Abstract
An ink cartridge carrier for an ink cartridge of an ink jet printing device is resiliently mounted to the ink cartridge carrier to minimize the size of the ink cartridge carrier. The reduction in size is accomplished by mounting the latching mechanism to the ink cartridge carriage with an expansion spring positioned in a spring opening in both the latching mechanism and the ink cartridge carrier. Only a latching lip of the latching member extends above the ink cartridge carrier so as to engage an upper surface of the ink cartridge.
