Digital BW, The Print

I have a st of Eboni-6 carts available for my Epson 1400 and would 
like to print with this inkset using QTR.  I was able to set up 3MK on 
an R1800 via QTR, but the QTR/1400 combination has me befuddled 
(easily done.)

How would I configure QTR for a one channel "black only" print on the 
1400?  Conversely, how would I configure QTR for a 6 channel "Eboni-6" 
print?

Thanks very much in advance for any help.
