ABSTRACT:
An electrostatographic printing system is disclosed as having a document supporting drum and an optical means for scanning a document for exposing the same to a moving photoreceptor belt. The belt and the drum have their surfaces moved in synchronism by a motor drive for each and including a control system devised to sense the relative velocities of the compared velocities of the belt and drum surfaces and to produce a correction signal for one of the motor drives.
