THERMALLY DRIVEN TYPE INKJET PRINTHEAD

摘要

A thermally driven type ink-jet print head is provided to install bubble separation walls for guiding a disappearing position of bubbles on a heater to remove the bubbles on the bubble separation walls. A thermally driven type ink-jet print head includes heaters(113), a conductive line(114), and bubble separation walls(151). The heaters heat ink in an ink chamber to generate bubbles. The conductive line applies a current to the heaters. The bubble separation walls project on the heaters to protect the heaters by guiding a disappearing position of the bubbles when the bubbles are shrunk and disappeared. The bubbles are disappeared on the bubble separation walls.
