    摘要： A device for enhancing the transport of sheets in a printing machine is constructed upstream of the image transfer station to flatten the paper against the transport belt or drum on which it is riding. An air cushion is generated by expelling pressurized air through an array of holes to provide an air bearing for the sheets as it travels in its transport path. The air cushion is designed to flatten the paper against the belt or drum.

    摘要： A roller assembly is provided with openings in its outer surface for selective communication with a source of vacuum or a positive pressure. The openings may be angled along the roller rotational axis to impart a component of velocity to the paper perpendicular to the tangential roller surface velocity. Additionally, by selectively connecting the openings with sources of pressure and vacuum, enhanced paper alignment is achieved, multiple paper feeds eliminated, transitions between different velocities of rollers completed, or paper reverted so that printing can be achieved on first and second sides thereof.

    摘要： A media path jam clearance apparatus installable in a supporting structure includes media drive mechanisms for moving flexible media through media paths and a rotatable, removable jam clearance element. Within the jam clearance element facing surfaces of guide elements define guide surfaces for media paths, with the guide elements having external surfaces capable of supporting the flexible media as it is wrapped around the external surfaces. A pivotal support element supports and enables rotational movement of the jam clearance element within the supporting structure. The jam clearance element may be partially or entirely extracted from the supporting structure.

    摘要： In accordance with one aspect of the present exemplary embodiment, a universal interface is provided for operatively connecting and feeding sequential copy sheet output of various selectable first sheet processing machines to various selectable second sheet processing machines spaced apart horizontally or horizontally and vertically from the first sheet processing machines by widely varying ranges of horizontal distances. The universal interface includes a frame and a universal interface module providing a sheet feeding path repositionable relative to the frame therethrough, from one side to the other of the module, for transporting the copy sheet output of the first sheet processing machine to the copy sheet input of the second sheet processing machine. Further, the universal interface module includes an integral horizontally or horizontally and vertically repositionable sheet receiving and sheet discharging sheet path ends opening at opposite sides of the universal interface module. At least one of the sheet receiving path end and the sheet discharging sheet path end are independently positionable relative to the other of the sheet receiving and sheet discharging sheet path ends over a horizontal range. In a further form, the universal interface module is bidirectional for a bidirectional paper path. Interdigitated sheet guides are provided for defining the sheet path in the bidirectional modules.

    摘要： A dual-zone steam fuser for a xerographic system includes a ultra-heated first zone maintained at 200-500° C. that quickly heats a paper substrate to an optimal toner fusing temperature (e.g., 120-150° C.), and a second, relatively cool second zone for maintaining the substrate at the optimal temperature during completion of the fusing process. A conveying system conveys the substrate so that it exits the first zone and enters the second zone immediately after the substrate temperature reaches the optimal toner fusing temperature, and is maintained in the second zone for a predetermined fusing operation time period. The gas (e.g., steam) temperatures and timing are selected such that surface condensation is minimized during initial heating, and such that moisture content is normalized at the end of the fusing process.
