The Scanner Does Not Turn ON
Feeding Trouble
Condition
A paper jam has occurred.
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. 22.
• 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. 32.) 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. (See “Adjusting the Separation Roller Gap,” on
p. 40.)
Condition
A double feed error often occurs.
Cause and
Remedy
A double feed error may occur when documents with different
thicknesses are mixed.
If the above-mentioned method is not effective or you are using
the CR-L1 scanner, adjust the Separation Roller gap. (See
“Adjusting the Separation Roller Gap,” on p. 40.)
Condition
MICR characters are not recognized correctly.
Cause and
Remedy
• The scanner cannot correctly read MICR characters if the
magnetic heads are dirty. Clean the MICR magnetic heads.
(See “Cleaning the Magnetic Heads,” on p. 34.)
• If MICR characters cannot be recognized correctly after
cleaning the heads, the MICR heads may be worn. Contact
your local authorized Canon dealer or service representative
to have the scanner serviced.
• The MICR text is on the back of the document. Load the side with
the MICR characters face up in the document tray.
Other
Causes
• Some of the MICR characters are scratched or missing.
Splattered MICR ink or toner may also be the problem.
Condition
The imprinter is not printing correctly (missing imprint
dots).
Cause and
Remedy
Ink is clogged in the ink jet nozzle. Clean the ink jet nozzle.
Cleaning the ink jet nozzle is recommended before using the
CR-L1. (See “Cleaning the Ink Jet Nozzles,” on p. 34.)
