    Did u check if it's dumping directly into waste tank

    Are u refilling ? Make sure carts are sealed properly, if not
    Printer will dump to prevent a leak.

    Yes likely just the Printhead however I would check the Number of Days elapsed on them. If you did not get 2 years or so from them, then there is likely another problem, possibly affecting them. An example is the Purge Unit. It Cleans, Caps, and takes care of the Printhead so I would look it over thoroughly if your are not getting adequate use from your PH. Also, never turn your Printer off completely if you can help it. There is a sleep mode that the printer will settle into and barely use any electricity. The reason is, the PH needs to expel some microscopic amounts of ink every once in awhile to stay healthy and not dry up and clog. if you have had the printer off for extended periods of time, the life of the Printhead will be reduced greatly, if you ever get the printhead printing again after a long shut down.
    Finally, I have seen a rare case or 2 where the Main Board was bad and would not let 1 specific color print, and there is a slight chance that where the Ink Tube Assembly connects to the PH via an Overlapping spring system, that one side just isn't creating a seal on the Printhead. No seal, No Vacuum, No ink.
