Ink consumption
To maintain optimum print head performance, some ink is consumed from all cartridges not only during
printing but also during maintenance operations such as ink cartridge replacement and print head cleaning.
When printing in monochrome or grayscale, color inks instead of black ink may be used depending on the
paper type or print quality settings. is is because a mixture of color inks is used to create black.
e ink in the ink cartridges supplied with your printer is partly used during initial setup. In order to produce
high quality printouts, the print head in your printer will be fully charged with ink. is one-o process
consumes a quantity of ink and therefore these cartridges may print fewer pages compared to subsequent ink
cartridges.
