  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

  I was amazed how easy that was. I was in doubt that this simple download would work... with my heart racing!

I entered the key,and there it was, all fixed.

2manuals, I must say, what you said it would do, it did, and I\'m so relieved and happy, and can work again.

The success of this has made me want to write a review on your product right away.

Thank you so much
