I thought I read that the Black tank is not used in printing photos
but I can not seem to find the post.

Would someone please confirm that information. If that is the case I
will keep my black compats if they will not be interacting with colors

Hmmm. judging by my black tank, I would have to say it is used in
photos. Ive printed 95 percent photos and the black is half used.
I would still appreciate some input.

thanks

Black ink is used - I watched it print out a photo with the cover open
(you have to hold down the little square button). It laid down a layer
of black before colors started appearing. The use of black is important
in printing photos, otherwise you get a "black" that is not a true
black, but a mixture of the three colors.

I should have added that it only lays down the black if it is REQUIRED
in the photo, if there is something black or very dark in it.

The i850 uses black in photos. Gray scale up to about 80% is
printed using equal amounts of c y m ink, above 80% it uses
only black. You can verify that by printing a uniformly graduated
gray scale and looking at it through a microscope.

Thank you very much. Very informative. I noticed that the second
alignment option where it prints only the black "L" and "M" columns,
it uses mixed ink. I could tell because it came out green tinted and
not pure black as the black only cartridge would produce.

Im in the process of returning color ink. Magenta was way off as well
as cyan. yellow was pretty close not still a shade off.
