In an ink supply system, a main ink tank and an ink head are connected together via a main supply channel. A sub-ink tank is connected to the main supply channel via a sub-supply channel. An upstream-side valve is provided on an upstream-side portion of the main supply channel. During standby, a first standby setting processor of a controller sets a first standby state in which a first upstream-side valve is open, and a second standby setting processor sets a second standby state in which the first upstream-side valve is closed. A standby state determination processor determines whether or not the amount of time elapsed from when a setting operation was done by the first standby setting processor or the second standby setting processor is greater than or equal to a first amount of time. The standby state switching processor switches between the first standby state and the second standby state when it is determined that the elapsed time is greater than or equal to the first amount of time.
