US Patent:

RE295140, Jan 10, 1978

Filed:

Aug 20, 1975

Appl. No.:

5/606155

Inventors:

James M. Donohue - Los Alamitos CA
Daniel L. Mueller - Fairport NY

Assignee:

Xerox Corporation - Stamford CT

International Classification:

G03G 1500

US Classification:

355 16

Abstract:

A programming control system for controlling the processing steps of an electrostatic printing machine of the type employing an endless photoreceptor belt. A photoreceptor speed sensitive element in the form of a transfer roller is utilized for resetting on. Iadd. a. Iaddend. complete machine timing cycle of processing operation. This cycle, called pitch is applied to the belt and comprises a predetermined number of electrical pulses some of which control machine events.

US Classification:

355 14

Abstract:

A control system for controlling the processing steps of an electrostatic printing machine including means for generating a series train of clock pulses, means for generating a series train of start or reset pulses and control logic responsive to the reset and clock pulses to generate a plurality of timed control signals for implementing certain of the processing steps. A transfer roller, the linear surface speed of which is synchronized with the moving speed of the photoreceptor, may be used to generate the reset pulses for the successive cycle of processing operation. The intervals between the successive reset pulses, called pitches, are in effect marked by the clock pulses, some of which are used to generate the timed control signals.
