Guy gave me an printer Epson Pro 4900. The printhead was completely clogged. Used your adjustment program initial ink charge and got an immediate 100% clear nozzle check. Wish everything was this easy...Thanks

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.

Good morning. I have two questions, if you´re so kind to help me. 1) The expiration date key. Does it mean once we get it, we have a period to use it? Or what the expiration date referenced to? 2) If the printer has a problem and we have to format it again, will the key information lost and we need a new one, or does it be able to be used again?. Many thanks ! Esther
