I just picked up a free HP DesignJet 1055CM because the State was dumping it for functional issues, Up getting it it showed the Cyan printhead needing replacement, and along with that. I tried powering it up and it was printing every color but cyan, so i removed the head an inspected it, i noticed lots of ink build up on the head, I cleaned it and reinstalled it.
Now its just dumping Cyan ink EVERYWHERE and it's not from the printhead, from my experience this is caused by the ink feed...
