QTR-Quadtone RIP

The 7000 printers are much older that the 2200 so some of the 
difference may be
due to dot sizes of the printers.   But unless you are looking at 
prints with a loupe its
usually not a issue.

So I'm not really sure if what you are seeing is a more serious problem 
or not.
Naturally nozzle checks should be checked and correct ink order 
verified.
I'd suggest printing out the 21step.psd file and scanning the results 
so we can see it.
