I had printed nozel check only for 1st head is printing, all the rest are not printing I have replace new head cables and change 2 pumps as well. Please see attached picture for nozel check. Any advise would much appreciated.

if there is ink flowing through the heads during cleaning, or if you can pull from the cap with a syringe, the problem would be more electrical. You could check the fuses (on the head board i think) if they are popped or not.
