ABSTRACT:
An ink jet system printer of the ink-on-demand type includes an ink liquid reservoir for supplying ink liquid to a printer head by means of the capillarity. An ink cartridge is removably mounted on the ink liquid reservoir in order to maintain the ink liquid level in the ink liquid reservoir at a desired level. An opening is formed in the ceiling wall of the ink liquid reservoir for ensuring smooth ink supply from the ink liquid reservoir to the printer head. A porous capping member is disposed in the opening to minimize the evaporation of the ink liquid. A thin gap is formed in the porous capping member so that the air disposed in the ink liquid reservoir communicates to the ambience.
