Abstract:
An inkjet recording apparatus includes: a tank having an ink chamber; a recording head; a memory; a display; an operation interface; a power switching section; and a controller. The power switching section is configured to be switched between a first state where an electric power is supplied to the recording head and the display and a second state where supply of an electric power to the recording head and the display is interrupted. After the power switching section is switched from the second state to the first state, the controller executes a query process to: display a query screen inquiring whether the ink chamber has been refilled with ink; and receive one of a first operation and a second operation. In response to receiving the first operation indicating that ink chamber has been refilled with ink, the controller executes an initialization process to initialize a count value.

Claim (Index 12):
An inkjet recording apparatus comprising:\n a tank having an ink chamber configured to store ink therein and formed with an inlet through which the ink is supplied into the ink chamber; a recording head configured to eject the ink stored in the ink chamber toward a sheet to record an image thereon; a memory storing a first threshold value and a count value, the count value being indicative of an accumulated count value accumulated from an initial value; a display; an operation interface configured to output a first operation signal, a second operation signal, and a third operation signal; a power switching section configured to be switched between a first state and a second state, wherein under the first state, the power switching section supplies an electric power to both the recording head and the display, whereas under the second state, the power switching section interrupts supplying the electric power to both the recording head and the display; and a controller configured to update the count value toward the first threshold value in accordance with ejection of ink from the ink chamber, the controller being further configured to:\n receive the third operation signal from the operation interface; \n in response to receiving the third operation signal, switch the power switching section from the second state to the first state; \n after the power switching section is switched from the second state to the first state, execute a query process to:\n control the display to display a query screen inquiring whether the ink chamber has been refilled with ink; and \n receive either one of the first operation signal and the second operation signal from the operation interface, wherein the first operation signal indicates that the ink chamber has been refilled with ink, whereas the second operation signal indicates that the ink chamber has not been refilled with ink; and \n \n in response to receiving the first operation signal in the query process, execute an initialization process to set the count value to the initial value.
