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

• When an ink cartridge is expended, the icon is displayed on the printer's LCD screen.

  You may also see a message on your computer screen.

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

  You may also need to replace a cartridge that is more than six months old if your printouts do not look their best, even after cleaning and aligning the print head.
