Bad Roland DX4 Print head

[signpress]

After doing a manual cleaning of the print heads we realized we had broken manifolds. We replaced all the manifolds on all the print heads. Installed all the print heads in original locations and the #1 cyan print head is now printing all jets full spray all the time. We have switched the ribbons from the carriage board to the print head between two of the print heads and the problem is still on the cyan print head.

obviously in the head

ok, just moved the cyan head to the light cyan position and the problem moved with the head, so now i will look into replacing the head

it is messy code, which happened when you insert the head cables. please try again to remove and insert your cables under power off status and see the printing performance.
If not work, please check your headboard.

all cables were connected and reconnected under power off at main switch originally and with each move. After switching the cyan and lt cyan heads the issue moved with the head to the lt cyan position which leads me to believe the issue is in the head itself.
