Is this about the B9180 ?  The Z3100 in the advanced B&W 
mode allows color toning on top of the neutral grey inks. 
Even color printing has such an extended black generation 
that in practice the light grey ink cart goes first and I 
see no hue dots in lightest steps with the microscope in 
neutral patches of a color print made with the Matte Litho 
Realistic media preset.
