Abstract:
1. An imaging device for producing multicolor images, the imaging device comprising: a photoreceptor belt; a first imager to generate an output of a first color at a first exposure station on the photoreceptor belt; a second imager to generate an output of a second color at a second exposure station on the photoreceptor belt, the output of the second color corresponding to the output of the first color; the photoreceptor belt configured to pass the first exposure station and the second exposure station in a process path; a first belt edge sensor disposed near the first imager, the first belt edge sensor detecting a first lateral position of the photoreceptor belt; a second belt edge sensor disposed near the second imager, the second belt edge sensor detecting a second lateral position of the photoreceptor belt; and a controller to determine a difference between the first lateral position and the second lateral position of the photoreceptor belt, a location of imaging of at least one of the second imager and the first imager being moved based on the determined difference.
