An inkjet recording apparatus comprising: an ink tank forming an ink chamber and including an injection inlet; a recording head configured to eject ink retained in the ink chamber to record an image on a sheet; an ink sensor positioned to sense ink in the ink chamber; a monitor; an operation panel configured to receive user input; a controller configured to control operation of the recording head, the monitor, and the operation panel, characterized in that the controller is configured to: receive a completion signal indicating completion of ink injection; receive a first signal or a second signal from the ink sensor based on whether a predetermined amount of ink is sensed in the ink chamber, the first signal corresponding to the ink sensor sensing the predetermined amount of ink and the second signal corresponding to the ink sensor not sensing the predetermined amount of ink; based on the completion signal and receipt of the first signal, control the monitor to perform inquiry processing to display inquiry information on the monitor regarding whether ink injection into the ink chamber is completed, the inquiry processing allowing receipt at the operation panel of a response to the inquiry information; based on the completion signal and receipt of the second signal, control the monitor to perform notification processing to display a notification on the monitor that is based on the ink sensor not sensing the predetermined amount of ink. an ink tank forming an ink chamber and including an injection inlet; a recording head configured to eject ink retained in the ink chamber to record an image on a sheet; an ink sensor positioned to sense ink in the ink chamber; a monitor; an operation panel configured to receive user input; a controller configured to control operation of the recording head, the monitor, and the operation panel, characterized in that the controller is configured to: receive a completion signal indicating completion of ink injection; receive a first signal or a second signal from the ink sensor based on whether a predetermined amount of ink is sensed in the ink chamber, the first signal corresponding to the ink sensor sensing the predetermined amount of ink and the second signal corresponding to the ink sensor not sensing the predetermined amount of ink; based on the completion signal and receipt of the first signal, control the monitor to perform inquiry processing to display inquiry information on the monitor regarding whether ink injection into the ink chamber is completed, the inquiry processing allowing receipt at the operation panel of a response to the inquiry information; based on the completion signal and receipt of the second signal, control the monitor to perform notification processing to display a notification on the monitor that is based on the ink sensor not sensing the predetermined amount of ink. receive a completion signal indicating completion of ink injection; receive a first signal or a second signal from the ink sensor based on whether a predetermined amount of ink is sensed in the ink chamber, the first signal corresponding to the ink sensor sensing the predetermined amount of ink and the second signal corresponding to the ink sensor not sensing the predetermined amount of ink; based on the completion signal and receipt of the first signal, control the monitor to perform inquiry processing to display inquiry information on the monitor regarding whether ink injection into the ink chamber is completed, the inquiry processing allowing receipt at the operation panel of a response to the inquiry information; based on the completion signal and receipt of the second signal, control the monitor to perform notification processing to display a notification on the monitor that is based on the ink sensor not sensing the predetermined amount of ink.
