Hello, I've been ripped off like thousands and millions of others, no doubt? I bought a key for Epson XP-2100 without a chip, but it's not clear what to do. I didn't receive any instructions, and the ones on your website contradict each other! I tried to update the firmware, waited a long time, and finally realised that the firmware wasn't updated! What use is the key I bought? And why am I being asked to reset the counter to zero when I want a printer without a chip? What is the wicreset.exe software for? It doesn't do anything, not even generate a report to find out the firmware number... Licensed to : ALEX ANDREOLI

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!
