Digital BW, The Print

I just switched my 1280 from MIS VM to MIS UT-2/Eboni, using a new, 
prefilled set of MIS CFS carts & tubes. I cannot get clean nozzle 
checks. I did windex-on-pad, windex-under-head, 
windex-nozzle-injection, MIS's de-foaming procedure, several cycles of 
3 cleaning passes followed by three purge prints. For my labors, one 
color is now not printing at all, and the black cart just squirts ink 
on the edge of the page. I must be doing SOMETHING wrong!?
