QTR-Quadtone RIP

I've been able to eliminate the pizza wheel tracks by sticking a  
sheet of fairly heavy paper in the 2200 through the rear feed slot  
with the paper clamp (or whatever it is called) set loose and pulling  
the paper quickly back and forth while blasting the offending wheel  
with compressed air from a can.  Maybe the air blows out the dirt or  
there may be some lubricant mixed in with it. So far it has worked.   
When it doesn't I'll probably get a new machine.
