Abstract
An ink absorption member is inserted into a tank case and positioned to define an open space V between its bottom surface and the tank case bottom. Sequentially, then, one ink injection needle is inserted through the ink absorption member in the tank case until the tip enters the open space V. Thereafter, ink injection is begun by supplying ink through the injection needle tip. As this process proceeds, the open space V is filled with ink, the upper surface of which serves as an interface, parallel to the tank case bottom. This parallel state is maintained as the ink permeates the ink absorption member, so that the process can be uniformly completed. Further, since the open space V is filled first, the ink injection speed is not overly slow, when compared with a process during which ink is directly injected into the ink absorption member.
