Abstract
Systems and methods of automatically bleeding air from a primary ink delivery system, so little or no air is mixed with the ink once it reaches a secondary ink system containing print heads. An air bleeder return assembly with a flow restrictor orifice that is configured to remove air from ink pumped to the carriage of print heads, thereby minimizing jet dropouts. Additionally, this setup provides the added advantage of the ability to run the bulk bags dry without ingesting large quantities of air to the ink delivery system.
