Detection Jams (Finisher); Overview - Canon SADDLE FINISHER K3 Service Manual

10 DETECTION JAMS (FINISHER)

10.1.1 Overview

Check timing detects jams in the finisher section. It is stored in the ROM memory of the
finisher controller PCB and uses timing to determine whether or not a jam has occurred
through the presence or absence of a sheet in a sensor section. When a jam occurs, the fin-
isher controller PCB informs the host copier of the details by code. The code can be con-
firmed in service mode in this machine. Also, the jam code may be confirmed with the
LED101 on the finisher controller PCB.
