  Wow, this software really works! I was very reluctant to purchase the reset key, but after taking a few minutes to read all of the instructions and figuring out how to prepare the printer and computer...it was a breeze. Thank you for saving my printer!

  Much easier then I had expected. Downloaded the program, purchased the key, switch off and on the printer and that was it! The printer works again.
