Abstract: An additive manufacturing system includes a transfer belt traveling along a belt path. An electrophotography engine positioned along belt path deposits a part material layer onto the transfer belt, and an image transfer assembly positioned along the belt path transfers the part material layer onto a build platform.

Abstract: A media drying system removes a moistening liquid from a moistened medium. A heating member rotatable around an axis has a liquid-blocking layer with an inner surface and an outer surface. A backing layer affixed to the liquid-blocking layer defines a liquid cavity not including the axis. A heating liquid heated above a moistening-liquid boiling point is sealed between the liquid-blocking layer and the backing layer and in contact with the inner surface. A media-transport system transports the moistened medium so it contacts or is entrained around the liquid-blocking member. The moistened medium contacts the outer surface of the liquid-blocking layer, heat is transferred through the liquid-blocking layer from the warmed heating liquid to the moistening liquid, and the moistening liquid is vaporized and removed from the moistened medium.

Abstract: A printer includes first and second marking units for printing respective first and second image planes on a receiver medium. A digital image capture system is positioned between the first and second marking units, and is used to capture an image of a printed first image plane. Image data for the first image plane is compared to the captured image to determine a displacement between a nominal location and an actual location of the printed image data. Corresponding spatial adjustments are applied to image data for the second image plane to reduce alignment errors between the printed image data for the first and second image planes.
