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; means for forming on, and transferring from, the image bearing surface, a toner image; and means for transferring the formed toner image onto a substrate. Importantly, the process cartridge includes a non-metallic electrically conductive grounding pin mounted to the frame and in contact with the photoreceptive member for aligning and grounding the photoreceptive member, so as to prevent photoreceptive member discharge current from passing to an adjacent machine imager module forming latent images on the charged image bearing surface.
