Digital BW, The Print

Hi All....

I'm feeling incredibly frustrated with the micro-banding in the midtones on my 2200. I've 
done the nozzle checks/head alignments and even tried lowering the number, as Clayton 
suggested - all to no avail. The prints just look terrible, with both vertical and horizontal 
banding in any large expanse of mid-gray, but nowhere else. The horizontal lines show up 
as three lines quite close together, some space, then three more lines, on down the print, 
with the verticals appearing a bit thicker and evenly spaced.

What the h*** am I missing (printing BO, btw)?? I've looked at past posts about this and 
don't see anything I haven't tried. Is this a 2200 issue that is improved on other models 
like the 4000? Is it my image? 

And....has anyone definitively determined that the 3800 prints true BO?

Thanks!
Sarah
