  Printer is now fixed and working fine. Thank you very much for your help. (I have already \"recommended \" your site to a friend who was having a problem with his printer. Further if (when) I have a problem with any of my other printers, (Canon S600 and Cannon i560), if a manual is needed, I will revisit.

  Today my Epson printer stopped working. I have the tool they provide to reset the ink pad counter but it simply reports network error after network error trying to connect to the Epson server.
Since its Christmas eve and I need to print some gifts for my kids I was totally hooped until I found you guys. I just want to thank you for doing what Epson was unable to do. They suck, you rock!

  The reset key worked perfectly. The whole time to purchase a key, download the software, and reset my R2400 was about 5 minutes. Excellent product! Highly Recommended
