After you change the DR321CL drum unit in your Brother laser, an additional reset must be performed from the printer itself to prepare it for the new item. Once you have done this reset, an internal page counter will be put back to zero. This allows your Brother printer to estimate how much life it has in it more accurately. If you neglect to perform this reset your printer will continue to warn you of ‘Drum End Soon’, ‘Replace Drum‘ or even continue flashing the Drum LED at you. Thankfully, the reset procedure is very quick and easy to follow.
What printers does this reset work for?
