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!

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

Dear Team WIC, I was ready to buy a new Epson R800 printer today after failing all weekend to get my printer to work despite trying every technique suggested on the internet including the SSC Service Utility that still doesn't work for whatever reason?? Thank you for your help and the printer is working 100% wonderfully again now with your reset utility!!! GOOD is not enough of a rating for your Firm - GREAT is much better *****10/10***** Much appreciate your service :), Ivor.

John, I wanted to thank you for the excellent service you provided to me. My printer is now working again! There is a site based in England called \"fixyourownprinter.com\". If you want I can leave a message on their forum recommending your site. Let me know if you want this.

Good day. I have to clean my printer head EVERY hour. Then it prints fine. Until I leave it for an hour. So this leads to waste pad full and I have to purchase a key every time. Is there another way to go around this problem please? I cannot afford to buy a key every week. =======Reply ======== You have to make 2 things - clean parking station first - then inks will not dry on printhead; - use high quality inks.
