ABSTRACT:
Copy sheets produced by varying copier machine subsystems for analyzing subsystems' performance. By varying parameters, sequencing the coronas, and inhibiting the various subsystems of a copy machine in certain orders, the resulting copy sheets can be analyzed for indications of the subsystems' efficiency. The order of operation reduces or eliminates the subsystems interacting effects so that the degradated operation of a particular subsystem can be perceived.
