Since becoming a Canon authorized servicer costs so much and is very
exclusive, it is highly unlikely that any Canon authorized servicer
would risk losing the factory servicer status by loaning out a service
manual which goes against the agreement signed with Canon.

The nearest photo printer authorized service is more than 80 miles away
from us. We use to do Canon consumer electronics and camcorders, but
Canon has since made those all factory depot repair only.

Good Luck
