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.

I own an Epson Artisan 700- Prior to buying it I never heard of the issue with the waste ink counter and epson's built in error codes that render the printer useless after reaching a certain print count. I like a lot of you searched for fixes online. I happened upon (2manuals.com) by way of youtube. I was very reluctant about using this but I also didn't have many other alternatives short of giving in to Epson and their repair method and cost or the purchase of another printer. I am very pleased that I went this route because my printer is up and going (printing) like it should be. I am a very satisfied customer. Thanks, Tim P.

I saved the printer of my boyfriend a few years ago with the trial key and he was so happy that he gifted it to me. Now I decided to give the same printer one more chance and it worked again, saving me 300 euro for the price of 14 within 5 minutes. I also changed the pads by the way did not just reset the software and I recomend you to do that as well. Super easy to use and worth the money! Last but not least a really sustainable solution, allowing us to use a device which otherwise would be throuwn away.

H i 2 m a n u a l s , THANK YOU !!! I just downloaded my WIC reset key, fired up my Epson Stylus Photo 2200 and it works great. This model wasn't on your "works with" list, so you might want to add it. Gary Robert San Francisco
