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. 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.
