the R2400 using Advanced B&W with the default settings of Neutral/Darker.

For those who can read the numbers, here are the results of a Quickread of a
21-step wedge on ISP (sorry I am not going to change inks just to post the
results for matte paper).  You can see how the colour gets very warm in the
middle and very cool as they paper comes through in the highlights.
