Lead Edge Sensor
The Lead edge sensor assembly is positioned just after the input rollers and is housed in a
black delrin machined block. To check the operation of this sensor, insert a piece of paper
between the rollers and feed by hand until the sensor is covered, at which point the Red
LED3 will illuminate on the main control PCB.
Replacement.
1. Open the layside and operator side doors.
2. Remove the top infeed roller.
3. Unscrew the two cap head allen screws and lift the sensor housing out.
4 Replace the sensor with a new unit and retighten the screws.
Reassembly is the reverse procedure.
The crunch sensor is a beam projected across the machine just in front of the blade and
above the paper path, when the beam is broken the machine will stop.
The receiver is housed in the sideplate of the machine and is on the operator side, while
the transmitter is housed similarly but on the opposite side.
1.
Unplug from main control PCB & remove green plug - feed cable through apertures.
