I didn't go to the AS center and immediately solved it at home, and I'm using tissue to absorb lung ink! It wasn't a waste of money at all! Thanks a lot!

Paid for Epson Stylus Color 900 service program and afterwards tried to download program from link. Link would only download a HTML file, and not an executable. Left a message from 2manuals to assist me. This is too damn difficult. Why can the link not just download the executable? ============= Just checked - it works fine. Maybe there were server problem at that moment. You have been sent direct link. John.

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 :-)
