I purchased four activation keys total, but I had an issue using one. John at tech support got it straightened out and I was able to complete the install on the printer. Now I can set up the CISS unit for Sublimation printing. I'm very happy, and can testify that this product works to unlock the firmware of your printer. (Epson WF-3720)

Brilliant stuff! Have tried everything over the last few days to reset my R265, and finally found your site! Brought a key, bit of a problem with my email account, tried another one, got the key, reset the R265 AFTER washing out the inkpads, now everything is working as it should. Many thanks.
