Digital BW, The Print

Thansk so much for all the replies.  What has me confused is that I 
have been able to get to the point that I get a clean nozzle check 
with both OEM and UT2 after lots of work.   As soon as I print a 
purge print, I get banding and the nozzle check is bad again.  It is 
on multiple heads.  The main heads I am having trouble with are the 
yellow, light cyan and light magenta.  It varies from a few nozzles 
to complete shut down of the heads.  Thanks for any suggestions.  
Will contact MIS.
