Abstract:
1. A modular xerographic marking device system, comprising at least one modular xerographic marking device assembled from the following modular components: a common paper transport module containing paper path components that define a paper path through the modular xerographic marking device and convey a sheet of paper from a paper inlet to a paper outlet; an image output terminal cavity of fixed specified dimensions within the common paper transport module, the image output terminal cavity being exposed to a portion of the paper path; and two or more differently configured marking engines, each sized and configured to be provided and mounted within the image output terminal cavity of the common paper transport module to transfer marking material from the marking engine onto paper transported along the paper path, each of the different marking engines including at least one two-color IOI drum module including wherein each of the at least one modular xerographic marking device is assembled from a combination of the common paper transport module and one of the marking engines mounted within the image output terminal cavity of the common paper transport module so that print media transported along the paper path can receive the first toned image and the second toned image from the photoreceptor from each two-color IOI drum module in a single transfer to produce a toned image on print media.
