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 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.

Your Epson C42 Service Program worked a treat to clear the counter. So easy even I could do it

So simple and effective. What Epsom is doing should be 100% illegal as it is predetermined obsolescence. Very pleased with the product and will recommend to everyone!

Reset my Epson 1430 in a minute. Easy. Had looked around at buying a new printer but really had no time for that anyway. I do not have a waste tank but looking to get one of these soon too. Whew! glad this exists! I was afraid I was in a real pickle.

Tried other sites, but they did not work. This one worked like a charm, wish I had found this one first.
