actually if you read the alotofthings url fully, which I have now, they go
one to explain why the 6BK is dye, not pigment as the Canon tables tries to
say it is. Basically the Canon table gets it wrong and another Canon
document gets it right...
However that doesn't change the fact that with my i865 I never fed more than
a dozen pages of plain paper or HR-101 through it, 99.99% of all its
printing was 6x4 photos. After printing a few hundred 6x4s the BCI-3eBK was
near empty (from brand new). So I really don't care what people try to say
about dye and pigment not mixing, and the 3eBK only being used for text etc,
you can't ignore what happens in front of your eyes.
Oh and exactly the same thing happened with my i850 before that.
