<p>PROBLEM TO BE SOLVED: To provide a liquid discharge device which can discharge an inside liquid from a nozzle even though it is not used for a long period and reduce the consumption of the liquid at the initial use as much as possible.SOLUTION: At the time of storing a printer having an ink channel from a cartridge holder 6 to a head inner channel 19 in an ink jet head 5 through an ink supply tube 17 and an ink supply channel in a sub-tank 4, an ink I is charged into the ink supply tube 17 and a channel part on the upper stream side than a middle part of a damper chamber 24 in the ink supply channel, and a preservation liquid H is charged into a channel part on the lower stream side than the middle part of the damper chamber 24 in the ink supply channel and the head inner channel 19. The preservation liquid H has viscosity lower than that of the ink I or volatility lower than that of the ink I.</p> |
