System and method for removing air from an inkjet cartridge and an ink supply line

摘要

A printing system includes an inkjet cartridge, an ink reservoir, and a reversible pump. A method and system of operating the printing system are providing in which first fluid line couples the ink reservoir and an input port of the inkjet cartridge. A second fluid line couples the reversible pump and an output port of the inkjet cartridge. The reversible pump is operated in a first direction to supply ink from the ink reservoir to the ink jet cartridge via the first fluid line. The reversible pump is a second direction to supply ink from the ink reservoir to the inkjet cartridge via the second fluid line. The reversible pump is operated in the first direction and the second direction repeatedly and sequentially for a predetermined duration.

1. A printing system, comprising:
an inkjet cartridge; an ink reservoir; a reversible pump; a first fluid line that couples the ink reservoir and an input port of the inkjet cartridge; a second fluid line that couples the reversible pump and an output port of the inkjet cartridge; a supply of a gas coupled to the ink reservoir; and a controller that repeatedly operates the reversible pump sequentially in a first direction and a second direction, wherein operating the reversible pump in the first direction supplies ink from the ink reservoir to the inkjet cartridge via the first fluid line and operating the reversible pump in the second direction supplies ink from the ink reservoir to the inkjet cartridge via the second fluid line; and wherein the controller causes gas from the supply of the gas to be introduced into the ink reservoir and thereby causes ink to be released through a nozzle of the inkjet cartridge.
