I have a Canon Pro 9000 Mark II. I had not used it for some time (about six months) and when I started using it again I notice that I was getting a distinctly magenta cast to the greys, particularly noticeable in grey clouds.
No problems with blocked heads, etc. Is it possible for the ink to deteriorate over time if its not used? If not what do you think has happened. I don't recall having a problem like this before.
