Absolute lifesaver. Saved me about $100 and 2 hours driving.

Model - Epson SX235 Thanks for your prompt response - I\'ve downloaded the file and can now get on with repairing my printer! You provide a great service - I couldn\'t find this manual anywhere else. Regards, Muchtar

I was sceptical but couldn't find any other method of reseting my Epson P50. Worked perfectly and cost me £7.29 GBP. Much cheaper than a new printer. Many thanks.

Holy crap this is a lifesaver / money saver / mental breakdown saver and just an amazing product. I was on the verge or completing my order for a new printer when I came across this site. Why spend $200. for a new printer when $10. can breathe new life into my old Epson Artisan 835 with CISS. I'm good to go now, just have to get a waste ink system installed and I'm back in business. Thanks.

Printer EP-806AW I bought a clear key because there is a limit on waste ink. It was very helpful because I was able to solve it safely.　Thank you very much.　 （JAPAN　2020/11/07）

It is end of October 2021. I just have bought the second reset key in my printers life. The first one I bought in 2015 !!! That means my printer had already it's life prolonged by 6 years and goes now into the second reset cycle. Keep up the good work to prevent valuable electronic hardware becoming garbage. I never had any trouble in 6 years with the ink waste pad after resetting the counter for the first time.
