Abstract
In an image-recording device, a cartridge has a first chamber, an outlet, and a first air communication portion for air-communication between the first chamber and the atmosphere. A mount body includes a tank, and first and second sensors. The tank has an inlet, a second chamber, and a second air communication portion for air-communication between the second chamber and the atmosphere. Liquid in the first chamber flows into the second chamber. The first sensor outputs a first signal when a level of the liquid in the second chamber is higher than a first position, and outputs a second signal when the level is lower than the first position. The second sensor outputs a third signal when the level is higher than a second position which is higher than both the first position and the inlet, and outputs a fourth signal when the level is lower than the second position.
