Abstract
A method of remanufacturing a toner cartridge includes installing a modified end cap in which a portion of a drive assembly for an internal toner seal removal mechanism has been disabled. With the modified end cap installed, the toner cartridge may be post tested without removing the internal toner seal. When the post test is complete the modified end cap is removed and a non-modified end cap with a functional drive assembly is installed in its place.
