Abstract
A system for belt registration for use in an electrophotographic imaging system, which operates to detect a position of the photoconductor belt uses a pulsed light photodetection system disposed adjacent an edge of the photoconductor belt. The photodetection system may be synchronous or asynchronous. The registration system includes a belt steering system that steers the photoconductor belt based on the detected position to reduce deviation of the belt from a transport path. The registration system may also include a scan control system such that, based on the detected position, controls the modulation of laser beams scanned to form latent images on the photoconductor belt.
