I have just used this to sort out my Epson printer which was playing up and its a great tool ..... 1) Work directly with CSIC in Epson Stylus printers cartridges (this allow You to reset CSIC counters or disable CSIC). 2) Freeze internal ink counters. 3) Reset internal ink counters even with empty cartridges. 4) Separate cleaning of color and black heads, powerful cleaning mode. 5) Hot swapping of cartridges supported. 6) Resetting of protection counter (even then it is already full). 7) Near 30 different Epson printers supported Go HERE for a more detailed description and download it at the bottom of the page. I hope its as usefull to you as it was to me. (Edit...was not sure where to put this thread...but as my printer is hardware i chose here....if in wrong place just move it on...Thanks).
