Abstract
A remanufactured toner cartridge and related method includes a modified driven gear that is associated with an internal seal removal mechanism. The driven gear is modified so that driving rotational force from a printer is not transmitted to the seal removal mechanism during a post test of the remanufactured cartridge. When the post test is complete a fixing member, which may include a pin, is used to return the modified driven gear to an operational configuration so that when the cartridge is subsequently installed in a printer, driving rotational force from the printer is transmitted to the removal mechanism to remove the internal toner seal, thereby permitting cartridge operation.
