Digital BW, The Print

Can anyone suggest a good starting point for printing B&W with the 
standard Epson color inks on a 1280 printer? Using Epson matte 
heavyweight paper.

I've tried using the Advanced settings with no adjustment, and prints 
have a definite magenta cast.

I also tried Norman Koren's settings at:

(scroll down until you see a purplish chart headed "Paper, Settings 
(please see disclaimer above)").  I tried that settings for B&W 
prints on Matte Heavyweight.  His settings improve things, but 
now dark tones are a bit greenish, and mid-tones are still magenta.

This magenta problem exists with color prints, too.  On a picture of 
a waterfall, cascading water in sunlight is white, but cascading 
water in the shade is a bit magenta or purple. If anyone has some 
ideas on that, all help gratefully accepted.

Eventually I'll probably just get the MIS VM inks, but right now I 
want to use up the inks I already have, and I have some color I want 
to do.  If I could just use color inks for everything, that would be 
great, but I really don't want to buy $400 calibration software and 
equipment.

Thanks
