Digital BW, The Print

Im using piezography k7 inks and whenever i try to print using
QuadtoneRIp with my epson r2400, it just starts printing with all my
ink. It covers the whole sheet with black, im not sure why thats
happening, its like flushing all the ink. It just wants to print the
whole image in black which wastes all my ink. I hope someone can help
me with this, cause the ink is expensive and the paper as well.

the printing set is for the epson r2400 and the settings for the QTR are

image size:10.5x15-300DPI
Paper Brand=Hahnemuhle photo rag bright white 11x17
Paper=Tabloid(11x17)
Printing Model:QuadR2400-K7 
Source=Manual Roll(rear) 
Type=Matte Paper 
Resolution:2880 DPI 
Speed:Better 
Dither Algorithm:Ordered 
Both Curves:K7-2880-HanPhotoRagBrtW 
Ink Limit Adjustment=0 
Gamma Adjustment=0

in photoshop i can print, but this keeps happening in QTR. Im using
QTR because im using Piezography K7 inks and im not sure if ill get
the same results if i print with photoshop. its really frustrating
because each time i try it, i lose ink and its costing me. Well thank you.
