Are you saying this is true on all color photo printers or just the IP300?
The reason I ask, is that my Pixma 6600D has a black ink cartridge and it
does go down when printing photos. In fact, color photos is the only
thing ever printed on that printer. That black went someplace.
Edwin - the IP3000, ip4000, and ip5000 had a bci-3eBK pigment based ink cart
that is larger than the bcdi-6 black dye-based cart. The BCI -3eBK cart was
only used when the printer is set to plain paper and is strictly for text
printing. The ip3000 printer had cyan, magenta, and yellow bci-6 carts and
had to make black with a combination of these inks when printing photos.
The ip4000 and ip5000 had the pigment based ink cart, bci-3eBK for text
printing when set to plain paper and also had a bci-6 black dye-based cart,
together with a cyan, magenta, and yellow, for photo printing. Your ip6600
is a six color printer that includes black, cyan, magenta,yellow, photo
magenta, and photo cyan, all designed for photo printing. It still does a
creditable job on text printing with its dye-based inks. You will use black
ink where necessary for photo printing on your printer, but the six color
printers, when printing photos, will usually go through two or three times
as many photo cyan and photo magenta carts as cyan, magenta, and black, and
yellow use will fall somewhere in between.
