Self Diagnosis - Canon FINISHER - D1 Service Manual

CHAPTER 5 TROUBLESHOOTING
IV. SELF DIAGNOSIS
The CPU (IC101) on the finisher controller PCB is equipped with a self diagnostic
mechanism which checks the state of the machine as needed; upon detection of an error,
it communicates the fact to the copier in the form of "code" and "detail code."
You can check the detail code in service mode or in reference to LED101 on the finisher
controller PCB.
