This setting determines whether only black (K) toner is used.
Settings can be applied separately for text, graphics, and image data.
Black and gray data is printed using the black (K) toner only, which lessens toner bleeding.
Black and gray data is printed using all four (CMYK) toners. Gradation reproducibility of dark areas improves in comparison to [On].
