<P>PROBLEM TO BE SOLVED: To provide a liquid droplet ejection device capable of excellently dispersing liquid in an ink supply tube in such a state that components such as pigments are kept uniform. <P>SOLUTION: The liquid droplet ejection device includes: a liquid storage part for storing the liquid containing components that may settle out; a liquid supply tube for supplying the liquid; a container connected to the liquid supply tube; an ejection head connected to the container and ejecting the liquid to a medium to be ejected; a stirring means for stirring the liquid in the container; and an input means in which a predetermined instruction is input. The liquid droplet ejection device is provided with: a control means for controlling first operation that the liquid is ejected from the ejection head, second operation that the liquid is stirred in the container, and third operation that the liquid is ejected to the medium to be ejected; a first time-measuring means for measuring first elapsed time t1 that is the time until the predetermined instruction is input after finishing the operation that is selected from the first operation, stirring operation performed after replacement operation, and printing operation; and a second time-measuring means for measuring second elapsed time t2 that is the time until the predetermined instruction is input after finishing the performance of the second operation in the container. <P>COPYRIGHT: (C)2012,JPO&INPIT |
