OutlineThe Microprocessor (CPU) on the Finisher Controller PCB is programmed to check for jams in the Finisher/Saddle/Puncher (option) at such times as set in advance. It identifies a jam in reference to the presence/absence of paper at a specific sensor. If a jam is found, the Finisher Controller PCB communicates thenature of the jam to the Host Machine in the form of a code (which may be checked in service mode of theHost Machine).Fig. 2-0591. Inlet Sensor Delay Jam (1011)If the Inlet Sensor does not detect the paper 3 times the specified period of time after the paper outsignal was sent from the hooked-up machine.Fig. 2-0602. Inlet Sensor Stationary Jam (1021)If the paper does not pass the Inlet Sensor 3 times the specified period of time after the Inlet Sensordetected the paper's front edge.Fig. 2-061PI1PI10PI1 : Inlet SensorPI10 : Folding Position SensorHost machine delivery signalJam checkInlet Sensor (PI1)approx. 1.5sec.NormalFeed Motor (M1)Host machine delivery signalJam checkInlet Sensor (PI1)approx. 1.5sec.JamFeed Motor (M1)Jam checkInlet Sensor (PI1)approx. 2sec.NormalFeed Motor (M1)Jam checkInlet Sensor (PI1)approx. 2sec.JamFeed Motor (M1)
