LIQUID DISCHARGE DEVICE
First Claim
1. A liquid discharge device comprising:
- an installation case configured to receive a cartridge, the cartridge comprising;
a first liquid chamber storing a liquid;
a first flow path, one end of the first flow path communicated with the first liquid chamber, the other end of the first flow path communicated with the outside of the cartridge; and
a second flow path, one end of the second flow path communicated with the first liquid chamber, the other end of the second flow path communicated with the outside of the cartridge;
a tank comprising;
a second liquid chamber;
a third flow path, one end of the third flow path communicated with the outside, the other end of the third flow path communicated with the second liquid chamber, at least one of the first flow path and the third flow path configured to communicate with the first liquid chamber of the cartridge installed in the installation case and the second liquid chamber;
a fourth flow path, one end of the fourth flow path being below the other end of the third flow path and communicated with the second liquid chamber; and
a fifth flow path, one end of the fifth flow path communicated with the second liquid chamber, the other end of the fifth flow path communicated with the outside;
a head communicated with the other end of the fourth flow path;
a liquid level sensor;
an interface; and
a controller configured to;
receive, from the liquid level sensor, a first signal in a case a position of a liquid level in the second liquid chamber is equal to or higher than a predetermined position;
receive, from the liquid level sensor, a second signal in a case the position is lower than the predetermined position;
based on receiving the second signal after receiving the first signal, operate the alarm;
determine that the cartridge is installed in the installation case;
based on determining that the cartridge is installed in the installation case, read first information from a cartridge memory through the interface, the first information indicating an amount of liquid in the first liquid chamber; and
based on the first information, determine whether the operation of the alarm is cancelled.

Abstract
A liquid discharge device includes a case receiving a cartridge having a first liquid chamber, a tank having a second liquid chamber, a head, a liquid level sensor, an alarm and a controller configured to: receive a first signal or a second signal when a position of a liquid level in the second liquid chamber is equal to or higher than or lower than a predetermined position; operate the alarm when receiving the second signal after the first signal; cancel the operation of the alarm based on determining of installation of the cartridge; and operate the alarm based on determining that a first elapsed time from a time when determining the installation of the cartridge reaches a predetermined time and the second signal is received from the liquid level sensor without receiving the first signal.

21. A method executed by a controller of a liquid discharge device including a tank to be communicated with a cartridge, comprising:
-
receiving, from a liquid level sensor of the liquid discharged device, a first signal in a case a position of a liquid level in the tank is equal to or higher than a predetermined position; receiving, from the liquid level sensor, a second signal in a case the position is lower than the predetermined position; based on receiving the second signal after receiving the first signal, operating an alarm; determining that the cartridge is installed in an installation case of the liquid discharge device; based on determining that the cartridge is installed in the installation case, read a first information from a cartridge memory through the interface the first information indicating an amount of liquid in the installed cartridge; and based on read first information, determine whether that the operation of the alarm is cancelled.
