Digital BW, The Print

I have recently purchased 2 Epson 2000P printers from e-bay, and MIS
UTFSN and UTFS inksets along with Photo Black and Eboni. Now, i'm not
sure how to proceed. Any suggestions would be appreciated. My color
printing with the 2000P was very satisfactory, but whi I tried B&W
with the other (which I am dedicating to B&W only) left something to
desire. There was an image, which I had converted to grayscale, of the
lighthouse I had photographed, but the whole thing was a washed out
gray, although there were several different values of gray. As I said,
any help or direction on where to go would be appreciated.
