1. A liquid supply system configured to supply a liquid to a plurality of printers, the liquid supply system comprising:
a plurality of tubes configuring a supply flow path of the liquid to the plurality of printers, the plurality of tubes being connected to a tank configured to store the liquid, the tank being positioned outside the plurality of printers and provided further upstream than the plurality of printers in the supply flow path, and the liquid flowing through the plurality of tubes between the tank and the plurality of printers;
a liquid delivery mechanism being a mechanism provided in the plurality of tubes, and configured to switch between a liquid delivery state of the liquid flowing between the tank and the plurality of printers via the plurality of tubes, and a stopped state of stopping the liquid from flowing between the tank and the plurality of printers via the plurality of tubes;
a processor; and
a memory storing computer-readable instructions that, when executed by the processor, cause the processor to perform a process comprising:
circulation processing including
supply processing of supplying the liquid from the tank toward the plurality of printers via the plurality of tubes, by controlling the liquid delivery mechanism to be in the liquid delivery state, and
return processing of returning the liquid from the plurality of printers toward the tank via the plurality of tubes, by controlling the liquid delivery mechanism to be in the liquid delivery state.
