Abstract
In an ink filling method according to the present invention, a suction arrangement having a pump is air-tightly coupled to a head unit having a plurality of ink supply ports, and sucking is performed by using the pump, thereby supplying an ink stored in an ink supply source to a plurality of the ink supply ports via a flow channel arrangement including one ink flow channel that communicates with the ink supply source and a plurality of branched flow channels that branch out from the ink flow channel and communicate with corresponding ones of the ink supply ports. The sucking is stopped from a time point when one of the branched flow channels is entirely filled with the ink until air in the flow channel arrangement moves in a branching portion, and the sucking is resumed when the air has moved in the branching portion.
