Cause and 
Remedy

• Check to make sure that the size and thickness of the 

document are within the supported range of the 
scanner, and if the quality of the paper is appropriate.
For cautions on handling documents, see 
“Documents” on p. 5.

• Documents with rough surfaces may cause a paper 

feed error to occur.
Scan one sheet at a time in the separation OFF mode.

• Dirty or worn rollers inside the scanner may cause a 

paper jam.
Clean the rollers if they are dirty. (See “Cleaning the 
Scanning Glass and Rollers” on p. 15.) Worn rollers 
must be replaced. Some rollers are replaceable. (See 
“Replacing the Rollers” on p. 24.) If the rollers are not 
replaceable, contact your local authorized Canon 
dealer or service representative to have the scanner 
serviced.

• The Separation Roller gap is too wide. Adjust the 

Cause and 
Remedy

A double feed error may occur when documents with

feed detection mode, if this happens.
