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

Apart from the first key that I bought that did not arrive, the next 2 keys I bought arrived (I've only used one so far) so I'll save the other one for next time. Thanks very much for your help. Shelley Hamilton.

The trial key is key (pun intended). It unblocked my EcoTank right away through Wi-Fi. Soon I'll have to buy this key. This software DISABLING of the printer should be illegal. It's programmed to actually brick the device. Unbelievable. Talk about planned obsolescence!
