I have been printing fine with my Epson 2200 for months and then all of a sudden the colors go crazy. Greens are sometimes blue or very very dark, some extra green tint in items like hair. I haven't changed any settings or made any changes in the programs I use. One day I am printing fine, the next day the colors are strange with the same print image. I have used the print head cleaning utility with no improvement. My settings are correct forpaper type and with no color correction. Any ideas?
