Abstract: A liquid droplet jetting apparatus is capable of carrying out selectively a first purge mode and a second purge mode. In the first purge mode, a first air discharge purge of discharging air in an ink storage chamber is carried out while maintaining a meniscus of the ink. In the second purge mode, a second air discharge purge of discharging air inside the ink storage chamber is carried out while destroying the meniscus of the ink. Accordingly, there is provided a liquid droplet jetting apparatus in which it is possible to discharge a gas inside a liquid supply channel from an upstream side of the nozzle, and also, when the degree of thickening of the liquid inside the nozzle is extreme, it is possible to discharge the thickened liquid assuredly from the nozzle.

Abstract: An ink-jet printer performs formation of an image by jetting an ink from nozzles of an ink-jet head. When a power supply is switched ON after a time measuring section is not capable of measuring time due to the power supply has been switched OFF, then the ink-jet printer outputs to a display section a signal which causes a display control section, provided on a controller, to display a message asking a user whether or not a cleaning operation by a recovery operation control section is to be performed. Accordingly, any unnecessary operation for recovering the jetting function is reduced, solving problems such as waiting time required for performing the operation for recovering the jetting function and that the ink is consumed unnecessarily.
