Abstract

Electrostatographic cartridges having a cartridge base, a toner hopper having a toner fill hole attached to the cartridge base, and a gear housing assembly which blocks access to the toner fill hole and which includes an interior gear housing component integral with the cartridge base are remanufactured by severing the interior gear housing component and then reattaching it to the cartridge base through the exterior gear housing component. Specifically, the one-piece interior gear housing component is severed so that it can be removed thereby providing unobstructed access to the original toner fill hole. Most preferably, the interior part of the gear housing is cut at a five degree angle relative to the cartridge base. The angular cut thereby ensures that the attachment bosses on the cartridge base which serve to couple the base to the toner cartridge cover are not damaged to an extent that would defeat their coupling function. Paired reattachment holes are formed in the interior and exterior gear housing components to allow them to be reattached to one another via screw and nut assemblies extending therethrough. The reattached interior and exterior gear housing components may then be connected to the cartridge base by screws supplied originally with the cartridge by original equipment manufacturer (OEM). In such a manner, fresh toner may be introduced into the toner hopper in a convenient fashion during the remanufacturing operation.
