  I was leery about paying the $9.99 for a key. After speaking to Epson "Specialist" and being told "Your machine must have issues beyond repair, but we can sell you a new one for $190" I decided to go ahead and try this software. A++ I would recommend this to anyone wishing self repair an epson printer. I have a RX595 , I use a CCS and when I received the waste pad error I was heartbroken. I love this printer. I tried bypassing waste pad but still got the error. This software is well worth the $$ Thank you

  Brilliant reset code worked a treat on my old XP-950 after replacing the waste ink pads.

  my epson l3111 is a good printer that i hve been using - thank you for quick solution

  Thrilled to bits - I thought my trusty printer was destined for the scrap heap ( although nothing wrong except it would no longer operate due to "ink pad full") and I would have to buy new, until I alighted on your product . Also if the ink pad actually causes problem tyou advise where I can buy a replacement kit and do it myself. You perform a great service to printer users. Well done!
