a method and apparatus for determining and correcting registration skew in an image is presented . in the method and apparatus according to this invention , problems in registration , such as misalignment of images and incorrect registration with a receiving substrate are reduced or eliminated . according to this invention , an addition of a second sensor at the transfer end of the photoreceptor belt and the inclusion of a dynamic skew controller will help solve this problem for the lateral direction registration errors . to this end , this invention provides an image processing device embodied as the dynamic skew controller with an additional belt sensor mounted at the transfer end of the photoreceptor module and a microcontroller to measure and calculate the required adjustments . based on the calculations , the lateral position of images and substrates are adjusted , thus eliminating lateral dynamic registration errors .
