Abstract:
A driving pulse for air bubble removal flushing which is a first maintenance pulse is a driving pulse which removes air bubbles in an ink flow path of a recording head, a driving pulse for thickened ink discharge flushing which is a second maintenance pulse is a driving pulse which removes thickened ink, thereby stabilizing a meniscus, and in a maintenance process which restores ejection capability of the recording head, after an air bubble removal flushing process is executed by using the driving pulse for air bubble removal flushing, a thickened ink discharge flushing process is executed by using the driving pulse for thickened ink discharge flushing.
