after only cleaning the printer (Canon G3400) three times in a short period, the waste counter was on 100% (almost new printer). tried the free tools which you can download to reset the counter, they all didn't work. Finally decided to buy the key here and didn't believe it would work. But it did, i can use my printer again and I am happy.
