Today a fuser unit for a brother HL-5250DN should be replaced.
The fuser replacemant was easy but the counter reset was a little bit of a nightmare.
Here are the steps how I was able to reset the fuser counter.
- Download brmainte.zip and unzip the file
- Disconnect the LAN cable and attach a USB cable
- Start the application
- Set the printer to HL-5250DN and read the informations.
Note: The screenshot was taken after resetting the counter.

- Reset the counter
- Recheck the values
- Close the application
- Disconnect the USB cable and reconnect the LAN cable
- Recheck the values on the webinterface

Done, no fuser replacement for the next 100.000 pages 🙂
