When making color copies from glass or print from network I`m geeting a purple hue look in all the colors, black prints are fine. When I print each color mono they are ok. The calibration chart colors look solid except small amount of magenta background. Installed new magenta drum & blade still problem. Only 28k on magenta dev mix did 05 adj. Do I need to change magenta dev mix since it cost so much want to make sure.
