Digital BW, The Print

Maybe the driver is set up differently than the 4000.  Epson seems to 
have made other changes in the driver, such as the new advanced B&W, 
and maybe they did address this??  I'd be interested in knowing.

You could print a 21 step grayscale wedge at standard color 
densities, then increase them a little and print a series to measure 
with a densitormeter or spectro.  That should confirm whether the 
total ink limit is being increased or not.
