Abstract
Although a conventional method of inspecting an ink discharge state in which the temperature change of the heater is detected enables accurate and high-speed inspection, due to the situation in which the inspection was performed, appropriate post-processing depending on the situation cannot be executed based on a result of the inspection. Therefore, it is necessary to determine the ink discharge state in detail. A plurality of modes are provided in accordance with the purpose of performing an inspection of the ink discharge state, and a discharge inspection threshold is provided for each of these modes. By selectively executing or continuously executing these modes, it is possible to determine the ink discharge state in more detail.
