1604 print problems

[Red Dog]

Having problems getting full nozzle check out of black and magenta.
Changed, dampers, o-rings, print head, capping station, valve in back that fills black ink bladder.
Cleaned and cleaned, out of answers

Ant help would be great

Are there air bubbles in the lines?

 

[Red Dog]

no, they look full

just did a head soak, cleaned around capping station, did strong cleaning,
ink came through lines to holding tank, running some test prints.
I dont know why the nozzle check was still the same

when I changed the head, the ribbon cables went into the connector hard.
one lone wire (wire 1 on inside) seem to lift so i flattened back down and pushed it in.

Would this be a cause???
