ABSTRACT OF THE DISCLOSURE A document handling system for use in a document reproducing machine includes an endless belt conveyor for conveying original documents to the platen of the machine. A magnetic sensor magnetically senses the speed of the photoreceptor drum of the machine and maintains the speed of a servomotor which drives the conveyor belt through a servo amplifier at the same speed as the drum, whereby, in a first mode of operation the optics of the machine may be fixed and the original document may be driven across the platen at the speed of the drum. A second larger motor may also drive the conveyor belt, in the alternative, at a higher speed through the servo- motor in a second mode of operation in which the original document is fed at high speed to the platen and there is held stationary and is scanned by moving optics.
