Chapter 5 Troubleshooting
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.60.)
• If MICR characters cannot be recognized correctly after
cleaning the heads, the MICR heads may be worn.
Contact your dealer or Canon service representative.
• 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-180II. (See “Cleaning the Ink Heads and Ink
Absorber,” on p.62.)
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
Heads and Ink Absorber,” on p.62.)
