Detecting Jams - Canon FINISHER - D1 Service Manual

IX. DETECTING JAMS
1. Outline
The machine checks for jams at such times as programmed in the ROM of the DC controller
PCB, and detects a jam in relation to the presence/absence of paper at a specific sensor.
When a jam is detected, the DC controller PCB communicates the nature of the jam to the copier
in the form of a code. (The code may be checked in the copier's service mode, or by referring to
LED101 on the finisher DC controller PCB.)
