What are the ink cartridge error messages and what do they mean?

The front panel can display the following ink cartridge error messages: Cartridge Missing (cartridge is not inserted), Faulty Cartridge (cartridge has expired or is defective), Cartridge Nearly Reached End of Life (cartridge is low), and Cartridge Empty (cartridge has no ink remaining). If a cartridge has passed its expiration date, it will be shown as faulty and must be replaced. (Page 59)
