Abstract: A liquid-amount detecting apparatus detects the amount of a liquid in containers. The liquid-amount detecting apparatus includes a liquid detecting circuit and a determining unit. The liquid detecting circuit includes electrode units disposed so as to be in contact with the liquid in the containers, which becomes electrically conductive when in contact with the liquid, an impedance, and an AC-signal source. An AC signal not containing a DC component is input from the AC-signal source to the electrode units through the source impedance, and a signal representing the status of electric connection of the electrode units is output. Furthermore, based on the output signal, a binary signal representing the presence or absence of electrical connection of the electrode units is output. The determining unit determines the presence or absence of the liquid at the electrode units based on the binary signal output from the liquid detecting circuit.

Abstract: A negative pressure generated inside a liquid-ejecting head can circulate liquid between the liquid-ejecting head and a liquid tank, prevent the liquid from leaking out of nozzles while the liquid is circulating, and remove bubbles contained in the liquid. A head cartridge includes a printhead ejecting ink from ink-ejecting nozzles formed in a nozzle plate of the printhead, an ink-supplying conduit supplying the ink from an ink tank to an ink chamber in the printhead, an ink-refluxing conduit refluxing the ink from the printhead to the ink tank, and a liquid-delivering pump disposed on: the ink-refluxing conduit and circulating the ink between the printhead and the ink tank. The liquid-delivering pump is driven to generate a negative pressure inside the printhead to circulate the ink between the printhead and the ink tank.
