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 11):
The inkjet recording apparatus according to  claim 1 , further comprising:\n a cover movable between a covering position covering the inlet to restrict injection of ink into the ink chamber and an exposing position exposing the inlet to an outside to allow injection of ink into the ink chamber; and a cover sensor configured to detect whether the cover is in the covering position or the exposing position, wherein the second state includes a plug OFF state and a switch OFF state, the power switching section in the plug OFF state interrupting supply of an electric power from an external power source, the power switching section in the switch OFF state being configured to supply an electric power to the controller and the cover sensor, wherein the memory further stores a refill inference flag, and wherein the controller is further configured to:\n while the power switching section is in the switch OFF state, in response to detecting through the cover sensor that the cover was moved to the exposing position, execute a first setting process to set the refill inference flag to a first value; \n in response to receiving the first operation in the query process, execute a second setting process to set the refill inference flag to a second value; \n in response to the power switching section being switched from the switch OFF state to the first state, execute a sixth determination process to determine whether the refill inference flag is set to either one of the first value and the second value; \n after determining in the sixth determination process that the refill inference flag is set to the first value, execute the query process; and \n in response to determining in the sixth determination process that the refill inference flag is set to the second value, leave the query process unattended.
