Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A bearing for supporting a member in an electrophotographic printing machine of the type having a latent image recorded in a photoconductive drum and for alternatively receiving at least a first shaft and a second shaft is provided. The first shaft has a shape substantially physically different from the second shaft. The bearing includes a body operably associated with the member, a first feature operably associated with the body for supporting the first shaft, and a second feature operably associated with the body for supporting the second shaft, whereby the bearing may accommodate both of the two shafts.

Abstract: A shaft assembly and method of forming a shaft assembly having an elongated hollow shaft with a stepped portion on the surface of the shaft. The stepped portion of the shaft surface is formed of two straight edge sections joined by an inclined section. A gear having a corresponding straight/inclined edge configuration engages the shaft and contacts the shaft only on the corresponding straight edge portions. Both the shaft and gear are made of plastic.
