Abstract
A document imaging system incorporates a mechanism for adjusting the speed ratio between the document scanning system and the photoreceptor. A timing belt is connected between an adjustable tapered portion of a drive pulley mounted on the photoreceptor drive shaft and the document scanning system. The portion of the tapered surface on which the belt is frictionally is axially adjustable resulting in a change in the effective diameter of the belt and a change in the scanning speed.
