Digital BW, The Print

I've installed the heads and brought the Epson dye  ink into the new dampers. There is 
plenty of ink in the carts and lines and dampers.

Then did the initializing of the head numbers. Then did initial fill. Then cleaned etc.

There is plenty of ink in the lines and dampers but I can get NO nozzle check at all. Not 
even the hint of a nozzle line. This has gone on all day.

I sincerely don't think the pump would choose this particular time to go out. When I do a 
head cleaning the pump sounds like it is working fine. Something in the head is not right I 
guess. Checked it three times.

Any suggestions?
