If your error message is the same as listed on this page but your Canon Copier model does not match
what is offered on this page there is still a very good chance that this documentation will be accurate and helpful 
with your model. Canon has done an unusually good job of developing consistent self diagnostics among all 
current and recent model copiers.
 

If you are getting an error message that starts with E4-- or E5-- then it is likely
that the code is related to the RDF or document feeder. (info not available)
