An apparatus and method for erasing incomplete andor pending jobs from a marking device’s non-volatile memory after a power loss. A housing side opening radially penetrates through an outer peripheral wall surface and an inner peripheral wall surface of the housing and communicates with the fluid suction opening of the body. A pixel matrix circuit and logic circuitry are formed on the active matrix substrate. The data flow control circuit is configured to control the transmit circuit’s processing of DMA descriptors for each DMA channel responsive to data flow control data in the DMA descriptors in the corresponding data structure. All that need be done is the configuration that is typically accomplished when H.
