There is provided a liquid droplet jetting apparatus, including: a liquid droplet jetting head in which a plurality of nozzles and a plurality of individual channels are formed; a purge mechanism; a judgment mechanism which judges whether or not a defective nozzle in which a jetting failure occurs is included in purge target nozzles; a heating mechanism which heats a liquid in the plurality of individual channels; and a controller which controls the purge mechanism and the heating mechanism. In a case that the judgment mechanism judges that the defective nozzle is included in the purge target nozzles, the controller controls the heating mechanism and the purge mechanism to heat the liquid in a part of the plurality of individual channels, which include an individual channel communicating with the defective nozzle, and to execute the purge operation for the purge target nozzles.

There is provided a liquid jetting apparatus including: a liquid jetting head including a pressure generating element and a plurality of nozzles arranged in rows in a nozzle-row direction; and a controller. The controller is configured to: determine a basic flushing amount for each nozzle; make the liquid jetting head carry out flushing with the basic flushing amount for inner-side nozzles positioned at an inner side in the nozzle-row direction; and make the liquid jetting head carry out flushing with a flushing amount larger than the basic flushing amount, for outer-side nozzles positioned at an outer side in the nozzle-row direction, of the inner-side nozzles.

A liquid jetting apparatus includes: a head unit including a liquid jetting head, a regulating member arranged to sandwich the head unit from a nozzle array direction, a restriction mechanism configured to restrict the head unit from displacement in an orthogonal direction perpendicular to the nozzle array direction, and a landing position correction mechanism configured to correct position of landing the liquid jetted from the plurality of nozzles onto the medium in the orthogonal direction. The restriction mechanism restricts a portion of the head unit inside of outmost nozzle arrays in the orthogonal direction.

A liquid jetting apparatus includes: a plurality of liquid jet heads each of which has a nozzle surface in which a plurality of nozzles are formed to align in one direction, a retention member which retains the plurality of liquid jet heads in a state of being arranged along one plane, a transport mechanism which transports a medium in a transport direction along the one plane, and a displacement mechanism which displaces the retention member in a specified direction toward one side along a direction intersecting the nozzle surfaces by curving the retention member or rotating the same in a rotation direction when the retention member extends due to temperature change on the one plane in an intersectant direction intersecting the transport direction.

An apparatus for ejecting droplets is provided with a ejecting head for discharging droplets, an electric circuit board having an electric circuit formed on a surface of the electric circuit board, the electric circuit being connected to the ejecting head, a holder for supporting the ejecting head and the electric circuit board, and a cover that overlaps the surface of the electric circuit board when the cover is fixed to the holder. The apparatus for ejecting droplets is further provided with a seal member that fills a gap formed between a peripheral region of the surface of the electric circuit board and an inner surface of the cover. The seal member effectively prevents droplets mist from penetrating to the electric circuit.
