'Faulty printhead' message on new printhead

HP Recommended

Has anyone found a place that sells the older dates for printhead designjet 510? Everyone is mentioning ebay or amazon, but how do I know  if I am getting the older date printheads as suggested by HP? ALso, the link for the firmware HP updated is not working correctly either. I tried as many of you have by using differrent laptops and USB chords because it says it won't connect without one. We even paid a guy to come out and try to fix it and it was a waste of money after I seen these articles of faulty printheads. Does anyone have the correct firmware needed to reconize these printheads or can I call someone?
