Hi, I'm just a hobbyist that has used the 1050c for that last few years and never had much trouble. I just a novice and print out simple images on vinyl and polypropylene. Just today the blacks started turning green with magenta color streaks. I have always used photoshop to print with no problems and inks are full and printheads all seem ok. Seems to start turning green after about 1/3 to 1/2 into the image. Could this be software related or printer hardware issue?
