Absolutely brilliant , this small utility saved me from having to replace my Printer. Had I known of this sites existence previously I am sure it would have saved my Epson 580 which I just through out.

Perfetto! Qualche difficoltà nel registrare la chiave ma dopo mezz'ora dall'acquisto è stata "digerita" dal software! 9.99$ ben spesi!!!

After an initial trial and after seeing that it worked, I bought a reset key. Works great! 10/10

So had my Epson Pro 4900 disconnected from powersupply for about a month and a half, due to new facilities in my studio. Powered it up, printed a nozzle check, and banged my head against the wall! Only magenta and light cyan did appear, and two broken lines of photo black. Did the Windex trick 5-8 times, and at the 16. nozzlecheck, 9 colours appeared, BUT some actually has got worse, the more Windex the head had. Preparing myself on making a stronger brew for the cleaning (a lot of Googling and reading!), I came across the Service Program. Reluctant to spill ~ 150 ml of ink, I first moved along (also, the website seemed shady, however, alot of mentions on various foras). Today I decided \'What the heck, 30 bucks, if it doesn\'t work, I\'ll survive\', so I purchased a license, installed on a laptop (with USB connection instead of network), and chose the option to prime the left channels first - and WOW: EVERY nozzle on that side now fired, and made an (99%) perfect nozzle check. So did the other side, when finished filling the lines again. So: 5 f*cking huge stars from me! :) Thank you for this wonderful utility!
