ABSTRACT:
A system for checking copy quality variables within an electrophotographic copier machine involving the production of a developed sample test area and a base reference test area on a photoreceptive surface. An optical transducer is used to view the test area and circuits are provided to produce an output signal indicative of quality. The circuit triggers itself by detecting a substantial change in transducer produced signal level when the sample test area is viewed, thus negating the requirement that the test circuits be operated under the control of the machine.
