Steve,

If air is getting into a line it is more like an underpressure develops 
in that line. Could it be that for one reason or another no ink flows 
from the cart to the head?  If that head doesn't get ink it can't pull 
more ink through the line either. The more it has to print the more the 
faulty supply shows. Take out the cart. Shake it thoroughly. Make sure 
it is full. Pull some ink out the cart with a syringe. Insert the cart 
again. Pull some ink through the line with a syringe from the damper 
side. If the resistance is high it could be the cart slot blocked or 
even the line. Clean or replace the damper.
