Abstract: A maintenance device maintains a head unit including an inkjet head. The maintenance device includes a cap, a supply part, a first heating part, and a second heating part. The cap is attached on a nozzle surface of the inkjet head. The supply part stores a humidifying medium, generates a humidified air by passing air through the humidifying medium, and supplies the humidified air to the cap. The first heating part heats the supply part. The second heating part heats the cap.

Abstract: A maintenance device maintains a head unit including an inkjet head. The maintenance device includes a cap, a supply part, an air pump, and a restriction part. The cap is attached to a nozzle surface of the inkjet head. The supply part stores a humidifying medium, generates a humidified air by passing air through the humidifying medium, and supplies the humidified air to the cap. The air pump sends air recovered from the cap to the supply part through a supply flow pass. The restriction part is provided in the supply flow pass, and generates a loss of pressure of 4σ/R or more (σ: a surface tension of the humidifying medium WM, R: an inner diameter of the supply flow pass).

Abstract: A maintenance device a maintains a head unit including inkjet heads. The maintenance device includes a plurality of caps, an air supply port and an air discharge port, one recovery part, and a plurality of air supply parts. The caps are provided for the inkjet heads, and attached on nozzle surfaces of the inkjet heads. The air supply port and the air discharge port are provided for the cap. The recovery part recovers air through the air discharge ports of all the caps. The supply parts are provided for the caps, and supply a humidified air generated by humidifying the air recovered by the recovery part, to the air supply ports. The supply parts are arranged around the recovery part. In the cap, the air discharge port is provided on a side of the recovery part, and the air supply port is provided on a side of the supply part.

Abstract: A maintenance device includes a cap, an air supply port, an air discharge port, and a suppression member. The cap covers a nozzle surface of an inkjet head. The air supply port and the air discharge port are provided in the cap. The suppression member is provided between the nozzle surface and the air supply port, and has a first gap from the air supply port and a second gap from the nozzle surface. The suppression member has a plurality of through-holes penetrating from a side of the air supply port to a side of the air discharge port at a position not facing the air supply port. The through-holes have the same diameter. The closer the through-holes are to the air discharge port, the higher a density of the through-holes is.
