摘要： A printing apparatus includes a guide member for directing sheets toward a transfer zone. The guide member defines a set of ribs which hold the sheets above the main surface of the guide member. Thus, any stray marking material which lands on the guide member is relatively unlikely to contact a sheet moving over the guide member.
摘要翻译：打印装置包括用于将纸张朝向转印区域引导的引导构件。引导构件限定了将片材保持在引导构件的主表面上方的一组肋。因此，落在引导构件上的任何杂散标记材料相对不太可能接触在引导构件上移动的片材。

摘要： A magnet scanning device uses a helical scanning technique to scan a cylindrical magnet along a helical path on a cylindrical surface that corresponds to the cylindrical magnet. Based on the magnetic field profile, the device may detect any unacceptable irregularities in the magnetic field and identify a location of the cylindrical magnet associated with the irregularity.

摘要： An electrostatographic printer has a process unit adapted to be removably mounted in a main assembly of an electrostatographic reproducing machine, the process unit including a developement apparatus at which an electrostatic latent image is developed on an imaging member, and a transfer device which causes a developed toner image to be transferred from the moving imaging member to a copy sheet. The development apparatus is contained within a housing of an electrically insulating material, and comprises conductive means adjacent the exit portion of the development apparatus, i.e. the portion from which the imaging member emerges as it moves towards the transfer device. The conductive means includes a conductive coating on the exit portion of the developer housing, and a conductive seal member through which an electrical discharge path is provided. This reduces the tendency of debris to accumulate in the region of the exit portion, and prevents any debris which does accumulate from building up a charge (which would have detrimental effects on the developed image).
摘要翻译：静电打印机具有适于可拆卸地安装在静电复原机的主组件中的处理单元，所述处理单元包括在成像构件上使静电潜像显影的显影装置，以及使显影要从运动的成像构件转印到复印纸上的调色剂图像。显影装置包含在电绝缘材料的壳体内，并且包括邻近显影装置的出口部分的导电装置，即成像构件朝向传送装置移动时从该部分露出的部分。导电装置包括在显影剂外壳的出口部分上的导电涂层以及设置放电路径的导电密封件。这样可以减少碎屑在出口部分积聚的趋势，并且防止积聚的碎屑积聚起来（对显影图像会产生不利影响）。

摘要： In a xerographic development apparatus using a magnetic brush formed from magnetic carrier particles, a magnetic strip disposed downstream of the development zone along the direction of motion of the photoreceptor retains a separate, small brush of carrier particles near the photoreceptor. The brush acts as a barrier separating a flow of “dirty” air (laden with airborne toner particles) upstream of the strip, and a flow of clean air downstream of the strip.

摘要： A photoreceptor assembly and a xerographic cassette for a printing or copying machine, the cassette including a photoreceptor drum, a drum cleaner, a waste toner container, for storing waste toner; and a waste toner conveyor for conveying waste toner cleaned off said photoreceptor drum by the cleaner into the waste toner container characterized in that the waste toner container is positioned in the interior of the photoreceptor drum and is reversibly removable therefrom. The conveyor typically includes a flexible helical wire which acts as an auger. Once filled with waste toner, the waste toner container is removed from the drum and is replaced by a fresh container.

摘要： A cylindrical magnet for a magnetic brush developer unit used in an electrophotographic printing machine is of U-shaped cross section having a cylindrical outer surface, and a cavity through which extends the rotary axis of the sleeve. The material forming the magnet is a moldable plastic containing a comminuted ferrite. The longitudinal, angularly spaced, poles are produced in the material during the molding operation. The magnetic body is bonded to end support members, and it is self-supporting between them.

摘要： A sealing arrangement for a container in which an auger having vanes is disposed in the chamber thereof for moving particulate material stored therein. A threaded sealing member is adapted to engage the auger vanes so as to be driven along the container on rotation of the auger. The sealing member is mounted slidingly within the container but is restrained from rotating about the auger. On rotating the auger, in one direction, the sealing member moves along the auger to a storage position located beyond the auger vanes.
