Great product!
I own a Epson XP-830 printer. It was locked up with the notorious "The printer's ink pad is at the end of it's service life" on the screen. So here I am with new cartridges that I can't use and looking at paying three times as much as what I paid nine years ago for a new printer without all of the features that this one has. After replacing the waste tank I went thru the procedure to clear the printer alert. I had to use a cable with a USB on one end for my HP laptop and square plug on the other end to connect to the printer. Note; follow the procedure carefully. I was in too much of a hurry and it failed the first time thru. The second time did the trick. Don't worry though, the "key" isn't lost until you see the words "Success"!
Great product and fixed for about $20 including the key and new tank.
