INKJET PRINTER WITH BUBBLEPOINT PRESSURE REGULATOR HAVING SLOT-SHAPED BUBBLE OUTLET |
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.
