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.

Thank you SO SO SO much for making this available for Mac. You can't imagine how much hassle you've saved me - trying to get a Windows machine to run a reset utility on... Excellent service altogether. Many thanks from Ireland!
