  • Concurrent welding and severing belt forming process
    Patent number: 7780805
    Abstract: Belt material is wrapped around a small diameter mandrel. Instead of cutting the belt to length, the material is then continued to be wrapped around the mandrel, forming a belt material overlap, and held under tension. An ultrasonic welding horn is then traversed across the width of the belt overlap. As this horn is traversed across the overlapped joint, the horn not only joins the belt material wrapped around the mandrel but, as the trailing edge is held under tension, the horn also separates or severs the trailing edge of the material from the welded seam.

  • Long life cleaning system with replacement blades
    Patent number: 7783210
    Abstract: Systems and methods are described that facilitate replacing cleaning blades employed to chisel excess toner from a photoreceptor surface. For example, a cleaning unit can comprise a blade holder with a plurality of cleaning blades attached thereto, which is rotated (e.g., by an actuator) to remove a used cleaning blade from the photoreceptor surface and position a new cleaning blade against the photoreceptor surface. Blade replacement can be triggered by a detected defect on an output image or by detected excess toner on the photoreceptor surface downstream from the cleaning blade. Additionally, blade replacement can be triggered as a function of blade use (e.g., measured in time, prints, photoreceptor cycles), friction force on the blade, or a combination thereof, to achieve a desired (e.g., low) cleaning unit failure probability.
