摘要： An inkjet printer includes a printhead for printing onto a media substrate, the printhead defining a plurality of nozzles from which ink is expelled; an ink tank provided upstream of the printhead; a sump provided downstream of the printhead for collecting unused ink from the printhead, the sump having a lower portion for holding the unused ink and an upper portion defining a headspace of air above the unused ink; a first fluid conduit extending between the printhead and the sump for communicating the unused ink from the printhead to the sump, the first fluid conduit connecting the sump to a position in the printhead upstream of the plurality of nozzles; and a pump connected to the sump, the pump for drawing air from the headspace of the sump into atmosphere and effecting a negative pressure in the printhead upstream of the nozzles. Communication of ink from the ink tank to the printhead is effected by the negative pressure generated by the drawing of air from the headspace of the sump.

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.

摘要： An ink pressure regulator for regulating a hydrostatic pressure of ink supplied to an inkjet printhead. The regulator includes an ink chamber having an ink outlet for fluid communication with the printhead via an ink line. A roof of the ink chamber includes: 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 liquid in the regulator channel, thereby ensuring that air entering the headspace first passes through the liquid. 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.

摘要： An ink cartridge suitable for regulating a hydrostatic pressure of ink supplied to an inkjet printhead is provided. The cartridge 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： An inkjet printer includes an inkjet printhead and an ink pressure regulator connected to the printhead via an ink line. The ink pressure regulator includes: an ink chamber having an ink outlet connected to the ink line; an air inlet open to atmosphere; and an air channel connected to the air inlet. The air channel has a constriction defining a bubble outlet, with the bubble outlet being configured as a slot positioned for bubbling air into ink contained in the chamber. A width dimension of the slot is dimensioned to control a Laplace pressure of air bubbles drawn into the ink as result of supplying ink to the printhead, and thereby regulates a hydrostatic pressure of the ink.

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.
