I purchased four activation keys total, but I had an issue using one. John at tech support got it straightened out and I was able to complete the install on the printer. Now I can set up the CISS unit for Sublimation printing. I'm very happy, and can testify that this product works to unlock the firmware of your printer. (Epson WF-3720)

Looks ok, working fine, save a lot of time in my case, finding a bad sensor in 15 minutes, but can not read counter information`s. Only can reset.

The method described in program was easy to follow. My only problem was having no computer shortcut. The information which came with the key explained it to me, again no problem. It the reset worked. Best buy I have made this Year!! Gerald

The key you provided worked exactly as advertised and I was able to unlock our PP-100 and resume use. Thank you so much for your response and excellent product!

Merci pour votre service. $10 contre le prix d'une imprimante par an, heureusement qu'il existe des solutions comme la vôtre pour l'environnement et nos portes-monnaies.
