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

• When a cartridge 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 of the cartridges installed in the product are 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.
