When HL-2250DN can reset this counter by 7x pressing the "Go Button" and suddenly the printer prints back to the supposedly empty toner.
I have now 200 pages printed with my "empty" Toner and the quality of the printouts is still very good.
So
Toner Reset "Go button" is by pressing the 7x sure worth a try!
I do not know whether this any damage can be caused. I do not think, in spite of all the Note: No warranty and at your own risk.
