I bought one reset key and it hasn't even been a month yet and my printer is already telling me that the ink pad needs service. All of these good reviews that I have read on here is the reason i took a chance and purchased a reset key. I have not been able to use my printer at all. I am highly pissed off that not even a month after purchasing the one reset key and my printer is back at it again. I want a refund or to be able to try another reset code. this is a bunch of B.S. REPLY: Waste counters doesn't have any relation to how much time did user used the printer. Waste counters increase when printhead cleaning is performed. One printhead cleaning takes about 3-4% of waste counter. So if user make 25-30 printhead cleanings - the waste ink counters will reach 100% and overflow. Doesn't depend on time you will make this cleanings - in 1 month or in 1 year or in 1 day or in 3 years. Usually when printer is new and using Epson original inks - -there will be no need to make printhead cleanings. After Epson inks finish - users often buy third party inks - they have not so good quality as Epson and may clog printhead more often. So after Epson inks finish - users make printhead cleanings more often - as a result - after 20-30 printhead cleanings - counters overflow. So - try to make printhead cleanings less often. Only ONE thing what does Reset Key - it resets waste ink pads counters to ZERO. Doesn't matter counters will be reset by yourself using Reset key ($9.99) or by Epson Service Center engineer ($50) - the result will be the same - counters will become 0% Conclusion: use high quality inks!

Reset key itself WORKS, hurrah! 5 stars. BUT . . . it was a struggle to get the download. Our MacBook which is a few years old does not allow the download to be installed because Apple blocks "unrecognized developers." That should be taken care of or a warning should be placed on all promotional materials related to WIC RESET KEY. I was able to get the download onto my old Apple desktop which has not had operating system updates. That's how I finally purchased the reset key. Please tell me why the whole business of the reset key, after replacing the ink pads, is not an example of contrived malicious obsolescence? I was tied up for hours, cursing the Epson company, and a breath away from buying a new printer, adding plastic waste into our environment. I liken my experience to changing a car's oil filter and then needing a code to start the car again.

I always bought the key and it arrived correctly, but unfortunately in my last 3 purchases, the key did not arrive. I already sent an email to support with the order number with the problem, they told me that everything was resolved, but nothing was resolved, and I still don't have the key. very bad and slow customer support, it took almost 2 days for useless response.
