摘要： A cleaning apparatus and method for removing residual toner from a photoconductor in a color copier. The apparatus includes a magnetic brush for removing color toner particles from the photoconductor as the different color toner particles serially appear at the cleaning station. A detoning roller located proximate the magnetic brush has a portion thereof near the magnetic brush electrically biased to strip charged toner particles from the brush. A plurality of skiving blades serially operate on the detoning roller in accordance with the respective color of the toner particles to remove the particles from the roller. The portion of the detoning roller adjacent the skiving blades is electrically biased to repel the particles to facilitate their removal. Each of the skiving blades is associated with a respective collecting means for collecting color toner particles of a respective color. When toner particles of one color are being removed from the roller, the skiving blades associated with the other colors are moved to a position where they assist in closing off their respective collecting means from receiving airborne toner particles of colors not intended to be collected. The toner particles collected by the cleaning apparatus are therefore sufficiently free of cross-contamination to permit recirculation to their respective developer stations.
摘要翻译：一种用于从彩色复印机中的感光体除去残留调色剂的清洁装置和方法。该设备包括一个磁刷，用于当不同的彩色调色剂颗粒在清洁站处连续出现时从感光体中去除彩色调色剂颗粒。定位在磁刷附近的定位辊具有靠近磁刷的一部分，该电刷被偏置以从电刷剥离带电荷的调色剂颗粒。多个刮刀根据调色剂颗粒的相应颜色顺序地在定影辊上操作以从辊中除去颗粒。与刮刀相邻的分离辊的部分被电偏置以排斥颗粒以便于它们的移除。每个刮刀与相应的收集装置相关联，用于收集各种颜色的彩色调色剂颗粒。当从辊中取出一种颜色的调色剂颗粒时，与其它颜色相关联的刮刀将移动到它们协助关闭它们各自的收集装置的位置，以接收不想收集的颜色的空气中的调色剂颗粒。因此，由清洁装置收集的调色剂颗粒充分地没有交叉污染以允许再循环到它们各自的显影剂站。

摘要： Apparatus for use in an electrographic copier having a plurality of electrographic process stations for forming visible images on the surfaces of discrete dielectric sheets. Such apparatus establishes a predetermined operative interface between a discrete dielectric sheet and an electrographic process station so that the function of such process station is uniformly applied to the surface of such dielectric sheet. The apparatus includes a member for supporting a dielectric sheet, such member having a sheet supporting surface mounted for movement along a path from a location remote from a process station to a location which is a predetermined distance from such station and then away from such station. As such supporting surface moves along such path, an edge of a discrete dielectric sheet is clamped to the member and successive portions of the surface area of such sheet measured from such clamped edge are tacked to the supporting surface of the member as such portions are moved with the supporting surface to the location a predetermined distance from such process station. The moving member thus supports and transports the tacked sheet whereby the function of such process station is uniformly applied to the surface of such sheet.
