Printer, control method, and non-transitory computer-readable medium storing computer-readable instructions

A control method of a printer provided with a nozzle surface including a first nozzle and a second nozzle, and configured to discharge a first discharge liquid from the first nozzle and discharge a second discharge liquid from the second nozzle, the printer comprising:

• a first container configured to store the first discharge liquid;
• a first flow path connecting the first container to the first nozzle;
• a first valve provided in the first flow path;
• a second container configured to store the second discharge liquid;
• a second flow path connecting the second container to the second nozzle;
• a second valve provided in the second flow path;
• and
• a cap configured to form a holding space between the cap and the nozzle surface by surrounding the first nozzle and the second nozzle and contacting the nozzle surface, the cap configured to hold, in the holding space, a holding liquid, the holding liquid including at least one of the first discharge liquid, the second discharge liquid, or a cleaning liquid,
• the control method comprising:
• controlling one or both of the first valve and the second valve closed when a holding state and a non-circulating state are established, the holding state being a state in which the cap holds the holding liquid inside the holding space, the non-circulating state being a state in which neither a first circulating state nor a second circulating state is establish, the first circulating state being a state in which the first discharge liquid circulates via the first flow path, the second circulating state being a state in which the second discharge liquid circulates via the second flow path is established.

A non-transitory computer-readable medium storing computer-readable instructions that, when executed by a computer for controlling a printer, instruct the computer to perform a process, the printer provided with a nozzle surface including a first nozzle and a second nozzle, and configured to discharge a first discharge liquid from the first nozzle and discharge a second discharge liquid from the second nozzle, the printer comprising:

• a first container configured to store the first discharge liquid;
• a first flow path connecting the first container to the first nozzle;
• a first valve provided in the first flow path;
• a second container configured to store the second discharge liquid;
• a second flow path connecting the second container to the second nozzle;
• a second valve provided in the second flow path;
• and
• a cap configured to form a holding space between the cap and the nozzle surface by surrounding the first nozzle and the second nozzle and contacting the nozzle surface, the cap configured to hold, in the holding space, a holding liquid, the holding liquid including at least one of the first discharge liquid, the second discharge liquid, or a cleaning liquid,
• the process comprising:
• controlling one or both of the first valve and the second valve closed when a holding state and a non-circulating state are established, the holding state being a state in which the cap holds the holding liquid inside the holding space, the non-circulating state being a state in which neither a first circulating state nor a second circulating state is establish, the first circulating state being a state in which the first discharge liquid circulates via the first flow path, the second circulating state being a state in which the second discharge liquid circulates via the second flow path is established.
