Photo print mode can be used to obtain high level gradation print quality when using the
Photo BJ cartridge. These cartridges contain light 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 light density
parts by efficiently ejecting large and small ink droplets.

No head installation error
The printer has no detection function of the ink cartridge type, and for the BC-11e and BC-
12e, the ink cartridges to be installed are not incompatible, therefore, the following mistaken
installation may occur. In case the BCI-12 Bk/Color are installed in the print head of the BC-
11e, as the printer recognizes that the color cartridge (BC-11e) has been installed in spite of
light density photo ink cartridge installation, low density imaging is produced. In case of the
installation of the BCI-11 Bk/Color in the print head of the BC-12e, in reverse, high density
colored imaging is produced.
