ABSTRACT:
The present invention is a method and apparatus for modifying line synchronization signals that drive at least one secondary image exposure device in a multicolor printing or reprographic system. The ability to alter the line synchronization signals enables the accurate registration of a multiple color images on a photoconductor in response to detected photoreceptor motion. More specifically, the first color image is deposited on the photoreceptor using a servomotor control system to control photoreceptor velocity as a function of the desired raster line spacing, or the frequency at which the individual raster lines are deposited. All subsequently added colors in the single-pass printing system are added under the control of phase-locked loops, wherein the line synchronization pulses are produced as a function of the photoreceptor speed, to correct for variations from the nominal photoreceptor velocity.
