Abstract:
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.
