Abstract
An electrostatographic printing system is disclosed as having a document supporting drum and an optical system for scanning a document for exposing the same to a moving photoreceptor belt. The drum has its surface moved in synchronism with the belt by an a.c. synchronous motor and includes 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 the drum motor drive.
