摘要： An inkjet printer that has a printhead for printing onto a media substrate, and a reservoir for containing a quantity of ink, the reservoir having a lower portion for holding ink and an upper portion defining a headspace of air above the ink. A fluid connection extends between the printhead and the reservoir. A pump draws air from the headspace to lower its air pressure and thereby controls the hydrostatic pressure of the ink at the printhead.
摘要翻译：一种喷墨打印机，其具有用于打印到介质基板上的打印头和用于容纳一定量的墨水的储存器，该储存器具有用于保持墨水的下部和在墨水上方限定空气顶部空间的上部。流体连接在打印头和储存器之间延伸。泵从顶部空间抽吸空气以降低其空气压力，从而控制打印头处的墨水的静水压力。

摘要： There is provided an ink pressure regulator for regulating a hydrostatic pressure of ink supplied to an inkjet printhead. The regulator comprises: an ink chamber having an ink outlet for fluid communication with the printhead via an ink line; an air inlet open to atmosphere; a bubble outlet positioned for bubbling air bubbles into a headspace of the chamber, each air bubble comprising an air cavity trapped inside a film of ink; a capillary channel in fluid communication with ink contained in the ink chamber, said capillary channel supplying ink from the chamber to the bubble outlet by capillary action; and an air channel connecting the air inlet and the bubble outlet. The bubble outlet is dimensioned to control a Laplace pressure of air bubbles drawn into said chamber as result of supplying ink to the printhead, thereby regulating a hydrostatic pressure of the ink.

摘要： An inkjet printer has an inkjet printhead and an ink pressure regulator for regulating a hydrostatic pressure of ink supplied to the printhead. The regulator includes a bubble outlet positioned in a headspace of an ink chamber for bubbling air bubbles directly into the headspace at all operative ink levels. A capillary channel supplies ink from the chamber to the bubble outlet by capillary action and an air channel connects an air inlet with the bubble outlet. The bubble outlet is dimensioned to control a Laplace pressure of air bubbles drawn into the ink chamber as result of supplying ink to the printhead, thereby regulating a hydrostatic pressure of the ink.
