Abstract
A method and system for automatically correcting image registration in an image transfer system utilizing a plurality of moving image-forming media on each of which an image is formed in response to a corresponding start-of-page signal, and an image carrier moving past each of the image-forming media and brought into contact therewith in a transfer zone, wherein the image-forming media are driven independently from one another and the timing of the start-of-page signals and/or the speed of the image-forming media are controlled to maintain a fixed relationship between the longitudinal image distortions occurring in each transfer zone and the timing of the associated start-of-page signals.
