If your Tn2250 or TN2230 doesn’t automatically reset the toner counter on your Brother MFC-7360N printer you may wish to try the following procedure:
Open the front panel of your Brother MFC-7360N or MFC-7860DW Multifunction or Brother MFC-8480 laser printer.
Press the Clear/Back button. A display message will then show “REPLACE DRUM? 1. Yes 2. No”.
Do not type 1 or 2, this is not the command you should enter. Instead type *00 on the keypad and you should be rewarded with the word “accepted”.
Close the front door. The toner counter is then reset.
This has been tested on the MFC7360N but should also work on other MFC-7860DW multifunction printer in this series.
