Digital BW, The Print

I recently uninstalled a cfs from my epson 1270. It was no longer
printing. Couldnt get a good nozzle check. I reinstalled the regular
carts and the head still isnt printing. Tried several nozzle checks and
cleaning cycles, but no ink is coming out. Any suggestions from those
who have had prior experience with this type of problem?

Thanks in advance.

Mike
