Abstract
A head cartridge with a bubble chamber has an ink reservoir, a print head, and an ink channel. The ink reservoir stores ink. The print head has a plurality of heaters for generating bubbles, so that ink is jetted from the print head by the bubbles. The ink channel is installed below the ink reservoir for transmitting ink into the print head from the ink reservoir, and the ink channel has a bubble chamber for collecting residual bubbles to increase an efficiency of the fluid in flowing from the ink reservoir to the ink pipe.
