Abstract

Synchronization of copier electrophotographic (EP) station operations and photoconductor orientation is accomplished without special timing marks or sensors. Microprocessor controls recognize emitter signal sequences which represent the synchronization position for the system, even though those emitter signals provide control functions other than synchronization. A dedicated emitter or cam pulse is not required to reflect home position. The synchronized EP stations include coronas, illumination lamps, magnetic brush developers, and the like, all operatively interrelated with the location of the photoconductor. Some photoconductor areas are charged, imaged and developed, while others are not.
