摘要

PROBLEM TO BE SOLVED: To provide a gas elimination processing method or the like for preventing a gas from remaining in an ink passage. SOLUTION: An ejection pipe 152 of a container 151 filled with water is heated to generate water vapor. The water vapor is filled into the ink passage inside an inkjet head 1 via a tube 18. Then, an ink discharge face 70a is sealed by a cap so as to prevent the air from intruding into the ink passage from a nozzle formed at the ink discharge face 70a of the inkjet head 1.
