The One Time FIRMWARE KEY is required for changing printers firmware.

WIC Reset Utility is used to change printers firmware in following cases:

1. Change to Chipless Firmware - it means printer will not need IC Chips on ink cartridges. Ink levels will be frozen to 100% for ever.
2. Downgrade firmware - this is required when NON ORIGINAL ink cartridges are NOT recognized by printer. This is because printers firmware has been updated from Epson server to newest firmware where not original ink cartridges are forbidden to be used. In this case You have to Downgrade firmware back to old.

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 made the mistake of upgrading the firmware in my Epson XP-434. That caused my ink cartridges to not be recognized. I found this WIC Reset Utility after after searching for original firmware version. I bought the key and plugged it into the utility, and bingo 10 minutes later I was up and running. Thanks a bunch 2manuals.com!

Nevermind. Did more research and to resolve the error, aside the firmware downgrade, I removed the ink, unplugged the printer, turned the printer back on, and placed the Ink's in individually pressing done after each ink. Doing this I was able to get it back up and running again. Thanks!

Worked perfectly! Easy to use. Worth every penny. Saved me tons of time and money not having to bring my printer to a service center (3 hours away), and God only knows what they would have charged me. Fixed my printer in a couple minutes for about $10. Highly recommend!
