Dear Team WIC, I was ready to buy a new Epson R800 printer today after failing all weekend to get my printer to work despite trying every technique suggested on the internet including the SSC Service Utility that still doesn't work for whatever reason?? Thank you for your help and the printer is working 100% wonderfully again now with your reset utility!!! GOOD is not enough of a rating for your Firm - GREAT is much better *****10/10***** Much appreciate your service :), Ivor.

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.

I have three Epson R290 Printers and this is the second one i have had to reset. Your system is the best by far and for $9.99 you can't say no. Yes i was able to purchase the waste pads from a place for only $5.00 so now I should be able to keep on printing. Thanks again guys well done.
