Thank you so much. You have helped me twice now. Once 2 yrs ago and just today, with the reset key to get my printer going again and I am so happy as I love my printer and it works perfectly and doesn't need to go to landfill. I have emptied the waste ink pads twice now, washed and dried so they will be the next thing I replace soon.

ho ordinato 1 codice online, il codice è arrivato subito tramite mail, l'ho applicato alla mia epson et-4700, ho spento e riacceso la stampante ed ora il contatore segna 0%, ottimo!!! Grazie!!!

Works slick...and why shouldn't they make some $$ for their key and Utility? I appreciate not having to send the printer to Tech support or buy a new one like Epson suggests- when it was a piece of cake to do myself.
