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!

This was quick, easy and effective. Thanks. I'll be buying more reset keys. Quite a bit cheaper than buying a new printer!

IT WORKS! IT WORKS! IT WORKS!

I tried the free reset key through Epson.com but their servers don\'t work anymore and there\'s soooooooooo many errors.
After hours of frustration I paid the $9.99 saying, \"What do I have to lose?\" Just like the other reviews said, you\'ll be all set within 2 minutes.>The reviews have spelling errors (ha ha) so real people are writing them. And to leave this review that I\'m writing, the site made me log in (proving I have an account and truly am a customer that tried it).
Worked on my Epson Stylus CX8400.
