Jam Sensor (PPS)

The jam sensor (703531-075) is a photointerrupter that consists of a light

emitter, a receptor, and a lever. This sensor is located partway on the toothed

belt. When the paper fold falls on this belt and kicks the lever, the light

passing between the light emitter and receptor is blocked, and the sensor

turns on. This sensor detects improper paper folding. If either the on-time or

off-time of this sensor becomes longer than its corresponding preset

reference value, then an improper folding error is declared.
