摘要： An electrostatographic process cartridge detachably mountable into a cavity defined by mated modules forming parts of an electrostatographic reproduction machine. The process cartridge includes an elongate housing having walls defining a front end of the process cartridge, a rear end thereof, and a process chamber; a rotatable endless photoreceptive member having a closed loop path within the process chamber, and an image bearing surface for holding a formed toner image, and being mounted within the process chamber and towards the rear end for contacting a toner image receiving sheet moving along a machine sheet path for toner image transfer. The process cartridge also includes plural electrostatographic process components located along the closed loop path for forming a toner image on, and transferring such toner image from, the image bearing surface to the sheet of paper, a cleaning component for removing and transporting waste toner from the image bearing surface, and a waste toner sump subassembly mounted to an end of the elongate housing for receiving and containing waste toner removed and transported thereto by the cleaning component. Importantly, the process cartridge includes a module handle attached to the rear end thereof for gripping and use by an operator for inserting and removing the process cartridge from the defined cavity, and forming a part of the machine sheet path for contacting and guiding a sheet of paper moving from the photoreceptive member.

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： 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.

摘要： An electrostatographic process cartridge detachably mountable into a cavity defined by mated modules forming parts of an electrostatographic reproduction machine. The process cartridge includes a housing having walls defining a partially enclosed process chamber; a rotatable cylindrical photoreceptive member mounted within a portion of the process chamber and to the walls. The photoreceptive member has a closed loop path within the process chamber and an image bearing surface for holding a formed toner image. The process cartridge also includes plural electrostatographic process toner image forming and transferring components located along the closed loop path for forming a toner image on, and for transferring such toner image from, the image bearing surface; and a cleaning subassembly located along the closed loop path downstream of the toner image forming and transferring components, for removing and transporting waste toner away from the image bearing surface. The cleaning subassembly includes a curved portion of the walls including a blade mounting surface having a plane forming a blade mounting angle with a tangent to the image bearing surface; a cleaning blade mounted to the mounting surface and having a cleaning edge contacting the image bearing surface at a desired cleaning angle for removing waste toner from the image bearing surface; a seal member mounted into contact with the image bearing surface at a point upstream of the cleaning blade so that the seal member, the blade, the image bearing surface and the curved portion of the walls, define the cleaning chamber; and a troughless waste toner transporting auger mounted for rotation without a trough and directly over the image bearing surface within the cleaning chamber for transporting and moving waste toner axially relative to the photoreceptive member and out of the cleaning chamber. The troughless auger has a first end, a second end, and a direction of waste toner movement over the image bearing surface from the first end to the second end a variable pitch for preventing image banding defects from undesirable waste toner accumulations.

摘要： Method for producing a firm, motion-resistant connection between mating surfaces of a male member, such as a shaft or hub, and a female member such as a bore. One or more thin ribs of pressure-deformable composition, such as integral soft metal or plastic, are formed on one of the mating surfaces, which ribs deform and spread between the surfaces when the male member is forced into the bore to connect the members. According to a preferred embodiment, the shaft is the fixed core shaft of a xerographic toner developer roller within a toner cartridge and/or the hub of a bearing support member for the shaft, and the bore is a central core shaft-engaging bore in the hub and/or a hub-engaging bore in the cartridge housing, and the connection is an electroconducting connection providing near-zero capacitance.
