Ok, try a 'gravity purge' to prove your theory.
Increasing the height of the bottles increase the pressure in the 
lines and the inkflow.
Try printing the MIS 6 colour purge pattern, but hold the bottle rack 
6-12 inches higher than normal.
Watch out for ink spillage though, any spitting or overspray and you 
should lower the bottles.  
If you still get banding after this, I can't believe it's line 
pressure, unless you have a cart/air leak....
