Abstract: A method for remanufacturing a printer cartridge component is provided. The method provides a printer cartridge component having an assembled organic photoconductor (OPC) drum with a flange portion and a cylinder portion. The flange portion has a cylinder engagement end attached and inserted in a locked position with a flange lock in a first end of the cylinder portion. The method further unlocks the flange lock so that the flange portion is in an unlocked position in the first end of the cylinder portion. The method further secures the unlocked flange portion. The method further removes the cylinder portion from the secured unlocked flange portion to obtain a removed cylinder portion and a removed flange portion. The method further assembles the removed flange portion with a replacement OPC drum cylinder portion to obtain a remanufactured printer cartridge component.

Abstract: The present invention prevents the deterioration of electrophotographic photoreceptor properties due to non-uniform dissolution of the surface of an aluminum substrate or production of hydrates during rinsing or drying from hot pure water in an aqueous cleaning process, assuring the uniformity and stability on the surface of an electrically-conductive substrate for electrophotographic photoreceptor. The resulting electrically-conductive substrate for electrophotographic photoreceptor exhibits an excellent corrosion resistance that can be expected to provide a high environmental stability. Further, the resulting electrophotographic photoreceptor can exhibit improved electrical properties.
