When your printer prints for around 20,000 pages, it will prompt you for "Replace Photoconductor" warning on the LCD display and lock the printer. If your Photoconductor unit is still perfectly good, why waste the money for a new one? Just replace the chip.
Qualified for use in: Canon MF8170
Canon MF8170 Drum Reset Instructions:
Replace your old chip with the new chip. Replacing the chip will reset the counter back to zero and you can continue printing.
