Abstract:
1. A printing system comprising: a media feeder including a supply tray adapted to store a plurality of asymmetrically thick media sheets in a stack, wherein a first sheet of the asymmetrically thick media sheets is oriented different than a second sheet of the asymmetrically thick media sheets, and a device system adapted to remove said asymmetrically thick media sheets from the stack and move the sheets along a transport path, wherein the different orientations substantially reduce the unevenness of the stack by having a thicker end of the first sheet stacked on a thinner portion of the second sheet; a sensor disposed along said transport path to determine the presence of the asymmetrically thick media sheet; an orientation sensor adapted to detect by a one of a transmissive sensing, a reflective sensing, and a thickness sensing whether the leading edge of the asymmetrically thick media sheet is a thick edge or a thin edge compared to the trailing edge to determine the orientation of the asymmetrically thick media sheet; a vision system adapted to visually determine the location of the asymmetrically thick media sheet in the conveyer system, including any offset, or skew of fifteen degrees, in the location of the asymmetrically thick media sheet along the conveyor system; a controller coupled to the media feeder, sensor, orientation sensor and vision system for generating image placement information specifying a desired location and a desired orientation of an image on the asymmetrically thick media sheets, wherein the image placement information is based at least in part on information from the sensor, orientation sensor and vision system; an image or media adjustment system adapted to generate data to adjust the image or asymmetrically thick media sheet by fifteen degrees to accommodate skew of the asymmetrically thick media sheet and, an image transfer system that receives the asymmetrically thick media sheets from the media feeder and places the image on the asymmetrically thick media sheet in the proper location and orientation based at least in part on information from the controller and the image or media adjustment system.
