Abstract: In an image-recording device, a cartridge has a first chamber and a outlet. A mount body includes a tank, first and second sensors. The tank has an inlet, and a second chamber. The liquid in the first chamber flows into the second chamber via the outlet and the inlet.

The second sensor outputs a third signal when the level is higher than a second position higher than the first position, and outputs the fourth signal when the level is lower than the second position. A controller controls a notification device to issue a notification if a condition based on the first and second signals is satisfied.

Abstract: A liquid supply apparatus includes a liquid storage container including a memory, a liquid feeding mechanism that feeds out liquid to the print head, and a second controller. A first liquid consumption amount is a consumption amount of liquid consumed in a non-printing operation in which liquid is not discharged from the print head to a recording medium, and a second liquid consumption amount is a consumption amount of liquid consumed in a printing operation in which liquid is discharged from the print head to the recording medium. The second controller calculates the second liquid consumption amount based on a liquid feeding amount of liquid fed out from the liquid feeding mechanism in a printing operation, stores the second liquid consumption amount in the memory, receives the first liquid consumption amount from the first controller, and stores the first liquid consumption amount in the memory.
