    Hi,
    I'm wondering if anyone experienced this before.
    The Magenta, either the ink or the printhead, has been acting up.

    Before I print the job, I did the nozzle check, it's all good, not perfect, but ok.
    (See Top Pic)

    Print 22x32" poster for about 3 sheets (out of 75!) then the magenta quit firing ink.

    Printhead clean won't help.
    I took out the magenta print head and dip the tip in warm water
    and stick it on a tissue paper, and let the ink flows. (see tissue scan)

    This helps for another 3 sheets, and it stopped again, like doesn't get enough ink supply.
    (See bottom pic)

    Anyone experience this before ? Is it the printhead ?

    Thank you.

    Info:
    Ink fired : 460ml, never been replaced since we purchased it new 2 years ago.
    other printhead usage is 540ml and 770ml, but still works fine.
