How do I know when an ink pack needs to be replaced?

• The printer's LCD screen will display a message when one or more of the ink packs are low or expended. When ink is expended, you see the icon and the orange  Status light stays on. You may also see a message on your computer screen.

  Note: If any ink pack installed in the product is broken, incompatible with the product model, or improperly installed, Epson Status Monitor will not display an accurate ink status.
