  All I can say is thank you so much for saving my printer. I changed the ink pads ( very simple task ) and used the Epson Reset. My printer still did not work and I was devastated. I spent MANY hours online researching the problem ( Epson was absoutely no help at all ) and finally came across your product. I used your program to reset the ink pad counter and it reset the counter as advertised. After I restarted the printer It would not do anything. I uninstalled all of the Epson software and reinstalled with the original disk that came with the printer. AWESOME a new printer!!! I can not tell you how much i appreciate your product! I thought I was buying one of the best printers on the market at that time and I am really TICKED off at Epson for building in an unnessisary self destruct. I had purchased every upgrade for my printer Epson offered and was determined to get it working again and you did that for me. THANK YOU !!!!

  Reset my Epson 1430 in a minute. Easy. Had looked around at buying a new printer but really had no time for that anyway. I do not have a waste tank but looking to get one of these soon too. Whew! glad this exists! I was afraid I was in a real pickle.

  It WORKED !!! it was so simple, i just pay for key, and it resolved my problem in few seconds After this reset, I checked my counters and they read 0.00% full. PERFECT !!! You\'ve gained many respect points in my view and I expect repeat business with you.
