Abstract: A development system includes a housing configured for accommodating a developer material which includes toner particles. At least one magnetic roller is positioned within the housing to attract the developer material to a surface of the magnetic roller(s). A continuous developer belt is positioned to attract the toner particles from the at least one magnetic roller to a surface of the developer belt. The developer belt is carried on a plurality of developer rollers. One of the developer rollers is positioned adjacent to an image transfer member, such as a belt or drum, with a photoconductive surface. Some of the toner particles are transferred to a latent image formed on the image transfer member to generate a toner image layer, which is applied to a sheet of print medium.

Abstract: A transport item moves in a process direction to transport sheets of media. The transport item is positioned between an inkjet printhead and a receptacle. The inkjet printhead has nozzles. The transport item has openings arranged in a pattern, the pattern of the openings is consistent along all of the transport item, and the pattern of the openings in the transport item aligns at least one opening with each of the locations of the nozzles as the transport item moves in the process direction. The nozzles eject ink through the openings to the receptacle when the nozzles are aligned with the openings. When controlling the nozzles to eject ink through the openings to the receptacle, a controller can control the nozzles to simultaneously eject ink on a sheet of media while ejecting ink through the openings to the receptacle.

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: An image forming apparatus includes a collection system for collecting vapor co-solvents that are a byproduct of liquid ink. In addition, the collection system collects dew condensation from the moist air that is generated by lamps that dry the ink on a substrate. The collection system can be located in an exhaust passage. A condenser is installed in parallel and in front of an exhaust fan in the exhaust passage. The exhaust fan directs a flow of air through the exhaust passage. The collection system also includes a removable waste bottle for collecting the dew condensation and the condensed co-solvents. The exhaust passage bifurcates into an exhaust duct that is located after the exhaust fan and which discharges dry air and a collection channel that is located in front of the exhaust fan and which carries liquid drip off to the removable waste bottle.

Abstract: A registration system includes nip rollers for conveying a sheet in a process direction when the nip rollers are in an engaged position, and first and second sets of omnidirectional rollers arranged perpendicularly to each other, for conveying the sheet in the process and cross-process directions, respectively. The omnidirectional rollers each allow the sheet to slide, relative to the omnidirectional roller, in a direction parallel to an axis of rotation of the omnidirectional roller. The nip-rollers are movable from the engaged position to a disengaged position, in which the first pair of omnidirectional rollers convey the sheet in the process direction. A feedback system includes sensors for determining registration errors of the sheet and a control system controls the omnidirectional rollers to reduce the registration errors in the sheet while the nip-rollers are in the disengaged position.

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 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.
