Choosing the Best Cartridge
Canon offers several BJ print cartridges and ink tanks for use in the
C3000. (BJ print cartridges contain the BJ print head and ink, while BJ
ink tanks contain only ink.) Use the following descriptions to decide
which type of cartridge best suits your particular needs.
N
To avoid printing problems, use only the BC-21 BJ cartridge for normal
printing (or the separately sold BC-20 Black BJ cartridge, if you rarely
print color). The BC-22 Photo Color BJ Cartridge (sold separately) is for
printing photo-realistic color images. Other cartridges can produce
unsatisfactory results. In addition, use only BCI-21 Black and BCI-21
Color ink tanks in the BC-21 Color BJ cartridge.
BC-21 Color BJ Cartridge
The BC-21 incorporates a BJ print head and
two replaceable ink tanks (a BCI-21 Black
and a BCI-21 Color). Use this cartridge for
normal printing.
BCI-21 Black ink tank 
Purchase this ink tank from your local
Canon dealer as the black ink runs out of the
BC-21 Color BJ cartridge.
BCI-21 Color ink tank
Purchase this ink tank from your local
Canon dealer as the color ink runs out of the
BC-21 Color BJ cartridge.
BC-20 Black BJ Cartridge
This cartridge incorporates a BJ print head
and black ink in a single unit. The BC-20 can
be used if most of your printing is black, e.g.
for receiving faxes, making copies, and
monochrome printing. It can print twice as
fast as a color cartridge, and at higher
resolution.
