  I must admit I was very skeptical about all this !!! And above all - There we go, they want the Credit Card details !!!

I don't even know the current exchange rate but proceeded thinking nothing will come of this ....

Within minutes I was sent the RESET CODE along with the RECEIPT FOR PAYMENT !

It worked like a charm !

The FIRST , but definitely not the LAST time I will be using this site !

Thank you !

  Great product. did the trick which always helps. I did watch your video on how you did it just incase i was doing it wrong and found that the video utility didnt look the same as the utility i used ie no Check button so was a bit unsure to start with. But the product is pretty much idiot proof.

  Hi John, I just want to thank you so much for the reset key and software.Ā Ā I paid you $9.99 to get those lights to stop flashing and it the software worked in a matter of minutes!Ā  I really appreciate your service, without it I would have to buy a new printer (which I don't want to do right now!). Thank you again, you provide a great service. Cheryl
