  Thank you so much for the reset. I was able to clean my ink pads, and then using your reset utility, reset my printer and now it works perfectly! So much better than buying a new printer!

  I got the flashing lights and Service required message on my Epson R2400, as many others have before!
I spent hours online and eventually managed to download Epsons own Adjustment Program. It showed me the waste ink settings but would not let me reset the counter, although I had disconnected the feed tubes and re-routed them to an external bottle.
Today I found and downloaded their WIC reset program. I thought It probably won\'t work but one key is only $9.99 so what the heck!
Well that was the best $9.99 I have ever spent - as soon as I entered the key and hit RESET the printer whirred into action, ink pumped into my waste bottle and I am back in action!

This has saved me a lot of money and the hassle of sending the printer to an Epson service centre. Truly a 5***** product! Chris Porteous, Prestatyn, U.K.

  Спасибо. Все скачалось то что нужно!
  Brian Bloomer 2011-04-30 05:19:44  
  Success! I installed a OctInkjet waste inkpad overflow and tried their reset to no avail - they furnished your link. Your reset fixed my RX690 Epson printer within minutes . Ink started to flow into the overflow immediately (just as well it was installed). I did apattern check-all six colours perfect. Thank you Brian

  Thanks soooooo much !!!!! thought my printer was dead until i downloaded the reset utility and got my key. Process over and printer working in minutes. Saved the cost of a new printer. will recommend to anyone and use again if needed, as the service was 5 star plus.

  Thank you so much. After days, weeks of search online (and lots of non working trials), I finally found your website and your reset did work. Fab!
