  BRILLIANT My Epson T11 stopped working with the ominous 2 lights flashing so I knew it was trouble and yes teh dreaded message came up about internal parts reaching the end of their servicabel life take it to (an expensive) service. Oh dear - A Google search brought up all sorts of so called download links for free re-set software but all of them didn't download the software but kept taking me to weird web sites. I was in despair of finding somethign that worked then came across I thought at first oh dear theres a cost involved. However I though well if it does work it will be worth it. Downloaded the software, plus updates, ordered the re-set key and hey presto a few seconds later the printer was up and going again. It was was every penny of the cost. Dont waste time trying to find so-called free solutions - total waste of time and so frustrating. Pay out for this and save the time and frustration AND it works! No fuss, no messign about no time wasting getting to dubious web site. A big THANK YOU I can highlym unreservedly reccomend this compnay for sorted out knotty printer problems
