Abstract: A liquid discharging device includes: a cartridge mounting part configured to have a cartridge retaining a liquid mounted thereon; a head connected to the cartridge mounting part and configured to eject the liquid from a nozzle which is an opening provided on the nozzle surface of the head; and a discharge unit including a cap configured to cover the nozzle surface, the discharge unit being configured to discharge the liquid from the nozzle by creating a negative pressure in an internal space of the cap. The liquid is at least an ink, a storage liquid or a mixture thereof. The cartridge includes a first cartridge for retaining the ink and a second cartridge for retaining the storage liquid The ink includes a pigment, a resin microparticle, an organic solvent, a surfactant, and water. The storage liquid includes a water-soluble polymer, an organic solvent, a surfactant, and water.

Abstract: A liquid discharging device includes a head, a cap, a first wiper, a discharge channel, and a controller. The head ejects liquid from a nozzle. The cap is configured to abut against a nozzle surface at a covered position and to separate from the nozzle surface in a retracted position. The first wiper wipes the nozzle surface. The discharge channel connects an internal space of the cap to an outside of the cap. The controller executes a first maintenance process and a second maintenance process. In the first maintenance process, a first maintenance liquid contacts the cap in the retracted position and the first wiper. In the second maintenance process, a second maintenance liquid different from the first maintenance liquid is distributed to the internal space of the cap and the discharge channel.

Abstract: A liquid discharging device includes: a cartridge mounting part; a tank connected to the cartridge mounting part; a head that ejects a liquid; a discharge configured to discharge the liquid from the head; and a controller. The liquid is at least a storage liquid, a first liquid which is different from the storage liquid, or a mixture thereof. In a storage mode, the controller executes: a return process of returning the first liquid from the tank to a first liquid cartridge mounted on the cartridge mounting part; a first discharging process of discharging the first liquid from the head; a storage liquid supplying process for supplying a storage liquid from a storage liquid cartridge to the tank; and a second discharging process of discharging the storage liquid from the head, after executing the storage liquid supplying process.
