Self Diagnosis; Copier - Canon NP6330 Service Manual

VIII. SELF DIAGNOSIS
The microprocessor on the copier's DC controller is equipped with a function that
checks the condition of the copier (particularly, its sensors). The microprocessor runs a
check at such times as programmed and indicates an error code or executes error auto
power-off or error shut-off upon detection of an error.
