Abstract
An ink cartridge for use in a thermal ink jet printer has a printhead with an edgeshooter configuration and improved heat management. The cartridge has a supply of ink in a chamber and a passageway for placing the chamber in fluid communication with the printhead. The printhead has an array of heating elements, one in each of a plurality of ink channels, and located a predetermined distance from the channel opens which serve as nozzles. The passageway directs the ink in a path closely adjacent the heating elements, so that more of the waste heat generated by the heating elements are transferred to the ink prior to entry of the ink into the channels, thereby resulting in more waste heat being carried away by the ejected ink droplets.
