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.
