As far as I know the matte black channel and the photo black channel can 
not be used at the same time.  I've suggested that possibility for QTR 
but got the negative reply. This means that the choices are like the 
2200, 7600, 9600.

There are 3 types of 4000's, among them a model with a double CMYK 
inkset. Either they are loaded with different firmware or are set that 
way when the first set of inkcarts are loaded. It would be interesting 
to see whether the double CMYK model allows ones side to be driven in 
CMYK mode and the other in a quad mode. I bet that it isn't possible to 
split the head tasks on that model.
