  The procedure was easy. I used the trial version, and my printer is now working. I will buy the reset key next time. I recommend this fix. Thank you....

  Having used Epson "reset" utility once, with success on my XP 830, it allowed me a bit more printing time until it just stopped cold. Research found this site. My download from 2manuals was easy as was the entire process and my printer is working once again, no thanks to Epson. I removed the ink pad chamber and replaced the saturated pads with some of my wife's cotton make up pads...Ha ! We'll see how long that lasts. Very similar material. Cheers and thanks for a good product !!

  This app saved my life for my Epson ET 2850 I was skeptical. It was a bit of a hassle at first, but once I figured it out, it worked perfect. So far, I only had to buy a key and did work. I'm very Happy!
