摘要： An image forming apparatus includes an image member, for example, an endless web photoconductor, and a transfer member, for example, a transfer drum. The endless web is driven by a frictional engagement with a drive roller. A web drive output roller fixed to and rotatable with the drive roller in turn drives an idler roller which drives a drive belt positioned around the idler roller and a transfer drive member. The transfer drive member is fixed with respect to the transfer drum and rotates the transfer drum. The outside diameter of the transfer drive member is maintained equal to that of the transfer drum despite varying ambient conditions, by employing similar materials, for example, employing a similar thickness of polyurethane as the outside layer of the transfer drive member. Thus, the peripheral speed of the transfer drum stays the same as the image member despite a varying outside diameter of the transfer drum as ambient conditions vary.

摘要： An optical LED printhead for hard copy printing using a photoconductive transfer system. The printhead includes a linear array of LED's formed by the side-by-side mounting of modular circuit tiles, each containing LED and driver chips. The tiles are bonded to a backing plate constructed of a material with the same thermal coefficient of expansion as the tiles. Slots at the ends and in the middle of the backing plate are aligned with pins in a heat sink of dissimilar material. Differential thermal expansion between the heat sink and the backing plate is controlled by the slot and pin arrangement to allow relative movement in predefined directions which relieve stress but which do not degrade the alignment of the LED's. A printed circuit board and the backing plate are fastened to the heat sink through spring loaded screws extending through oversized holes. Upon mounting, the circuit tiles are located in a rectangular opening in the printed circuit board.

摘要： Apparatus for controlling the lateral movement of a travelling web to automatically compensate for web conicity and angular deviation of the web velocity vector. A preferred embodiment of the apparatus comprises a steering roller about which a travelling web is at least in part entrained. An assembly supports the steering roller for rotation about its longitudinal axis, and mounts the steering roller for angular adjustment about a caster axis perpendicular to such longitudinal axis at the mid-point of the steering roller. The assembly is, in turn, supported for rotation about a gimbal axis intersecting, and perpendicular to, the caster axis. Lateral movement of a web supported on the steering roller is sensed relative to the steering roller in the direction of the longitudinal axis of the steering roller. The mechanism for sensing lateral movement of the web moves in a corresponding direction to the sensed lateral movement of the web. The sensing mechanism is interconnected with the supporting and mounting assembly for angularly adjusting the steering roller about the caster axis in response to movement of the lateral movement sensing mechanism, in a direction to counteract sensed lateral movement of the web.

摘要： A development station for an eletrostatographic apparatus has an elongate sump for a two-component developer material. A feed screw drives developer material along a tube and through openings in the tube into the sump. A ribbon blender coaxially positioned wtih respect to the tube mixes the developer material, delivers it to a developer applicator for transfer to an electrostatic image, and returns the remaining developer material to the other end of the sump for mixture with fresh toner particles.

摘要： A recording apparatus of the type having an endless movable belt on which an image is formed and transferred in registration to a transfer surface. Registration between the transfer roller and the printhead is provided in part by a sprocket engaging the belt through a series of perforation along an edge of the belt. Prolonged integrity and increased load carrying capacity of the perforations are obtained by having a sprocket drive that drives the belt through its perforations in cooperation with a friction drive for driving the belt.

摘要： An electrophotographic apparatus including an endless photoconductive belt member supported by a plurality of rollers. The photoconductive belt is pivotal about an axis of one of the plurality of rollers for movement into an operational position. Pivoting about the axis, into the operational position, assures that the photoconductive belt will be under tension and positioned accurately in relation to the various process stations of the electrophotographic apparatus. The photoconductive belt is also pivotal about the same axis to a belt replacement position. In the belt replacement position the photoconductive belt is in a slacken condition and positioned for replacement, removal, installation or adjustment with minimal chance of damage to the photoconductive belt or other process stations of the electrophotographic apparatus during replacement, removal, installation or adjustment. In moving into the belt replacement or operational position, other processing stations of the electrophotographic apparatus are simultaneously pivoted about a different axis out of and into operational relation respectively.

摘要： An improved fixing assembly for fixing toners or the like on a receiving medium. The improved fixing assembly having a mechanical wide nip formed by a pair of nip forming belts with at least one of the belts being formed by multiple overlapping loops of cold rolled stainless steel. The ends of the stainless steel are secured to the loop adjacent to each end of the stainless steel. The stainless steel flexible formed belt may be coated and heated. Each belt is driven by a pair of internal friction drive rollers with the drive rollers being driven by a toothed belt engaging the drive rollers. The width of the nip is adjusted by changing the center distance between the friction drive rollers of the flexible belts.

摘要： Document scanner having a drive cable system constructed to provide desired alignment between the cables. The drive cables are wound around cylindrical drive members in a spiral fashion from two securing locations. One end segment of the cable spirals toward the center of the drive member in one direction and the other end segment of the cable spirals toward the center in the opposite direction. During the rotation of the drive member, the cable end segments add and subtract turns without changing the overall axial length or position of the cable winding or the alignment of the cable portions leaving the drive member.
