Digital BW, The Print

I just installed UT7 inks in my 2200 today.  So far I can't get a good
nozzle check.  After 2 cleaning cycles the check is worse.  I made
some prints from cool to sepia to use all the inks.

It seems as if there are no mid tones at all.  Contrast is very high
and this is from a file that makes a perfect BO print.

More cleaning and nozzle checks later the checks are getting worse
like the inks in the magenta anf lt magenta postions especially aren't
spraying hardly at all.

Do you think that the inks just need to "settle", let the ink level
find inself?  For all I know they were packed and sat for days upside
down. The air holes on top are clear.  The ink monitor sees ink in all
positions.

Ideas?

Thanks
