Need Help Epson F2000 white ink Issue

[djb28]

I have an Epson DTG f2000 ( white edition). I also have an issue with my ink flow.
When I start the printer and do a nozzle check all checks out well. I print a beautiful
T-shirt. But only once! The next tees will be dull to no white ink.

I then need to do a preventative maintenance clean, that takes 7 minutes.
After that cleaning, I can print another shirt. Only one then the white ink disappears
again until I do another cleaning. I do not know what is wrong. I know the head is firing
and all the ink comes out wonderful when it works.

Is this a damper problem or something else?

You have a air leak somewhere, your head is starving of ink during printing.
