Digital BW, The Print

Hi!!!  I just hooked up my new MIS Continous Feed System.  I'm 
psyched!  Anywho, all's looking great, my first print is 
BEAUTIFUL... but, after I hooked up the bottles, the tubes really 
lost a lot of ink, there is a LOT of air, particularly in the PC 
position.  Will this eventually fix itself?  It looks like as much 
as ten to eleven inches of "open space" in some of these tubes.  
They were totally full when I installed the inks and this air didn't 
really get so huge until after I started running the tests.

Thanks for any input.
