ABSTRACT:
The present invention provides an outer cover to secure a printhead-ink cartridge and can be used in a segregated printhead-ink cartridge which is modified from an all-in-one printhead-ink cartridge. The inner and outer mounting and matching dimensions of the outer cover fit the outer frame edge (2) of the printhead and the printhead rack. The outer cover is an integrated cartridge holder comprising functional parts including locking tabs (4a,4b), at least one outer cover operating handle (3), at least one printhead locking tab (7), at least one printhead operating handle (5), and at least one pressing rib (6). The outer cover ensures that the ink cartridge (8) is securely mounted in the frame of printhead (1) and that the printhead is accurately positioned in the printhead rack. When the ink is depleted only the ink cartridge inside the printhead needs to be replaced.
