Hi Matt I have a problem almost the same but it is not electrical, Half of the yellow head dissapear but if i make trong clean it come again, If you think it is electrical it can be the head board Thanks Ziv
Your right, maybe its a good time to look at the basics. On an HP 9000 you can purchase maintenance kits, these need to be put in every year or two depending on how much you flog the machine.
How long has it been since you've replaced any caps, primers or wipers?

OK, you say that it is not air and that you excluded cables - one thing that is left is PBA!
But how can you be sure that it is not air leak on cappers (seal not good) - this is hard to prove (see), almost impossible!
Only way you can be sure is if the cappers are new! Or if you shut off printer (in this moment fill cap performes), pull capping station downn (by the belt) and move head carriage from it's position - in this way you can see if capper is filled with ink or empty. If it is empty or half full, then you have air leak problem on capper! Ofcourse you do this manually, when machine is powered off! All other is assumption!
