Quick work! I hope MIS is just as quick to produce, I can think of a 
couple people awaiting anxiously....

When I first ran my 7500 I had GEN 4 K in it, and it seemed that 
made the problem worse, at least for me. Of course that ink probably 
has a lot more dye in it that the "all pigment" blacks???

This one gets my vote, I think the machine is just set up to spit 
out more black ink to make up for the whimpy D-max of the Arc-K.

I would be curious to compare dot-size & graininess, would you 
consider exchanging a print / grayscale?

Also: For those who where curious I have an amusing horror story to 
report on my efforts to install and learn Linux so I could try Gimp-
print. The short version is; I installed SuSE which seemed to have 
the lates version of everything, couldn't even get my printers to 
work. Formatted the drive, installed Red Hat, could get my printers 
to work. Went back to Suse, still no go. And all this time, mind 
you, damn near nothing else worked either: no modem. no audio, 
rudimentary scanning, Suse wouldn't drive my monitor properly, in 
short, a mess. And then the fun began: I decided to scothch the 
whole thing, but discovered that I couldn't get rid of the Linux 
bootloader. Before I figured out how, I tried 3 'repair 
installations' of Win XP, and the only thing that got 'repaired' was 
my internet connection, I no longer have one, and don't have the 
option of setting up a new one. I am now online through a second 
installation of Win XP on the drive that I had Linux. Bah-humbug!

One note however; for anyone using Linux already, who maybe hasn't 
updated recenlty: The Gimp-print driver that Roy is using is 4.3.4; 
That's still very developmental; the one before that 4.3.3, is 
included in SuSE and other places, and already supports quadtone B&W 
printing. The release notes state that it hasn't been tweaked for 
any particular ink/paper sets, so it would still require some fine-
tuning, but it might be worth checking out for those inclined to 
experiment
