ABSTRACT:
Correcting color banding problems resulting from facet-to-facet jitter in a color imaging device having a multifaceted polygon are corrected by starting each color separation using the same facet. This facet synchronization has been shown to reduce the objectionable color banding. Imaging offsets that result from either advancing or retarding the exposure of a latent image such that the latent image begins with the same facet as other latent images are compensated for using a rotating cylinder mirror whose rotation is controlled by a piezoelectric element.
