Abstract

Disclosure is an ink supply system for an ink-jet head with a steam cleaning function. The ink supply system includes an ink-jet head including a nozzle, an ink storing device, a gas pressure control system applying negative or positive pressure to the ink storing device, a cleansing solution storing part, and a steam generating device changing at least a part of the cleansing solution into steam, wherein the cleansing solution or the cleansing solution steam is inserted into the ink storing device to clean the ink storing device and the ink-jet head. The ink supply system cleans quickly and completely residue of ink to prevent contamination during the process of changing and using ink, and the ink storage, the ink-jet head, and the ink flow path are cleaned by evaporated cleansing solution during long-term printing, thereby maintaining the ink-jet head and the ink supply system into the initial state.
