After replacing the Drum Unit in many Brother printers the printer will still indicate that the drum is near end of life. Like all older Brother printers they sometimes have issues detecting as to wether or not a cartridge or drum unit has been changed. To reset the drum counter on Brother Laser printers such as the "Brother MFC-8460N" simply follow these instructions:
- Open the front cover.
- Press the Clear/Back key.
- Press 1 to reset.
- Close the front cover, pressing firmly until each side clicks firmly into place.
