Abstract: A liquid ejecting head unit includes head main bodies capable of ejecting liquid droplets from nozzle openings by applying pressure to liquid inside pressure generating chambers communicated with the nozzle openings. Liquid flow paths that are formed for the head main bodies connect the nozzle openings including the pressure generating chambers and storage members that store liquid to be supplied to the pressure generating chambers. Heating members are disposed in the vicinity of the liquid flow paths and heat the liquid flowing through the liquid flow paths. A control unit controls the heating members. Temperature detecting units detect temperatures of the liquid flowing through the liquid flow paths. The control unit controls the heating members based on the temperatures of the liquid, which are detected by the temperature detecting units and lengths of the liquid flow paths extending from the storage members to the head main bodies.

Abstract: The invention provides a liquid ejecting unit and a liquid ejecting apparatus that can prevent the film of the damper flow passage member from wrinkling. In a surface of a damper flow passage member covered with a film, a communication passage, a first filter chamber in which a first filter is disposed, and an empty chamber disposed between a pressure chamber and the communication passage are provided. The film is attached to a surface of each of the pressure chamber, the empty chamber, and the communication passage so as to cover a first flow passage and a second flow passage with the empty chamber therebetween. In a region of the film facing the empty chamber, a weak portion is formed that permits the stretching of the film.

Abstract: A liquid ejecting head that ejects a liquid from a nozzle opening includes a first channel-forming substrate having a pressure-generating chamber that includes a diaphragm. A second channel-forming substrate is disposed on a surface opposite the diaphragm. An actuator that includes the diaphragm applies pressure to the pressure-generating chamber to eject the liquid from the nozzle opening.
