Image-recording device issuing notification concerning quantity of liquid in tank

An image-recording device comprising:

• a tank which is configured to be in connection with a liquid container;
• a head;
• a first sensor;
• a second sensor;
• a controller;
• a memory;
• and
• a notification device, the tank having an inlet, an outlet, and a chamber configured to accommodate liquid, liquid being capable of flowing into the chamber via the inlet from the liquid container, the outlet being lower than the inlet, the head being in liquid communication with the chamber via the outlet, the head being configured to eject liquid supplied from the chamber,
• wherein the first sensor is configured to output a first signal when a level of the liquid accommodated in the chamber is higher than a first position which is between the inlet and the outlet in a vertical direction whereas the first sensor is configured to output a second signal when the level of the liquid accommodated in the chamber is lower than the first position,
• wherein the second sensor is configured to output a third signal when a level of the liquid accommodated in the chamber is higher than a second position which is higher than the first position whereas the second sensor is configured to output a fourth signal when the level of the liquid accommodated in the chamber is lower than the second position,
• wherein the memory pre-stores a prescribed value indicating a volume smaller than a volume of the chamber below a position between the inlet of the tank and the outlet of the tank, and
• wherein the controller is configured to perform:
• updating a count value in accordance with ejection of liquid from the head;
• controlling the notification device to issue a notification if a first condition is satisfied, the first condition being that the count value reaches the prescribed value, the notification being either notifying that the liquid in the chamber is low or notifying that no liquid is stored in the chamber;
• and
• cancelling the notification when a user operation to replenish the liquid is performed and the first signal is received from the first sensor.

• a tank which is configured to be in connection with a liquid container;
• a first sensor;
• a second sensor;
• a controller;
• and
• a notification device, the tank having an inlet, an outlet, and a chamber configured to accommodate liquid, liquid being capable of flowing into the chamber via the inlet from the liquid container, the outlet being lower than the inlet, the liquid in the chamber being capable of flowing out of the chamber via the outlet,
• wherein the first sensor is configured to output a first signal when a level of the liquid accommodated in the chamber is higher than a first position which is between the inlet and the outlet in a vertical direction whereas the first sensor is configured to output a second signal when the level of the liquid accommodated in the chamber is lower than the first position,
• wherein the second sensor is configured to output a third signal when a level of the liquid accommodated in the chamber is higher than a second position which is higher than the first position whereas the second sensor is configured to output a fourth signal when the level of the liquid accommodated in the chamber is lower than the second position, and
• wherein the controller is configured to perform:
• controlling the notification device to issue a notification after the controller receives the fourth signal from the second sensor, the notification notifying that liquid cannot be supplied from the liquid container to the chamber;
• and
• cancelling the notification when a user operation to replenish the liquid is performed and the first signal is received from the first sensor.
