摘要： An electrostatographic process cartridge detachably mountable into a cavity defined by mated machine modules forming parts of an electrostatographic reproduction machine. The process cartridge includes a housing having walls defining a process chamber and a rotatable cylindrical photoreceptor mounted to the walls and horizontally within the process chamber. The cylindrical photoreceptor has a fixed rotational closed loop path within the process chamber. The process cartridge also includes plural process components including a toner image transferring component, a cleaning component, a charge erase light component, a charging component, an imagewise exposure component, and a development component, each acting along the closed loop path for consistently producing high quality toner images. The plural components each have a critical acting position spaced circumferentially along the closed loop path, and the critical acting positions include a 234.degree. position for the toner image transferring component so as to have reliable, precise sheet feeding to an image transfer point, and a short near vertical sheet path; a 0.degree. position for the cleaning component so as to prevent any leaking toner particles from falling backwardly and down, thus contaminating image carrying sheets moving from the transfer point to a fusing module; a 96.degree. position for a ROS beam imagewise exposure component so as to form a latent image effectively with the ROS beam without undesirable curvature effects from a cylindrical profile of the photoreceptor; and a 163.degree. position for the development component in order to minimize dark decay in the formed latent image prior to its development.

摘要： A process cartridge including a housing having walls defining a process chamber and a photoreceptor mounted to the walls within the process chamber and having a closed loop path and an imaging area having a given length. The process cartridge also includes plural process components acting along the closed loop path for producing imaging affects on the photoreceptor for forming on, and for transferring from, the photoreceptor, a toner image. The process components include a charging component that includes a pin-array charge emitting device having an acting region precisely only as long as the length of the imaging area, in order to avoid occurrence of "dark bands" towards edges of a formed and transferred toner image. The process components also include a developer roll for applying charged toner particles to the imaging area. The developer roll has an acting region centered relative to, and extending slightly beyond, each end of the length of the imaging area. Importantly, the process components include a cleaning component that includes a cleaning blade for removing waste toner from the imaging area and an auger for transporting the waste toner in a waste toner flow direction. The cleaning blade has an acting region slightly longer than the length of the imaging area, and that is offset relative to the imaging area in the direction of waste toner flow, thereby enabling the process cartridge to reliably and effectively produce and transfer high quality toner images.

摘要： An electrostatographic process cartridge detachably mountable into a cavity defined by mated modules forming parts of an electrostatographic reproduction machine having a copy-volume capacity limited by a waste toner sump capacity. The process cartridge includes an elongate housing having walls defining a process chamber; and a rotatable endless photoreceptive member mounted within the process chamber and to the housing. The photoreceptive member has an image bearing surface for holding a formed toner image, a conductive layer, and a closed loop path within the process chamber. The process cartridge also includes a high voltage electrostatographic charging device mounted to the elongate frame and along the closed loop path for applying a layer of electrostatic charge to the image bearing surface of the photoreceptive member; mechanisms for forming on, and transferring from, the image bearing surface, a toner image; and mechanisms for transferring the formed toner image onto a substrate. Importantly, the process cartridge includes a waste toner electro-sump subassembly mounted to an end of the elongate housing for receiving and containing waste toner removed and transported thereto by a cleaning subassembly. The waste toner electro-sump subassembly has an elbow shape including an upper arm portion and a generally horizontal forearm portion. The forearm portion includes an extendible distal end, and a near end having electrical harnessless contacts and connectors formed therein, thereby allowing adaptation of the electro-sump subassembly, at the distal end, for use in various copy volume machines within a family of machines, without affecting the critical electrical and functional interfaces, at the near end, with other subassemblies of the cartridge module.
