Abstract: A media handling assembly contains a transport path for driving a document sheet downstream in a process direction. A first side edge extends lengthwise along the process direction. A registration guide edge extends lengthwise along the process direction and is situated opposite the first side edge. The media handling assembly includes at least one nozzle that is arranged proximate the first side edge. The at least one nozzle selectively discharges an airstream transverse the process direction towards the registration guide edge. The airstream drives the sheet against the registration edge guide for side registering and deskewing of the sheet.

Abstract: A 3-D printer includes development stations that electrostatically transfer first and second materials to an intermediate transfer surface. The development stations can each include a photoreceptor supplying the materials to the intermediate transfer surface, and a boosted developer roll supplying the materials to the photoreceptor. The boosted developer roll comprises an outer roll rotating in a first rotational direction to move with movement of the photoreceptor, and a magnetic roll within the outer roll rotating in a second rotational direction opposite the first rotational direction. The magnetic roll comprises alternating permanent magnets. The intermediate transfer surface transfers a layer of the materials to a platen each time the platen contacts the intermediate transfer surface to successively form a freestanding stack of layers on the platen. A bonding station is positioned to apply light and/or heat to the freestanding stack to bond the layers to one another.

Abstract: Layers of build and support material on an intermediate transfer surface are moved past a transfuse station and a platen moves relative to the intermediate transfer surface to contact the platen to one of the layers on the intermediate transfer surface. The intermediate transfer surface transfers a layer of the build material and the support material to the platen each time the platen contacts the layers on the intermediate transfer surface at the transfuse station to successively form a freestanding stack of the layers of build and support material on the platen. The build material has a higher melting temperature than the support material. A support material removal station heats the stack to a temperature above the melting temperature of the support material, but below the melting temperature of the build material, to melt the support material, but leave a 3-D structure made of only the build material.

Abstract: A module is configured to selectively apply release agent to a web having a sequence of printed imaged formed thereon by a printer. The module includes a plurality of dispensers arranged in a cross-process direction across the imaged web. The module detects positions of areas in the printed images and determines whether the amount of ink in the areas meet or exceed a predetermined density threshold. If an area meets or exceeds the threshold, a controller operates a dispenser to apply release agent to the area on the web as the area passes the dispenser. The controller operates the dispensers with reference to image data of the surface of the web.
