摘要： Aspects of a disclosure relates to a liquid discharge device enables previously disabled liquid discharge through a head after a cartridge including a first liquid chamber is replaced and before the liquid level in a second liquid chamber of a tank reaches a predetermined level or higher. Another aspect of the disclosure relates to a liquid discharge device that deactivates an alarm after a cartridge including a first liquid chamber is replaced and before the liquid level in a second liquid reaches a predetermined level or higher.

摘要： An inkjet recording apparatus to which a cartridge is attachable includes: a tank including a storage chamber and an outlet port; a recording portion including a damper chamber and a recording head; an ink passage; a pump configured to suck fluid in the damper chamber; a first switch; and a controller. After attachment of the cartridge, the controller is configured to perform an initial ink introduction process to supply the ink from the cartridge to the storage chamber. The initial ink introduction process includes: a first suction process to drive the pump for a first period of time in a state where the first switch is in a first state to allow ink in the storage chamber to be sucked toward the damper chamber; and after performing the first suction process, an open process to switch the first switch to a second state.

摘要： An inkjet recording apparatus includes: a first tank; a second tank; a recording portion including a first damper chamber and a second damper chamber; a first switch; a pump; a second switch; and a controller. The first switch is configured to be switched between a first state and a second state. The second switch is configured to be switched between a third state and a fourth state. After attachment of first and second cartridges to the inkjet recording apparatus, the controller performs an initial ink introduction including one of: a first drive process to drive the pump in a state where the first switch is in the first state and the second switch is in the fourth state; and a second drive process to drive the pump in a state where the first switch is in the second state and the second switch is in the third state.

摘要： A liquid discharge apparatus is configured to activate a first notification in a case where a liquid level of a tank is less than a threshold. In a case where a cartridge is installed after activating the first notification, a controller determines outflow amount Vcs of the liquid flowing into the tank based on the liquid amount of the installed cartridge, and controls a notification device based on the determined outflow amount Vcs.

摘要： A liquid discharge device is configured to display, on a display, an S_Empty notification screen in a state where a low level signal is not received from a liquid level sensor and a count value SN2 reaches a second threshold value Nth2. The liquid discharge device is configured to erase the S_Empty notification screen in a state where the low level signal is received after receiving a high level signal is received from an installation sensor.
