ABSTRACT:
A xerographic marking device includes an intermediate transfer unit, a media transport path and at least one two-color image-on-image (IOI) drum module. Each two-color IOI drum module includes in a process order around a photoreceptor: a) a first charging unit; b) a first exposure unit; c) a first development unit; d) a second charging unit; e) a second exposure unit; and f) a second development unit, wherein the intermediate transfer unit receives a first toned image and a second toned image from the photoreceptor in a single transfer and transfers those toner images to print media to produce a toned image on print media. In various embodiments, specific color pairings are provided.
