Abstract
There is provided an ink-jet printer including: a tank storing a pigment ink; a head; a purge mechanism; and a controller controlling the head and the purge mechanism. The controller executes: obtaining sedimentation information regarding a sedimentation amount of a pigment inside the tank, and judging whether or not the sedimentation amount of the pigment inside the tank is not less than a predetermined amount, based on the obtained sedimentation information. Further, the controller executes a first purge operation as an initial introduction purge processing for initially introducing the pigment ink from the tank to the head. Furthermore, the controller executes, as the initial introduction purge processing, a second purge processing capable of jetting, from the nozzles, the pigment ink in a larger amount than that in the first purge processing, in a case that the controller judges that the sedimentation amount is not less than the predetermined amount.
