Digital BW, The Print

I'm having a great deal of difficulty with banding on my 1280 loaded 
with UT2. 

I'm getting perfect nozzle checks, and i believe the problem might be 
improved with print head alignment. However, when i print the test 
pattern, #2 and #3 have one line and some scattered dots; #3 
doesn't even have a straight line. 

I've cleaned under the heads recently with towel/ammonia, so i think 
it's not that likeley that i have gunk there. 

Any suggestions?

thanks
matt
