Digital BW, The Print

I'm having exactly the same problem. I had a conversation with MIS  
about this last week. Their analysis is that it's clogging, not an "air  
break" or other flow problem. Apparently, it's possible to get clogs in  
the nozzles that go into the cart, and inside the head -- not just in  
the individual jets (which could explain why sometimes a whole color  
goes missing for me sometimes). Their suggestion was to try their new  
cleaning fluid (see  
http://www.inksupply.com/index.cfm?source=html/accessory.html) on the  
parking pad, where it will wick up into the head. I've got this on  
order, and will let you know what happens.
