Hi. I tried to reset printer Epson EP-901f (japanese model). I tryed everything possible I could - SCC utility, soft reset,.... so far no luck. Then i bought this and it reset my printer just in second. Thanks for good job. My printer is back to life again. I paid for this printer about $550US. Now I can use it again just for spending extra almost 10 dollars. It\'s worth it. Thanks for your great job. Well done!

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.

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.
