Replacing an Ink Cartridge • When the red ink light flashes, one or more ink cartridges are low on ink. • When the red ink light stays on, you need to replace the cartridge(s). You’ll also see a message on your screen when you print telling you which cartridge is low. When a cartridge is more than six months old, you may need to replace it if printouts don’t look their best. If the quality doesn’t improve after cleaning and aligning the print head, you can replace the cartridge even if the red ink light is off. • Checking the Ink Supply • Purchasing Ink Cartridges • Ink Cartridge Precautions • Removing and Installing Ink Cartridges
