Im getting tired of replacing the drums/toners in my HP 2500 colour laser printer (approx 125$ each color).

I have been googling for HP drum reset circuits for hours but without any result.. can anyone in here help???

Ebay got alot of chips with the counter set to zero. But I wanna make my own with at reset buttom to reset the counter on the chip when my printer say that it is "empty" so I can re-use it.
