摘要： A single-pass color electrophotographic printer includes four imaging stations, yellow, cyan, magenta, and black, on a generally linear path. A toned image in each toner color is developed on an image bearing member or photoconductive drum. A plurality of electrically biased first transfer rollers associated with each imaging station is operative to transfer the developed images from the photoconductive drum to an intermediate transfer member (ITM) belt that travels sequentially past the imaging stations along the generally linear path in a first transfer operation. The image on the ITM belt is transferred to media at a second transfer operation at which the ITM belt passes through a nip between a backup roller and a further electrically biased transfer roller. A servo operation is used to set the voltages on the transfer rollers. Rollers at the second transfer are positioned to direct media downwardly out of the nip to a media transport belt and to a fuser assembly. A reverse roller is provided downstream of the second transfer operation to shift the path of the ITM belt away from the media guide plate and media transport belt. The ITM belt is formed of a resistive material having a uniform thickness and high tensile modulus.

摘要： Each sheet of a stack of media is aligned with a fixed alignment surface prior to being fed towards a process station of a printer by a single pick roll. During the first portion of its cycle of operation, the sheet advancing force of the pick roll, which is offset from the axis or centerline of the sheet, exerts a torque on at least the uppermost sheet of the stack to have one of its sides engage the alignment surface if it is skewed. When the one side of the sheet is not engaging the alignment surface when the pick roll is initially energized, the uppermost sheet's leading edge engages a resilient projection of an insert of a rib, which is offset from the axis of the sheet but farther from the alignment surface than the pick roll. The skewed sheet pivots about the projection, which is formed of a high coefficient of friction material, extending beyond the surface of the rib. During the remainder of its energization, the pick roll advances the sheet towards the process station of the printer.

摘要： An end seal for use in an electrophotographic image forming apparatus uses an array of ridges (or grooves) to urge toner inwardly so as to help prevent toner escape. The end seal works in conjunction with a cleaning blade. The end seal includes a blade pocket for mating with the end portions of the cleaning blade and a middle portion having an array of ridges thereon. The ridges are angled inward to urge any toner trapped therebetween inward away from the end seals, where the toner can be directed to a waste reservoir in a normal fashion. This “snowplowing” action of the ridges helps prevent outward migration of toner, thereby minimizing toner escape. The end seal may be composed of two or more layers of differing materials. There may be an end seal at each end of the cleaner blade.
摘要翻译：用于电子照相图像形成装置的端部密封件使用脊（或凹槽）阵列向内推动调色剂，以帮助防止调色剂逸出。端盖与清洁刀片一起工作。端部密封件包括用于与清洁刀片的端部配合的刀片槽和在其上具有脊阵列的中间部分。脊向内成角度，以迫使其间被夹在其间的任何调色剂从端部密封件中移出，其中调色剂可以以常规方式被引导到废物储存器。脊的这种“下雪”动作有助于防止调色剂的向外迁移，从而使调色剂逸出最小化。端部密封件可以由两层或更多层不同的材料构成。在清洁器叶片的每一端可能存在端部密封。
