Guy gave me an printer Epson Pro 4900. The printhead was completely clogged. Used your adjustment program initial ink charge and got an immediate 100% clear nozzle check. Wish everything was this easy...Thanks

Excellent , i was a bit dubious about buying a key in case it didn't work or that it could be a con , but im very very happy i did get this utility & purchased a key . I used this utility to reset my Epson SX-110 which was giving me the message " ink pads had reached the end of their life " & needed service i ain't paying £49.99 just to have a sponge replaced , so a big THANK YOU for the tool & I WILL TELL MY FRIENDS WHO HAVE PRINTERS ALL ABOUT YOU .

The WIC Utility worked like a charm for our Epson XP-830! Nice to not have to replace the entire printer. It's running again with no problem. Thanks so much for offering this service. WELL WORTH THE $10! Nice to find lil treasures like this that works in favor of the consumer!
