| TEXT BLACK PIGMENT
BCI-3eBK ink is text black pigment used solely when printing on plain or copy paper. T Text black pigment ink is preferred for sharper text printing, has less bleed on papers, is waterproof and will not fade. Text black pigment ink is slightly slightly costlier than dye ink.
All other BCI-6 colors used in this printer are dye inks. The photoblack black ink is used when printing photos on glossy paper.
If the printer has a duplex mode or two sided printing feature, photoblack dye is used on one side and text black pigment on the other.
Because of the way an inkjet printer works, a small quantity of color ink is still used during maintenance functions even if you print mainly text.
