HP Designjet T2300PS - Won't print Magenta

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.
