Smoother prints but no extra detail. At the Photokina I
already got the impression that Epson went for a more analogue
photo like print and I couldn't see more detail. Using more
small droplets along the range allows that. But if they are
distributed like just doubling dots it doesn't deliver more 
resolution.

Could it be that the K ink commands are now interpreted in the
printer's firmware to partition there ? If not, could a more
transparent black ink result in Clayton's observation ?  To
eliminate a third possibility: I don't think that placing is
so good that droplets fall on top of one another without any
misalignment being visible in the scans.

Or are you both looking at different B&W modes in the 3800 
driver,
c.q. drivers that are different ?
