    摘要： A method of regulating a hydrostatic pressure of ink supplied to an inkjet printhead is provided. The method comprises withdrawing a volume of ink from an ink chamber and simultaneously bubbling air bubbles into the chamber via a bubble outlet to balance the withdrawn volume of ink. Each air bubble is defined by an air cavity trapped inside a film or a body of ink. The bubble outlet is dimensioned to control a Laplace pressure of the air bubbles, thereby regulating a hydrostatic pressure of the ink.

    摘要翻译： 提供一种调节供应给喷墨打印头的墨水静压力的方法。 该方法包括从油墨室中取出一定体积的油墨，同时通过气泡出口鼓泡气体进入室内以平衡抽出的油墨体积。 每个气泡由被捕获在膜或油墨体内的空气腔限定。 气泡出口的尺寸被设计成控制气泡的拉普拉斯压力，从而调节油墨的静水压力。

    摘要： A inkjet printer that has an ink supply (112), a printhead integrated circuit (IC) (74) in fluid communication with the ink supply via an upstream ink line (67), the printhead IC (74), a waste ink outlet in fluid communication with the printhead IC (74) via a downstream ink line (106), an upstream shut off valve (138) in the upstream ink line (67), and, a downstream pump mechanism (114) in the downstream ink line. With a valve upstream of the printhead and a pump downstream of the printhead, the user has active control of the ink flow upstream, downstream or in the printhead IC. In the event that problems such as ink flooding, color mixing or printhead depriming occur, the user can follow simple troubleshooting protocols to rectify the situation.

    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 for bubbling air bubbles into the chamber, each air bubble comprising an air cavity trapped inside a film or a body of ink; 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 the chamber as result of supplying ink to the printhead, thereby regulating a hydrostatic pressure of the ink.

    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; a regulator channel having a first end communicating with the air inlet and a second end communicating with a headspace of the chamber, the second end defining a bubble outlet; and a wetting system for maintaining at least some liquid in the regulator channel, thereby ensuring that air entering the headspace first passes through the liquid. The wetting system comprises a first wetting chamber connected to the first end, a second wetting chamber connected to the second end, and a liquid-retaining structure positioned in the second wetting chamber. The regulator channel, the first wetting chamber, the second wetting chamber and the liquid-retaining structure are all in fluid communication with each other. The regulator channel is dimensioned to control a Laplace pressure of air bubbles drawn from the bubble outlet as result of supplying ink to the printhead, thereby regulating a hydrostatic pressure of the ink.
