    • For use with an apparatus for feeding sheets seriatim from a stack of sheets, the apparatus including a feed tube, such as an oscillating vacuum feed tube for example, defining a plurality of ports through which vacuum is effective for acquiring a sheet from a sheet stack and transporting such sheet from the sheet stack, a device for improving sheet separation and friction feed assist. The disclosed device includes at least one clip associated with at least one port of the feed tube. A friction member is secured to the clip and extends substantially radially outwardly from the oscillating vacuum feed tube so as to cause an acquired sheet to assume a corrugated shape. Accordingly, a sheet of the sheet stack, acquired by the feed tube, assumes a corrugated shape to readily separate from the remaining sheets in the stack, and the friction member assists in feeding of such acquired sheet from the stack.
    • 为了与用于从一叠片材顺序送纸的设备一起使用,该设备包括诸如例如振荡式真空供给管的进料管,其限定多个端口,通过该多个端口,真空有效地从片材堆叠中获取片材 并从片材堆叠输送这样的片材,用于改善片材分离和摩擦进给辅助的装置。 所公开的装置包括与进料管的至少一个端口相关联的至少一个夹子。 摩擦构件被固定到夹子上并且从摆动真空进料管基本上径向向外延伸,以使获得的片材呈现波纹形状。 因此,由进料管获取的片材堆叠片呈波形状,以容易地与堆叠中的其余片材分离,并且摩擦构件有助于从堆叠中进给这种获得的片材。

    • Electrophotographic printers and cleaning systems for an electrostatic imaging member are provided. In one aspect the cleaning system has a scraper a mounting holding the scraper so that a free length of the scraper extends from the mounting and a frame positioning the mounting relative to the electrostatic imaging member so that the scraper extends along a holding angle toward the electrostatic imaging member and so that the mounting is separated from the electrostatic imaging member by an extension distance along the holding angle that is less than the free length with the scraper resiliently deflecting to fit within the extension distance to define a working angle where the scraper contacts the electrostatic imaging member. The extension distance is within a range of extension distances that cause the scraper to have a working angle that is within a range of working angles are greater than the working angles of an alternative range of working angles if the scraper were to be positioned within an alternative range of extension distances that is greater than the range of extension distances.
    • 提供用于静电成像构件的电子照相打印机和清洁系统。 在一个方面,清洁系统具有刮刀,其具有保持刮刀的安装件,使得刮刀的自由长度从安装件延伸,并且框架相对于静电成像构件定位安装件,使得刮刀沿着保持角度向着静电 并且使得安装件与静电成像构件沿着保持角度小于自由长度的延伸距离分离,刮板弹性偏转以配合在延伸距离内以限定刮刀接触的工作角度 静电成像构件。 延伸距离在延伸距离的范围内,如果刮刀被定位在替代方案中,使得刮刀具有在工作角范围内的工作角度大于工作角度的可选范围的工作角度 延伸距离的范围大于延伸距离的范围。

    • An electrophotographic printer includes a rotatable member and a carriage rotatable around an axis. Two rotatable chargers are mounted on the carriage, each for charging the rotatable member. A carriage drive rotates the carriage to bring the first charger into contact with the rotatable member and the second charger into operative arrangement with a cleaner, or vice versa. A charger drive rotates the charger in operative arrangement with the cleaner at a speed greater than a selected speed or with a torque greater than a selected torque, and the rotatable member rotates the rotatable charger in contact therewith at the selected speed with the selected torque.
    • 电子照相打印机包括可旋转构件和可围绕轴线旋转的托架。 两个可旋转充电器安装在滑架上,每个用于对可旋转构件进行充电。 托架驱动器使托架旋转以使第一充电器与可旋转构件和第二充电器接触,使其与清洁器成为可操作的布置,反之亦然。 充电器驱动器以与选择的速度大的速度或大于所选转矩的转矩的速度使充电器与吸尘器以可操作的方式旋转,并且可旋转构件使可旋转充电器以所选择的转矩以所选择的速度旋转可旋转充电器。
