Abstract
A system for registration of color separation images on a photoconductor belt in an imaging system operates to detect a position of an edge of the photoconductor belt. The registration system detects the position with the same laser scanner used for forming latent images on the photoconductor belt. The registration system includes a belt steering control system that steers the photoconductor belt based on the detected position to reduce deviation of the belt from a continuous transport path. The registration system also may include a scan control system that, based on the detected position, controls the modulation of laser beams scanned to form latent images on the photoconductor belt. By controlling belt steering and laser beam scanning, the registration system maintains the image quality of a final multi-color image upon transfer of registered color separation images to an output substrate.
