Snmp for canon printer/copier

I am new to nagios and I am trying to setup snmp monitoring for a canon iR5020. What are the steps i need to take?

I searched for a MIB guessing I will need one, but I can’t find them on Canon’s USA site. Any help would be great.

I think you could find it here, but I think you have to register:
