The printer activation failed and I was asked to buy another key, and the key I paid for was used on April 2nd.

It worked on my MX892 !!! Thank you. It reset the Ink Absorber Counter, and my printer was alive again.

Have had series of 8 Epson Printers. Artisan 837 had over 12700 printed pages and 4000 4x6 photos when it gave up the ghost with \"inkpads have reached end of life\" error.
I spent hours with Epson Support level 2 and they were very nice. Printer \"out of warranty\" so how about a new one. Went to Amazon and Bought Epson Expression 860.

Epson support said take Artisan to Epson Authorized Repair Center....I did. They said \"it\'s out of warranty, we can\'t waste the time (or money) trying to fix it!!\"

Used Epson Reset key from Epson 10 times and each time it , the error on inkpads, recurred. The Epson Utility does not do diagnosis like WIC Reset Utility!! Bottom line...Fixed my own machine for very small price and I am ECSTATIC! Thank You, Thank you and Thank you!! Very Happy in San Diego

After an initial trial and after seeing that it worked, I bought a reset key. Works great! 10/10

I was a bit too quick to get going and installed the key into the wrong printer; hence I had to purchase another key! Anyway, the second one worked a treat and I thank you for your efforts, even if it did cost me $19.98! Raymondo

I found the problem, why the reset diidnt work. it was in depending of the epson status monitor. I was going to the task manager and stopped the status monitor. The problem was \\\"The printer statut manager\\\" After stopping status monitor, the reset was work probably. Thanks

My Epson 1280 started getting the dreaded flashing panel lights. The printer quit working all together. I found on the web, that the cause was the ink waste counter had topped out and the printer required service to reset the counter. Then I found this site and downloaded the manual and the service application. Ran the program and quickly reset the counter now all is well again! Worked like a dream. Thank you!
