Abstract
An electrophotographic subsystem (130) with on-board monitoring and adjusting capabilities. The subsystem contains a photoreceptor, at least one toner dispenser, a light sensor and a processor. The processor monitors either light received from a light-imaging subsystem which is in the system into which the EP subsystem is inserted, the wear on the photoreceptor, or the toner's composition and amount, or all of the above processes. The processor then sends information either via controllers or directly to various subcomponents as operating parameter settings or instructions.
