If you see an error screen telling you an ink cartridge is installed incorrectly, lift up the scanner unit
and press the ink cartridge down until it clicks into place. When you're finished, press the
OK button.
If you remove a low or expended ink cartridge, you cannot re-install and use the cartridge.
Caution: If you remove an ink cartridge for later use, protect the ink supply area from dirt and dust and
store it in the same environment as the printer. The valve in the ink supply port is designed to contain
any excess ink, but do not touch the ink supply port or surrounding area. Always store ink cartridges with
the label facing up; do not store cartridges upside-down.

Replacing the Maintenance Box
If the maintenance box is full, a message appears on your product's LCD screen. Select How To > OK
and follow the steps on the LCD screen to replace the maintenance box. Make sure you have a new
maintenance box before you begin.
Note: In some print cycles a small amount of surplus ink may be collected in the maintenance box. To
prevent ink leakage from the maintenance box, the product 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 you print on and the number of
cleaning cycles that the printer performs.
Caution: Do not reuse a maintenance box that has been removed and left uninstalled for more than a
week. Keep the maintenance box away from direct sunlight.
