Instructions for the Brother Color HL- 3040CN / 3070CW Fuser Replacement
After 50,000 prints your machine will come up and give you a Replace Fuser Message. At this time I strongly recommend that a new fusing assembly is purchased and installed in the machine. Failure to replace the fusing assembly at this time can lead to a decline in the print quality of the machine. Below you will find the illustrated  Brother Color HL- 3040CN / 3070CW Fuser Replacement procedure. Also, you will find a few links to order in a replacement fusing assembly if you haven’t already order one. Finally, at the bottom of the article you will find a link to the Fuser Life Reset counter to clear the Replace Fuser message once a new one has been installed.
