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 have a Epson TX700w printer I contacted epson in Australia for a fix for full ink pads. They were about as much help as an ash tray on a harley. I pulled the pads out joined a hose to the ink drain hose drilled a small hole in the case put the hose through to a bottle on the out side ink pad problem solved. Downloaded the WIC Reset Programe Reset counter job done. The printer is working like a new one. I will never buy another Epson product again. A big thankyou to the Wic Programe you have saved me a lot of money. Bill.

Thank You. I had just bought a new printer and Epson asked to update the firmware...unfortunately in the middle of the update my power shut off. I thought for sure I had deep sixed my brand new device. Even on the Epson website I could not find a manual firmware recover for my printer and OS version...others printers yes, but not this one. I found you website and thought I'd give it a try. Horray, My printer is back working again. While I am not happy to have to pay someone else for something that Epson should have given for free, your price was with-in reason and your software was easy to use.
