User's Guide
❏ 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 supply units 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 ink supply units may print fewer pages compared to subsequent
ink supply units.
❏ For best results, use up ink supply unit within two years of installation.

Maintenance Box Handling Precautions

Read the following instructions and Important Safety Instructions (paper manual) 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.

Replacing a Maintenance Box

In some print cycles a very small amount of surplus ink may be collected in the maintenance box. To prevent ink
leakage from the maintenance box, the printer is designed to stop printing when the absorbing capacity of the
maintenance box has reached its limit. Whether and how often this is required will vary according to the number
of pages you print, the type of material that you print and the number of cleaning cycles that the printer performs.
