Abstract
PURPOSE:To effectively prevent a decrease in the ejection capability of an injection head of an ink jet recorder by applying supersonic oscillations to ink in an ink supply system under a reduced pressure to remove gases dissolved therein, whereby the entry or formation of bubbles into or at the ejection head can be prevented. CONSTITUTION:A supersonic bubble removing tank 11 is disposed between an ink supply tank 8 containing recovered ink and fresh ink and an ejection head 1. The pressure in the supersonic tank 11 is reduced by a vacuum pump 16, and supersonic enerby of 10-60kHz is supplied thereinto by a supersonic oscillator 20. As a result, gases dissolved in the ink, which cause bubbles in the ejection head 1, are turned to bubbles, which are then separated from the ink and removed from the tank 11. A regulator valve 10 serves to restrict the flow rate of ink flowing into the supersonic tank 11 to thereby keep the liquid level in the tank constant. A buffer tank 14 disposed next to a pump 13 is used to prevent pulsating motion of the liquid which is caused by the pump 13.
