Digital BW, The Print

Just install a MIS CFS with VM quadtones in a new 1160.  Nozzles 
checked out perfectly with the Epsin supplied carts, but now have a 
problem with the new MIS ink/carts.  Printed out about 30 purge sheets 
and about 20 cleaning cycles.  Missing a few bars in one head check 
(upper right had test).  Am getting some minor banding in my shadows, 
otherwise looks promising.  Using the Roark workflow.

How can I fix this?

thanks,

mark
