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.

Excellent , i was a bit dubious about buying a key in case it didn't work or that it could be a con , but im very very happy i did get this utility & purchased a key . I used this utility to reset my Epson SX-110 which was giving me the message " ink pads had reached the end of their life " & needed service i ain't paying £49.99 just to have a sponge replaced , so a big THANK YOU for the tool & I WILL TELL MY FRIENDS WHO HAVE PRINTERS ALL ABOUT YOU .
