摘要：
A jam detector circuit for use in a photocopier employs feedback and visual indication circuitry for providing a stable and easily adjusted detector. Feedback is provided to desensitize the circuit to sensing device operating parameters which vary according to and within manufacturing specifications. The visual indication circuitry allows a predetermined range of signal change to be defined thereby enabling easy "set-up" of the circuit without the need of electrical metering apparatus.
