for the back side. Wipe both of them clean. 
CAUTION
Do not spray water or detergent directly on the scanner. Doing 
so may damage precision mechanisms, such as the light 
source. 
IMPORTANT
Scratches on the scanning glass may cause streaks on 
scanned images, as well as feeding errors. If there are 
scratches on a scanning glass, contact your local authorized 
Canon dealer.

2.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.
❏Replacement Method
For details on how to replace the feed roller and retard 
roller, see p. 9-5 and p. 9-6.
Replacing the Document Holding Guide
1.Open the retard roller cover, and pull it out straight.

❏Checking the Page Count and Resetting 
the Counter
Check the page count on the Roller Counter Reset screen 
of the Administrator Setting screen. 
IMPORTANT
The roller counter counts the number of pages fed by replaced 
rollers. Make sure to reset the counter when you replace the 
rollers since this enables a warning telling you when the page 
number limit has nearly been reached and the roller needs to be 
replaced.
1.Log in to the Administrator setting screen. 
 
2.Press the [Roller counter reset] button to display the 
[Roller counter reset] screen.
