Documents Do Not Feed Properly

The following are possible causes of a document failing to feed properly.
Check each possible cause.
Problem Static electricity, etc., is causing the pages of the document
to stick together, and they cannot be separated correctly by
the scanner.
Solution
Before you place your document, thoroughly fan the stack of
papers. (See "Placing Documents," on p. 27.)
Problem Attempting to scan a document of a size, thickness, or
weight that the scanner cannot scan.
Solution
Check the size, thickness, and weight of the document. For
precautions concerning documents, see "Documents," on p. 20.
Problem The rollers inside the scanner are dirty or worn.
Solution
Refer to p. 103 and clean the rollers. If the rollers are worn, then
they need to be replaced. Contact your local authorized Canon
dealer or service representative to purchase a roller replacement
kit.

The retard roller and roller unit are consumable components. You need to
replace the pickup roller, feed rollers and retard roller when cleaning does not
appear to improve them. Contact your local authorized Canon dealer and buy a
roller replacement kit and then replace the retard roller and the roller unit.
