  John, On your word and based on testimonials I purchased they reset key. Worked perfect up until this point and even ran it through multiple head cleanings. Artisan 710 running again and saved a lot of money. Thanks.

  When my printer quit working, I ordered a new printer. Then I decided to check youtube to see if anything could be done other than taking it in. That's when I found WIC. This process was so easy, I cancelled my order for a new printer and fixed this on in less than an hour. I ordered new pads and entered the code to reset. Code cost me less than 10 dollars, and 2 sets of pads for 15 dollars. Better than iver 300 for a new printer.
