Digital BW, The Print

I am new to B & W printing.  I have an Epson R220 set up with MIS R2N
Cart-set inks.  The issue I have is that the black-black portions of
the prints is coming out flat-black � almost as if a coating had been
scraped off the photo.  I have tried printing with a couple of
different papers and I am still having the same problem.  Any ideas
about what might be wrong?

Also, my primary interest is landscape photos.  What paper do you
recommend using with the MIS inks?

Thanks,

TEF
