Question about Canon PIXMA MP780 All-In-One InkJet Printer
In the middle of printing a large document my printer ran out of the 3e black ink cartridge. I replaced it, but when I went to resume printing only gray and the colors printed - no black. I went and bought another new 3e cartridge and replace the other. Yet, still NO black will print. Every other color and every other feature is functioning fine. HELP!!!!
This may seem obvious but have you tried cleaning and refreshing the print heads? I've had a similar problem with only certain colors and the cleaning seemed to help.
