PROBLEM TO BE SOLVED: To provide a maintenance method for a liquid ejection device capable of suppressing liquid from being solidified in a liquid supply flow path while suppressing a foreign matter from adhering to the liquid supply part.SOLUTION: A maintenance method for a liquid ejection device includes: a supply needle 28 that is inserted into an ink cartridge so as to guide ink when the ink cartridge is mounted to a cartridge holding part 14; an alternative mounting body 60 that can cover ink while a guide hole 62 for the ink from the ink cartridge in the supply needle 28 is being exposed to air; and an ink supply tube where an ink flow path for supplying the ink guided via the supply needle to a nozzle of liquid ejection head is formed. The maintenance method has a covering step of covering the supply needle 28 by the alternative mounting body 60, and a discharge step of discharging the ink from the ink flow path communicated with the supply needle 28 covered by the alternative mounting body 60 in the covering step. |
