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. This is because a mixture of color inks is used to create black.
❏ The 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. This one-off process
consumes a quantity of ink and therefore these cartridges may print fewer pages compared to subsequent ink
cartridges.

Maintenance Box Handling Precautions

Read the following instructions before replacing the maintenance box.
❏ Do not touch the green chip on the side of the maintenance box. Doing so may prevent normal operation and
printing.
❏ Do not tilt the used maintenance box until after it is sealed in the plastic bag; otherwise ink may leak.
❏ Keep the maintenance box out of direct sunlight.
❏ Do not replace the maintenance box during printing; otherwise, ink may leak.
❏ Do not reuse a maintenance box which has been removed and left detached for a long period. Ink inside the box
will have solidified and no more ink can be absorbed.
❏ Do not remove the maintenance box and its cover except when replacing the maintenance box; otherwise ink
may leak.
