Image registration adjustment

A method and apparatus for determining and correcting registration skew in an image includes sensors (352,354) for measuring skew of an image transfer belt (350) and the inclusion of a dynamic skew controller (240) to solve the problem for the lateral direction registration errors. To this end, this...

Zusammenfassung:	A method and apparatus for determining and correcting registration skew in an image includes sensors (352,354) for measuring skew of an image transfer belt (350) and the inclusion of a dynamic skew controller (240) to solve the problem for the lateral direction registration errors. To this end, this invention provides an image processing device embodied as a dynamic skew controller with an additional belt sensor (354) mounted at the transfer end of the photoreceptor module and a microcontroller (210) to measure and calculate the required adjustments and feed them to the imaging device (310,340). Based on the calculations, the lateral positions of images and substrates are adjusted, thus eliminating lateral dynamic registration errors.
