Canon IRC 2100 Service Repair Manual
That is the link to the service repair manual which also has the error codes so you can diagnose what is going on although there doesn't seem to be an E30 code accounted for.

This is a more extended list of all of the error codes and once again there seems to be no E30. There are 9 pages of error codes if you'd like to look.
