A four color ink cartridge device for use in, for example, highlight or process color ink jet printing operations is disclosed. As shown in the Figure, the device is comprised of manifolds 1 and 2 for transferring liquid inks residing in reservoirs 3 and 9, respectively. Reservoir 3 houses cavities 4 and 5, and similarly for reservoir 9 (cavities not shown), thereby providing four separate cavities or chambers for up to four different liquid ink formulations. A flexible printed wire board mounted on edge card 6 serves as a connector and heat sink, respectively, for thermal ink jet die heads 7. Separate channels 8 appropriately etched or machined in both manifolds serves to convey ink from the respective reservoirs to the respective die heads. The device is useful in, for example, carriage type mechanisms. The device reduces the total number of parts and gangs the die heads into a square geometry that is well suited for capping and maintenance station simplicity and economy.
