Abstract:
1. A method of printing comprising: providing a carriage with an ink container and a ejector die mounted thereon, the ink container including a vent hole for removing air from the ink container; printing on a medium including reciprocatably moving the carriage back and forth over the medium and selectively ejecting ink from the ejector die onto the medium using ink supplied to the ejector die from the ink container; and extracting air from the ink container including trapping air between an inside wall of the ink container, a front face of a mass within the ink container, and the vent hole, including forcing air through the vent hole by moving the mass within the ink container toward the vent hole, wherein said movement of the mass toward the vent hole is generated by momentum forces arising in the mass from the back and forth movement of the carriage.
