Ok, I have a Canon MX700. I usually print in black and white, but my black ink is still full and the color is almost gone. How exactly do I change it so that when I choose to print it in B&W, it will only use black ink?
I don't have that model, but for my Canon I click the printer icon at the bottom right of the screen and select 'printer settings'. Then on the main printer properties screen that comes up I tick the 'greyscale printing' option. Goodluck.
Thats what I have been using all along, but to make the black, it combines colors, rather than using the black... I don't know this for a fact, but the color ink goes down, though I rarely use color, and the black ink stays at the same level.
