My printer is low on all 5 colors of ink, just put in a fresh black ink. It printed several B&W pages (captured images from Google Earth) but the color was more like dark purple not black. I tried converting images to B&W and then printing, I tried printing in greyscale, nothing improved the purple color. It will print Word type documents in black but not images. Now it won't print at all, a message pops up that says the ink is out. It's not out, the black ink is totally full, I just put it in. Why can't I use my color printer to print with just black ink?
