Abstract
The liquid discharge device determines a signal received from an installation sensor in response to receiving a discharge instruction, and when determined that a high level signal is received, control executing image recording in a first mode in which a waiting time Tw1 is set, and control executing image recording in a second mode in which a waiting time Tw2 is set.
Claims7
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 an 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 including a second liquid chamber, the tank comprising:
- a third flow path, one end of the third flow path communicated with the outside of the tank, 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 located below the third flow path 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 of the tank;
- a head communicated with the other end of the fourth flow path;
- an installation sensor;
- and
- a controller configured to:
- determine whether one of a first signal and a second signal is received from the installation sensor, the first signal indicating that the cartridge is not installed in the installation case, the second signal indicating that the cartridge is installed in the installation case;
- execute a first mode of discharging a liquid through the head, in which a liquid discharge amount through the head per unit time is a first amount in the first mode, based on receiving the discharge instruction to discharge a liquid through the head and determining that the first signal is received;
- and
- execute a second mode of discharging a liquid through the head, in which a liquid discharge amount through the head per unit time is a second amount larger than the first amount, based on receiving the discharge instruction to discharge a liquid through the head and determining that the second signal is received.
