ABSTRACT:
An ink-jet pen cartridge having a frame structure fabricated of a rigid plastic frame member formed of a first plastic material and an elastomeric second material. The cartridge includes an ink reservoir and an ink-jet printhead mounted to a headland region defined at the tip of a snout region of the cartridge. The ink reservoir is connected through a standpipe defined by the rigid frame material with the printhead. The second plastic material coats the inner surface of the standpipe and the headland region, to eliminate a joint at which the first and second plastic material meet in the ink path between the ink reservoir and the printhead. This eliminates a leak risk at such a joint.
