Unfortunately the way they mix grays in color mode uses CM&Y for the light 
grays, not gray ink, plus a minimum of CM&Y as Epson and Canon do... so the 
color mode is not acceptable for B&W printing, only the monochrome mode, meaning 
only one tint, no crosstints, and no adjustment of tints, without metamerism 
issues.
