Removal Instructions for the Brother Fuser Replacement of the MFC-8440, 8840, 8220, DCP-8040, 8045

Lots of things can cause you to replace the fusing unit on these old machines. These fusers are built to last but they wear out eventually. On most these machines the main drive gear on the hot roller tends to break as the heat and age cause the plastic to get brittle and crack. While you can just replace the gear, you should give the whole unit a good look. Check for grooves being worn into the surface of the hot roller where the pick fingers and thermistors ride against it. Also, the coating on the pressure roller breaks away from the inner surface leaving air bubbles and an expanded pressure roller that can lead to a fuser that turns hard. If you remove the fusing assembly and see any of these signs of wear you should consider replacing it. Follow the instructions below for easy to understand removal for your Brother Fuser Replacement.
