Abstract: Modification of process control signals so as to enable electrostatographic reproduction apparatus, including a dielectric support member transported about a path into operative association with electrographic process elements to form an information reproduction on a receiver member and a process controller for receiving and sending appropriate timing control signals in an expected value range for controlling the electrographic process, to operate over an alternate process range. For the desired signal modification, an input signal in a particular value range is received. A predetermined gain is applied to the received signal, and thereafter a predetermined offset is applied to the signal as modified by the gain application. The signal derived by gain application and offset is then emitted at an alternate value range to effect process control.

Abstract: A cleaning station for removing the residual toner from a dental x-ray sized photoreceptor plate after the image has been developed. The station comprises two sets of donor and foam cleaning rolls. The cleaning rolls are for removing toner particles from the plate, and the donor rolls are for transporting the cleaning liquid from a liquid delivery system to a nip between each donor and cleaning roll to create a standing wave of liquid at the nip and to flush away the toner particles.
