If a cartridge is expended, you must replace it to be able to print. If a cartridge is low, you can continue printing until a cartridge needs replacement.Note:
You cannot print when an ink cartridge is expended even if the other cartridges are not expended. Replace any expended cartridges before printing.When an installed ink cartridge is more than six months old, you may need to replace it if your printouts do not look their best, even after cleaning and aligning the print head.
