Tips for a great answer:
Brother Laser Printers:
After replacing the drum unit, keep the front cover open (make sure the power is on). Press and hold the "GO" button until all four LED's are lit. Once the four LED's light up, close the front cover. Make sure the drum LED is off. The counter is reset!
Brother Fax Machines:
Open the front cover. Press the CLEAR/BACK button. Press 1, when the display shows accepted.
