Photo print mode can be used to obtain high level gradation print quality when using the
Photo BJ cartridge. These cartridges contain low density ink which achieves a rich
gradation and reduced graininess by printing several times over the same dot.
The printer driver divides the pixel data into a maximum of 4-values (not printed, print 1
dot, print 2 dots and print 3 dots) enabling each pixel to be printed in up to 4 gradations.
The printer therefore makes three passes using a maximum of 150% more ink than usual.
This Photo cartridge adopts drop modulation, decreasing granularity of the low density
parts by efficiently ejecting large and small ink droplets.

No head installation error
The printer cannot detect ink cartridge type, and the ink cartridges suitable for the BC-11e
and BC-12e heads are not incompatible, so that the following installation problem may
occur. Regardless if the BCI-12 Bk/Color low density photo ink cartridge is installed in the
BC-11e by mistake, the printer recognizes it as the usual BC-11e color cartridge, resulting
in low density imaging. Likewise, if the BCI-11 Bk/Color cartridge is installed in the BC-
12e head, the opposite occurs and high density image printing takes place.
