The link supplied below has a very good explanation, but you must go to page
5 and not page 1 to find it. I have an iP4000 which uses the same printhead
setup as the i860/865. What I've found is that the pigmented black from the
BCI-3eBK tank is only used in plain paper mode. It doesn't matter if it's
text or graphics, it will use the pigmented ink. In any other mode, that
tank isn't used. For all modes, the photo black or BCI-6BK is used. Use this
test to see the difference. Print a photo in grayscale or b/w. Print it once
using a setting other than plain paper. Then print it again in plain paper
mode and note how much faster it prints. If you can open the cover to view
the print you'll see the ink is applied in wide passes with the pigmented
inks and in smaller passes with the photo inks. You can also see this effect
when printing color photos and using plain paper settings. The pigmented
black will be a wide pass that's quite visible until overprinted with the
photo inks.
