I just reset the toner count on my MFC-L2720DW following these instructions I found by googling:
Access Settings: Press the Menu button, then use the arrow keys to navigate to Settings > All Settings > Machine Info > Parts Life.
Reset: Press and hold the # (pound) key until the reset menu appears.
Confirm: Select Drum, then confirm by pressing OK or Yes, and press the Home button. The printer will initialize, and the error message should clear.
The only problem I had was that after getting to the second step in the above procedure, the numeric key pad with the "#" was not visible. Fortunately, after using a function (copy) that displays the numeric pad, and marking where the "#" is located with a bit of tape, I found that pressing and holding at this location did the trick.
that said, if a function like resetting a drum needs the numeric pad, wouldn't it be a good idea for it to be illuminated so it can readily be seen?
