Abstract
A xerographic copying/printing machine in which the photoreceptor has a row of discrete image marks along one side margin, a CCD type array spaced opposite to and aligned with the row of photoreceptor marks to provide successive blocks of image signals representing the instantaneous pattern of marks viewed by the array on each scan, a light bar spaced opposite the other side of the photoreceptor and aligned with the array for illuminating the array sensors through the marks, and a circuit for converting the image signal output of the array to clock signals representative of photoreceptor speed and position.
