  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!

  I must say that John provided excellent support and customer service to me when I really needed it. I will send people to this site when they have printer issues they want to fix themselves. Way to go, John. Thanks a lot! - Eric

  I purchased the epson adjustment program last night and got to work on it today.
I had a clog in C and it would not clear. I ve had my 4900 for over 2 years and have been able to handle them until now.
I learned about this site from another site that has cleaner for the 4900 and said I need to buy this software first. I bought it and tried it with the epson ink that was in my printer. I ran the adjustment and it cleared C but then there were other clogs. Because they werent clogged before I started, I cleared them the normal way through the printers options. Had they not cleared, I would have ran the adjustment again.
I had tried everything to get C to clear for a week and this program did it in one try!

I would highly recommend this for clearing a stubborn clog. And now it is in my arsenal if I get another one that I cant clear down the road. By the way, it does not work if your printer is networked. Mine was so I had to move a computer into the room with my printer, directly connect to it and install the drivers. Then it work fine.
If you got a clog that you cant fix, just buy it.

  It worked fine. It was just that we didn't know where to start with opening the program. I couldn't get it to install so there was an icon that took us into the whole program. I found out that if I clicked on the one icon it opened the one we needed. The service manual will be of great help for later when the ink absorption pad needs changing. Thanks for your prompt attention. Regards, Ruth
