Abstract
An ink cartridge storage structure and method provide consistent print density and quality by mixing the ink when the cartridge is removed from the packaging and installed to a printer for use. An ink-filled ink cartridge with an ink supply port installable to the head of a printer is stored inside an individual box made to hold the ink cartridge. The ink cartridge is stored inside the individual box so that the ink supply port is at the top when the box is in the normal upright position.
