For cautions on handling documents, see "Documents" on p. 6. • Documents with rough surfaces may cause a paper feed error to occur. • 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. 13.) Worn rollers must be replaced. Contact your local authorized Canon dealer or service representative to have the scanner serviced. • The Separation Roller gap is too wide. Adjust the Separation Roller gap.
