Digital BW, The Print

Eric: go back to the MIS site and find the section about clearing
clogs with a CIS. Follow the directions, repeat: follow the
directions. Don't leave out the step about substituting fresh dye ink
carts. Trust me, it works. 

The substituting of fresh dye ink carts will accomplish two things. 1)
the dye ink clears clogs much better then pigment. 2) that will tell
you if your problem is in the print head or in the carts. It's
possible that everything you are doing addresses the heads when in
reality the problem is in the carts.
