    摘要: An inkjet recording apparatus includes a heating unit configured to produce thermal energy for discharging ink, and two electrodes which electrically connect with each other through the ink. Voltage is applied between the two electrodes, and a current value flowing through the ink is measured. Whether the ink is discharged or not is determined by determining whether the current changes when the heating unit is driven.

    摘要: This invention relates to an element substrate capable of confirming an electrical connection status before a printhead malfunctions. The element substrate is a substrate for a printhead, which is detachable from a printing apparatus and includes a plurality of printing elements, a logical circuit for controlling the printing elements, and a voltage application terminal for applying a driving voltage to drive the printing elements. The logical circuit is driven at a voltage lower than the driving voltage. The element substrate includes a connection status output circuit which outputs a signal reflecting the electrical connection status between the printhead and the printing apparatus on the basis of the driving voltage.
