Abstract: A photoconductive member for use in a single pass multi-color printing machine is disclosed. The photoconductive member is composed of an inter seam zone having a physical seam. The inter seam zone includes one of a plurality of image-on-image registration marks respective to a particular color latent image formed on the photoconductive member in a single pass. A plurality of interdocument zones is also included on the photoconductive member wherein process control marks are formed. While the inter seam zone is used for monitoring color-to-color registration, the process control marks are monitored to adjust the timing of the printing machine so that copy media synchronizes with an asynchronous placement of the images on the photoconductive member. A single pass, multi-color electrophotographic printing machine architecture uses a vertically oriented photoconductive belt. Transfer of the toner powder images occur at the lowermost portion of the photoconductive belt. The photoconductive belt is elliptically shaped, having a major and a minor axis. N image recording stations are positioned adjacent an exterior surface of the photoconductive belt on one side of the major axis thereof. Nnull1 image recording stations are positioned adjacent the exterior surface of the photoconductive belt on the other side of the major axis thereof. The image recording stations record electrostatic latent images on the photoconductive belt. This architecture optimizes image registration while minimizing the overall height of the printing machine.
