  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!!

  I don't like throwing something (a printer in this case) away and consuming our earth's resources (buying a new printer) just because Epson make it difficult for me to avoid doing this. I wish Epson would make products that can be maintained by the product owner and this way contributes to the well being of our planet. This reset utility worked 'as described' and now, having cleaned my ink pads, I can get more value from the printer I already own. Thanks for this reset software.
