Liquid consumption apparatus

A liquid consumption apparatus comprising:

• one or more mount case on which a plurality of cartridges is mounted, each of the plurality of cartridges having a first liquid chamber;
• a plurality of tanks each having a second liquid chamber;
• a plurality of liquid channels, each of the plurality of liquid channels having one end in communication with the second liquid chamber of one of the plurality of the tanks and another end in communication with the first liquid chamber of a corresponding one of the plurality of cartridges mounted on the one or more mount case;
• a head having nozzles in communication with the second liquid chamber, the head being configured to eject liquid from the nozzles;
• a display;
• and
• a controller configured to:
• determine, for each of the plurality of cartridges, whether a remaining amount of liquid in the first liquid chamber is smaller than a first liquid amount;
• in response to determining that a first cartridge exists in the plurality of cartridges, determine, for each cartridge other than the first cartridge among the plurality of cartridges, whether a remaining amount of liquid in the first liquid chamber is smaller than a second liquid amount, the first cartridge being a cartridge for which it is determined that the remaining amount is smaller than the first liquid amount, the second liquid amount being larger than the first liquid amount;
• in response to determining that a second cartridge exists in the plurality of cartridges, determine whether a remaining amount of liquid in the first liquid chamber of the second cartridge is smaller than the first liquid amount, the second cartridge being a cartridge for which it is determined that the remaining amount is smaller than the second liquid amount;
• and
• in response to determining that a particular second cartridge exists, control the display to display a first screen including a first object that prompts replacement of the first cartridge and the particular second cartridge, the particular second cartridge being the second cartridge for which it is determined that the remaining amount is smaller than the first liquid amount.
