摘要： An inkjet printer with a printhead and a conduit connected to the printhead. The conduit defines a flow path for the printing fluid and has an internal cross section configured such that the surface tension of printing fluid within it favors gas bubble growth along the conduit length over radial bubble growth that would fully occlude the flow path.

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; and a liquid-retaining structure in fluid communication with the regulator channel. The liquid-retaining structure is positioned and configured for capturing ink from the headspace of the ink chamber. The regulator channel is dimensioned to regulate a hydrostatic pressure of the ink supplied to the printhead.

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.
