Digital BW, The Print

>>If a grayscale image or an image file with R=G=B is fed into an R800, 
is any
of the Red or Blue used to generate the print?

The R800 creates all its grays (except for the very darkest of them, 
which incorporate black) from color inks, since it has no gray inks. As 
best I can determine it integrates only the Blue into its base 
generations scheme, while holding the red out for saturated reds only. 
So printing only neutral images should use up CMYB and K inks, but no 
Red, except for that used in cleaning. Or course they would be poor 
grayscale prints, in terms of consistant neutrality under differing 
light sources...
