  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!

  I was a bit dubious about buying and downloading manual, never having used this site before, but I'm glad I did. With it I was able to sort a problem on my printer. Without it I wouldn't have known where to start. Thank you. Steve Goodey.

  I am amazed! The reset worked on our Epson XP-610 wireless printer without a USB cable connecting the computer and the printer right beside it and below the modem. We are grateful. Now I need to send back the USB cable I ordered; it arrived while we were printing Bible study materials being sent from my wife's Surface Pro in the dining room. The Epson is performing like new! Thank you!

  Oh my golly, I didn't think that would work, but it fixed it in about 30 seconds. Even though I hadn't been able to disable the process monitor thing that it says do first, the reset program still worked instantly when I ran it on an Epson XP-540. If there is one thing that gets my goat in terms of being so unethical both a rip-off financially and environmentally unsustainable, its the way printer companies rip us off. So am super grateful to have found a way round this. For a much more reasonable price than the printer shop told us, and something I could do at home when I needed the printer urgently for work! Thanks so much!

  Fantastico... funziona tutto perfettamente. Grazie mille

  Erittäin hieno asia kun saa tälläisiä nollaus avaimia edullisesti. Paikallinen huolto ilmoitti että tulostin on romua kun mustetyyny tulee täyteen ja tulostin lopettaa toimintansa. Tutkin hieman internetin tietoja ja löysin tämän sivusaton sekä youtube videon. Homma hoitui ja tulostin tulostaa taas. Kiitos paljon!

  At first I thought I was going to have to spend a lot of money and have to spend a lot of time fixing my issue. It was actually the complete opposite, it was very cheap/affordable and super easy to do. They give you all the steps and explain everything very clearly. do not waste your time with dealing with Epson. This was definitely the best decision to make. Will be back when I need to reset my printer again! Thank you 2manuals.com!!!!! To bad there isnt an AMAZING rating!!

  THIS IS A MUST HAVE UTILITY This reset key worked perfectly for my Epson Artisan 800. I tried the Epson reset utility (free from Epson) many times. It would "reset" the counter to "40%", then upon turning printer off - on, it would revert to "0%" with the error message that the inkpads had reached their end of life. This also happened whenever I performed a head cleaning. For those of us who use a CIS (I am not affiliated with inkproducts.com - but have been using their CIS for a couple of years and LOVE the quality and service) - it is imperative to be able to reset this waste ink counter. I should also add, the waste ink pad issue is real - don't expect to simply reset the waste ink counter and go happily on your printing way - you will have a disaster and you will experience frequent head clogging. You MUST use an external waste ink disposal system - either make your own for $5 or buy one. THIS + the reset utility is what enables you to get the true value from your CIS-modified printer.

  It took me a while to actually understand how to locate the Epson Status Monitor 3. It was a simple disable after that and a simple running of the program after that. I am up and running again!!! Thanks.
