Replace Fuser Message and Reset in the Brother DCP 9045CDN MFC 9840CDW

At 80,000 copies and prints the Brother DCP 9045CDN  and MFC 9840CDW  the fuser hits the end of it’s expected life and the replace fuser message is displayed. I know everybody just wants the information on how to reset the life counter. I’ll get to that later. In this article, I’d like to share what I’ve seen in the past with these machines and how to remove and check the parts when the replace fuser message appears on the display.

Some of the reset life counters are more important than other. I consider the replace fuser  message one of the most important life counters. I just replaced a fuser  in a 8460 for the second time and never had to replace the laser unit. Drums in these machines typically last 5 to 10 thousand more pages than recommended. I’ve replaced fusers  before their time, at the correct time, ans some a little later. I’d say that 95% of the time either the fuser  is showing early signs of wear or very noticeable. So while on the laser message I just say reset and wait till it dies or sounds really bad. The drum I say order one in but wait till your print quality starts to decline. On the replace fuser  message I always tell my customers its best to do it now. If you want to follow  the instructions below and remove the fuser  and check the upper hot roll and bottom pressure roller. The hot roller is light tan and the pressure roller is below and usually orange or black. Check  the hot roller for wear marks around where the separation claws ride against it. If you see metal showing through it needs to be replaced. If the pressure roller is not smooth and is rippled it’s worn and could cause paper jam and print quality issues.

How to Reset the replace fuser message  on the Brother DCP 9045CDN  MFC 9840CDW

I know most people just really want to know what the replace fuser  message means and how to replace it. So here we go. With the machine at a ready state just press the 3 and 9 button together at the same time. This will bring up the Reset Menu if done right. Scroll down to  Fuser. Press OK. You will then be prompted 1. Reset 2. Exit. Press 1 for reset if you are ready to reset it. Also, if for some reason you have to replace the fuser or any part listed in the reset menu you should always reset the counter even if it hasn’t hit its life cycle yet. Otherwise, someone could be replacing the part you put in a few months ago because the end of life message comes up.

  1. Thanks for the Reset instructions.

    I looked into the pricing of the fuser unit and laser unit honestly together it will run about $300 + my own time and effort to replace it.

    Discussed it with my boss and we basically agreed its one of those you are better off just buying a newer printer than spending the time and money to fix this.

    In the mean time, just reset the counters and squeeze as much out of it till we can’t anymore.

  2. I agree with you. I am at the same place with this printer… I have had this printer since 2010? I even bought one on craigslist for the parts a couple years ago. But printers have come down in price but they are definitely not made as well as this printer! We have other printers at the office that have not lasted this long.
