Service Call Errors

Every time you turn on the main unit, the unit automatically per- forms a self-diagnostic test. If the unit detects a problem at power on, or at any other time during operation, it will display a Service Call Error message in the display. A Service Call Error is indi- cated by an error code consisting of an “E” followed by three digits (“Ennn” where “n” indicates a number). This code is dis- played in 2 parts as “En” followed by “nn”. (Eg. “E123” is dis- played as “E1” followed by “23”.)

Follow the procedure below when a Service Call Error occurs.

1.Immediately switch off the scanner and wait several minutes.

2.Switch the scanner on again and check the scanner status.

When a service call error occurs, it is sometimes pos- sible to resolve the problem simply by switching the scanner off for a while and then switching it on again.

If the “E000” (fixer error) is displayed

The service call error “E000” is a printer fixer error. Switch off the scanner and any peripheral units such as the carrier, unplug the power cord and contact an authorized Canon service techni- cian.

When you cannot clear a service call error

Make a note of the error code and the nature of the problem. Then switch off the scanner and any peripheral units such as the carrier, unplug the power cord and contact an authorized Canon service technician.
