Designjet 9000

I have a very strange problem with my Designjet 9000, as soon as I start printing all printheads start to drop nozzles and soon it starts to print blank as if there is ink starvation, I cancel printing and run IQ test (without cleaning) and it comes out perfect, I repeat the IQ test for 5 or 6 times and still perfect, I start printing again and ink cuts out after less than 5 cm.

Replaced USB cable, replaced the RIP computer, used another RIP software and another computer still the problem exists.

Is the "IQ" test a nozzle check? Partially clogged carts or ink channels have been known to successfully deliver a light ink load for a nozzle check, but still cause starvation when asked to deliver a normal ink load.

The IQ test consists of a solid block (100%) ink coverage of each color 5x8 inch, so it needs much more ink flow than any other print job.
