Liquid supply apparatus, liquid discharge apparatus, and liquid supply method
A liquid supply apparatus comprises: a liquid supply unit to perform an operation to supply liquid from a main tank to a sub tank; a liquid surface detection unit configured to detect a liquid surface of the liquid stored in the sub tank; and a control unit configured to control the liquid supply unit to execute first liquid supply operation to control the liquid supply unit to supply liquid to the sub tank until the liquid surface is detected by the liquid surface detection unit and a second liquid supply operation to supply liquid to the sub tank after the liquid surface is detected by the liquid surface detection unit. The control unit controls, based on at least one of a liquid supply amount and a liquid supply time in the first liquid supply operation, the time during which the second liquid supply operation is executed.
