Digital BW, The Print

My 1270 is dying. I'm getting random horizontal magenta lines across my 
prints. I've cleaned, windexed, aligned, changed carts, even came close 
to smacking it a couple of times. Can't get rid of the lines. So I'm in 
the market for a new printer and am considering the R2400. Am I correct 
in thinking that I could use this printer for both my color and B&W 
prints? Could I get a nice sepia tone out of it? Right now I'm using 
the dying 1270 for color, a 1280 for color back-up, and another 1280 
with MIS VMS inks for both B&W and Sepia prints. I would love to get 
down to just one printer for all my printing needs but am probably 
asking too much. 
Can anyone in this group enlighten me as to the possibilities of doing 
it all on the 2400?
Thanks,
Evelyn
