What is the difference between the Canon 3 series cartridges, eg, BCI-3eC,
as used in my older S450 printer and the 6 series, eg, BCI-6C as used in my
new Pixma ip4000? They look the same physically and are interchangeable. Is
the ink inside of a different formulation? The large capacity black are
similarly slightly different codes, both 3 series and again similar in size
and shape.

Thanks,

John B.

Slightly different formulation and density between the two.
interchanging them may result in color shift in photo prints.

The BCI-6 cartridges will work in the older printer, but the BCI-3 cartridges
will show up as either constantly full, or constantly empty, depending on how
the ip4000 interprets the lack of the ink sensor prism on the bottom of the
cartridges.

Umm...the BCI-3 cartridges DO have a prism in the bottom of the ink
tanks, and they should work with the low-ink sensor just fine.

Original BCI-3 were updated and are now BCI-3e. There seem to be just as
many anonymous sources claiming that most BCI-3e is the same ink as BCI-
6 and offering as much evidence :-)
