Condition
A double feed error often occurs.
Cause and
Remedy
A double feed error may occur when documents with
different thicknesses are mixed. If you are using the CR-
190i II/CR-190i II UV scanner, you can align the
documents using the jogger.
If the above-mentioned method is not effective or you are
using the CR-135i II/CR-135i II UV scanner, adjust the
Separation Roller gap. (See “Adjusting the Separation
Roller Gap,” on p. 57.)
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. 48.)
• 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-135i II/CR-190i II. (See “Cleaning the
Ink Jet Nozzles,” on p. 49.)
Other
Causes
The ink cartridge may be empty.
Condition
Documents get dirty when using the imprinter.
Cause and
Remedy
Ink from the imprinter has been placed on the feed path.
Clean the ink off the feed path. (See “Cleaning the Ink Jet
Nozzles,” on p. 49 and “Cleaning the Feed Path,” on
p. 43.)
