Abstract
A reassembled laser printer toner cartridge and method of manufacture including a cartridge seal assembly in which the remains of an OEM laser printer toner cartridge's toner hopper pull seal strip(s) is left in position, or a substitute conductive strip is put in the same position to simulate the OEM pull seal strip(s) if the OEM strips have been damages or are missing in order to enable a repaired or remanufactured cartridge to cooperate with the printer in detecting measuring and displaying the amount of toner consumed from the cartridge and shut the printer down, once the toner cartridge is empty, and a toner cartridge hopper foam seal strip assembly that covers the remnants of the OEM seal strips and provides a seal to prevent leakage of toner from the re-filled toner cartridge.
