Abstract: A method for installing a replacement optical photo conductor cylinder in a recycled toner cartridge having a frame for an electrostatic copier or similar device where the original photo conductor is permanently installed in the frame forming a part of the toner cartridge. The method includes the steps of removing the original cylinder by cutting it into as many segments as is necessary, providing a bushing within the original non-driven socket in the frame, providing the non-driven end of the replacement cylinder with a cap having a bore therein, inserting the replacement cylinder into operative position in the frame, and inserting a headed pin through the bushing and the cap to provide a bearing.

Abstract: A synthetic resinous tear strip seal or toner cartridge used in electrostatic copy machines, in which the longitudinal central area of the strip is reinforced by laminating additional planar material thereto in the area overlying the elongated opening in the toner cartridge, and preferably along at least part of the tear strip. The material may be similar to that of the seal, or of other material selected for electrostatic conductivity to dissipate the electrostatic attraction of the seal material to the toner particles in the toner cartridge hopper. Typically, a thin coating of aluminum is applied to the material which is of a synthetic resin.
