After changing a drum unit in a Brother HL-L6250DN, the printer’s page count needs to be reset. This will turn off the drum warning on the printer.
Ensure the printer is switched on.
Open the cover on the front of the printer.
Press and hold the OK button for around two seconds.
The Drum Unit option should now appear.
Press the Up Arrow Key to reset the drum counter.
Close the cover on the front of the printer.
