  It WORKED !!! it was so simple, i just pay for key, and it resolved my problem in few seconds After this reset, I checked my counters and they read 0.00% full. PERFECT !!! You\'ve gained many respect points in my view and I expect repeat business with you.

  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!

  I was able to reset an ET-4800 using a USB cable. At first I could not reset due to wireless connection but after changing to a USB it worked great. Epson tech support told me a complete lie. When I called, the first tier said it could not be repaired so I had him move me up to next level. That tech support lied to me as well, telling me they recommend getting rid of the printer as it cannot be repaired. Such LIARS!!

  Thanks John I figured it out.. I didn\'t read things as well as I should have.. and panicked a bit. The good news is my Epson 1280 printer is up and running again thanks to your manual. George
