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 8):
The inkjet recording apparatus according to  claim 7 , wherein the ink chamber includes a first ink chamber and a second ink chamber,\n wherein the count value includes a first count value indicative of the count value for the first ink chamber and a second count value indicative of the count value for the second ink chamber, wherein the residual ink sensor is configured to detect whether a level of ink stored in the first ink chamber is higher than or equal to a detection position, wherein the controller is further configured to:\n execute the fifth determination process to determine whether the level of the ink stored in the first ink chamber 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; \n after determining in the fifth determination process that the level of ink stored in the first ink chamber has changed from the position lower than the detection position to the position higher than or equal to the detection position, execute the initialization process to set the first count value to a first initial value without executing the query process targeting the first ink chamber; \n execute the query process targeting the second ink chamber; and \n in response to receiving the first operation in the query process targeting the second ink chamber, execute the initialization process to set the second count value to a second initial value.
