摘要： A developer camming apparatus connected to a developer unit, including a slide, a motor, and an encoder, wherein the encoder determines a distance a developer unit is from the photoreceptor, wherein the encoder allows the developer unit to be sufficiently close to effect application of toner to the photoreceptor from the developer unit, but also does not allow the developer unit to contact the photoreceptor during a print job.

摘要： A developer unit for a color imaging system includes a housing, a developer roll, and a magnetic stripping roll. The housing defines a chamber for holding developer material, which includes toner particles. The developer roll is mounted in the housing and rotates to attract developer material to flow on its surface. The developer roll carries the developer material into proximity to a latent image to create a toner image. The magnetic stripping roll is mounted in the housing and rotates between a functional and a non-functional position in proximity to the developer roll to strip developer material from the surface of the developer roll, cleaning the developer roll. The magnetic stripping rolls may include a magnet assembly with a functional position for activating the magnetic stripping roll and a non-functional position for deactivating the magnetic stripping roll. The magnetic stripping roll may be mounted to shift between two positions.
摘要翻译：用于彩色成像系统的显影单元包括壳体，显影辊和磁性剥离辊。壳体限定用于保持显影剂材料的室，其包括调色剂颗粒。显影辊安装在壳体中并旋转以吸引显影剂材料在其表面上流动。显影辊将显影剂材料携带到潜像附近以产生调色剂图像。磁性剥离辊安装在壳体中并在靠近显影剂辊的功能位置和非功能位置之间旋转，以从显影辊的表面剥离显影剂材料，清洁显影辊。磁剥离辊可以包括具有用于激活磁剥离辊的功能位置的磁体组件和用于使磁剥离辊失活的非功能位置。磁剥离辊可以安装成在两个位置之间移动。

摘要： An apparatus and method are described for extending the life of a photoreceptor in xerographic printing. At a predetermined point in the life span of a photoreceptor, a correction circuit is interposed between the power supply and the charging device of the printer. Correction circuits of different designs can be selected to compensate for the photoreceptor properties at different stages of its useful life. The different correction circuits can be automatically activated over time, or can be retrofitted into a replaceable module when the replaceable module is remanufactured.

摘要： An apparatus in which flowing developer material is mixed. A plurality of spaced vanes project outwardly from a dividing plate to define a plurality of sets of chambers arranged in substantially parallel rows. Each chamber is arranged to receive developer material at an entrance aperture and to release the developer material from an exit aperture with the exit aperture being displaced from a position vertically below its entrance aperture. Each row has an alternate series of chambers with their exit apertures spaced respectively to the left and right of the position vertically below their entrance apertures. The entrance apertures and exit apertures of the chambers of different rows are aligned so that on successive recirculations of the developer material, the developer material moves simultaneously from left to right and from row to row, and from right to left and from row to row.
摘要翻译：混合显影剂流动的装置。多个间隔开的叶片从分隔板向外突出以限定以基本上平行的行布置的多组腔室。每个室被布置成在入口孔处接收显影剂材料并且从出口孔释放显影剂材料，其中出口孔从垂直于其入口孔的位置移位。每排具有一系列交替的腔室，其出口孔分别垂直于其入口孔下方位置的左侧和右侧。不同行的腔室的入口孔和出口孔对准，使得在显影剂材料的连续再循环中，显影剂材料同时从左到右，从一排到另一行，从右到左，从一行移动到另一行。

摘要： A scanning optical system for a photocopier is mounted on a reciprocating carriage which travels between a start-of-scan and end-of-scan position. The carriage is engaged and driven by a drive transmission member which, in a preferred embodiment, is an endless belt having detents spaced along its length. The belt simultaneously drives the support for a photosensitive surface.
