  I have modified the firmware of an Epson wf3620 with the firmware key to make the printer run with chipless ink cartridges. The instructions were clear but must be followed exactly in order for the process to be successful. I am very happy with the result as I have the freedom to use oem ink or not depending on my needs. No oem cartridges now work perfectly well. Well done wic utility people. regds, Peter.

  I am amazed! The reset worked on our Epson XP-610 wireless printer without a USB cable connecting the computer and the printer right beside it and below the modem. We are grateful. Now I need to send back the USB cable I ordered; it arrived while we were printing Bible study materials being sent from my wife's Surface Pro in the dining room. The Epson is performing like new! Thank you!
