PURPOSE: An ink supply device of an inkjet printer is provided to regularly supply ink to a print head by removing pulsating or pressure changes caused by an ink pump by a damping tank, thereby improving the printing performance of a printer. CONSTITUTION: An ink supply device of an inkjet printer comprises an ink tank(10), an ink pump(30), a damping tank(40), and an air compressor(60). The ink tank stores ink supposed to supply to a printer head(50). The ink pump provides a driving force to circulate the ink of the ink tank. The damping tank temporarily stores the ink from the ink pump, thereby delivering the ink to the printer head and the ink tank. The air compressor provides compressed air to the ink tank. The ink pump presses the ink from the lower part of the ink tank, thereby delivering the ink to the damping tank. The ink from the damping tank is delivered to the ink tank through the top of the ink tank. |
