  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.

  I was skeptical in using this tool, but to my surprise and delight it worked like a charm using the serial key (trial) for a quick 10%reset of my Epson Artisan 830. Yes, meaning that if you don't buy the key, it will only reset your printer 10% of the way. My counters are now at 89.99% and 90.00%. It states these counters will reach maximum soon. I only wanted to use the fax option of this printer since I bought a new printer with fill tanks that hasn't arrived yet. This product worked perfectly. I wish I knew about it this software tool before buying a new printer......

  This little app is a life saver. Got up at 6 am this morning as I needed to print out some important documents for later today, only to find that all the lights were flashing on my printer. A quick search on the web pointed me to this site and the app informed me that my ink pad was full. A few clicks later and my printer is like new again. Many thanks.
