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 10):
The inkjet recording apparatus according to  claim 1 , further comprising a residual ink sensor configured to detect whether a level of the ink stored in the ink chamber is higher than or equal to a detection position,\n wherein the controller is further configured to:\n after the power switching section is switched from the second state to the first state, execute a fifth determination process to determine whether the level of the ink has changed from a position lower than the detection position to a position higher than or equal to the detection position based on a result of detection through the residual ink sensor; and \n in response to determining in the fifth determination process that the level of ink has changed from the position lower than the detection position to the position higher than or equal to the detection position, execute the query process.
