发明名称 Element substrate, printhead, head cartridge, printing apparatus, and method for confirming electrical connection status of printhead and printing apparatus
摘要 An element substrate capable of independently confirming an electrical connection status with a logic power source without increasing costs due to increasing the number of terminals or the like. The element substrate includes a connection status output circuit that outputs a signal in response to a connection status of a logic power source input terminal, or a connection status of input terminals of each of a print signal, a clock signal, a drive signal, and a latch signal, and a connection status output terminal that outputs an output signal from the connection status output circuit.
