  I\'ve downloaded the Epson R1800 manual. At a quick glance this is just what I need to repair/service the beast! Great service at a reasonable price - Thanks

  XP322 ran out of copies and froze up. I read up that it was an Epson device to sell more printers but discovered your site just before treating it to a display of bad temper. The 20% of extra time will make the replacement question easier and i can use my stock of ink up on this 4 year old printer. I may even use your services to zero life the counter as it isn't a bad device really. Thank you so much.

  Worked hassle free with my Epson XP-55 . I am very thankful that you provide the SW tool also for Linux as I have gone Microsoft-free at home. It's cool that you provide a trial license to check out, whether the counter reset works in your setup (I admit I was sceptical). It worked for me and I immediatly ordered the full license. The good thing is: as it is pure SW, it works also on weekends, when you need to print urgently and that stupid printer decided to not let you print any more!

  The printer\'s ink pads are at the end of their service life. The program worked perfect.
