摘要
Correcting motion quality induced color banding problems resulting from photoreceptor motion defects in a color imaging device having a laser based multifaceted polygon (100) and a rotating cylindrical mirror (112) whose rotation is set by a controlled rotation inducing element (150). A motion sensor (200) senses the motion of the photoreceptor. Based upon motion errors a controller (121) either advances or delays the production of a latent image. The controller further controls the rotation inducing element (150), beneficially a piezoelectric element, such that a latent image is produced in a predetermined location. When multiple latent images are produced, the controller beneficially causes the latent images to be properly registered. IMAGE
