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!!

My Epson 1400 got the end of life message and I had already reset it once before so I couldn't use the Epson site to reset it. I remembered this site from years ago and purchased the utility reset and it worked like a charm. Only wish I had not spent $400 on a new printer before remembering your site. Anyways I just did a live video showing that this really works on my youtube channel. More people need to know about this remedy!

Thank you so much. You have helped me twice now. Once 2 yrs ago and just today, with the reset key to get my printer going again and I am so happy as I love my printer and it works perfectly and doesn't need to go to landfill. I have emptied the waste ink pads twice now, washed and dried so they will be the next thing I replace soon.

Fantastic product key that saved me from rushing out and buying a new printer, allowing me to wait for the parts to arrive in order to keep on working! The very best value for money and thank you so much for the service!

Great, for me absolutely great and excellent ! At my first email contact with 2manuals.com I received a fast response to a question about my printer and then I've been spend ~20 $ for the RX420 Printer manual and one RESET- Key , and it works :-) The Printer manual even is absolutely recommend for Technic freaks , escpecially the pictures in the 'disassembly/assembly' --_ section 4.3.10 Waste Ink Pads are useful. Many thanks and regards, Gerd
