Important:

Once a maintenance box has been installed in a printer it cannot be used with other printers.

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 replace the maintenance box during printing; otherwise, ink may leak.
❏ Do not remove the maintenance box and its cover except when replacing the maintenance box; 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.
❏ Keep the maintenance box out of direct sunlight.
❏ Do not store the maintenance box in high or freezing temperatures.

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.
When a message is displayed prompting you to replace the maintenance box, refer to the animations displayed on
the control panel. The need for replacement of the box does not mean that your printer has ceased to operate in
