Used the WIC utility to reset the waste inked counter (after cleaning the pads). Worked perfect! Printer is an Epson XP-710

I just bought five keys and used the first one. It magically worked. Epson XP-422 is back to life. I also took advantage to clean the waste box. This is also important :-)

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)
