  I purchased one of your keys and ran the software on the Epson Artisan 1430. It worked great, I now have a working printer. You spared me the expense of having to replace my printer. I can\\\'t thank you enough for your service. I have several other printers that at some point will be in need of your software as well. When the time comes I will call on your services again. Thank you so much!

  Really terrific service and rescue manual and a very helpful and approachable team of people. The very small expenditure indeed saved me the price of a new printer.

  Brilliant stuff! Have tried everything over the last few days to reset my R265, and finally found your site! Brought a key, bit of a problem with my email account, tried another one, got the key, reset the R265 AFTER washing out the inkpads, now everything is working as it should. Many thanks.

  Absolutely fantastic. I got the error message and removed the ink pads ans washed them, don't think I got all the ink out though! Then I used this program as a 'trial' and it worked wonderfully, Printing all OK again and I thought I would need to buy a new printer. When it happens again, I will purchase new pads and a reset key - has to be cheaper than a visit to a repair shop or a new printer. Thank you so much
