Recently I have had problems with my Epson shifting color on me. I color balance my monitor and then tag my 2200 to that profile. It has worked great until recently. Now I get a definite green cast. I've cleaned the heads. I am trying to isolate what the problem maybe. A week ago I put in a new Magenta cartridge only to have the system say replace the new one. Which I did, twice before I got it to recognize the cartridge. I'm thinking that I may open up the supposedly new cartridge to see if the ink had hardened, perhaps the cartridge got very hot at Atlex before it was shipped to me. So far only the Magenta has been a problem.
