I use "micro banding" to describe lines that cross all zones, such as
caused by a clogged nozzle.  I use "dither banding" for lines that
appear in only certain zones, as it appears to very among printer
models and seems to be related to the dither algorithms.

After looking at many prints from exchanges, it seems extremely rare
for any printer to not have any dither banding of at least a minor
sort visible only with a loupe.  I was able to reduce it to almost
zero in my old 2200 by head alignment to low line-pair numbers (#2). 
My R200 has more, I haven't tried head alignment yet, been too busy.


>- nozzle checks are perfect and alignment is good. 

You might try a low, non-optimal head alignment line-pair number just
to see what happens.

Clayton
