Problem Resident applications, such as anti-virus software, are

draining memory resources.

Solution Quit all resident applications.

there is not enough free space on the hard disk.

the hard disk.

USB 2.0.

Hi-Speed USB 2.0 as standard.

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. 25.)

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. 18.

Problem The rollers inside the scanner are dirty or worn.

Solution Refer to p. 71 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.
