I'm not getting good nozzle checks on my 2200 with the 
UltraTone carts on day three of my switch.

I got excellent nozzle checks yesterday, but this morning my 
first check showed one pattern skipping, six good. After 3 
cleanings/nozzle checks (one of them a double cleaning) I now 
have three screwed up patterns. I seem to be making it worse.  

I've never had to deal with this before. Any advice?
