Abstract:
Even when a contact connection failure of electrical connection occurs between a recording head including a recording element substrate, and a recording apparatus, continuous driving of the same heat generating resistive element is suppressed. Blocks in which heat generating resistive elements are not driven are prepared beforehand in a selection target of blocks to be driven in a time-division manner. When an input signal is in a predetermined condition, the block selection target is set to blocks in which heat generating resistive elements are not driven.
