I bought a demonstration Epson Artisan 800 from Office Depot. The waste ink pads were "used up" after just a little use. Your reset software and the manuals for this series of printers. really saved the day. You provide a valuable service to Epson users. Thanks

Changed the waste ink pads with the new ones and used WicReset for reseting waste counter on Epson L382. Received the key without any delay, right after placing the order and paying for it. Worked perfectly. Counter became 0,00%. Great utility!
