Abstract:
1. A method for filling a liquid-discharge-head cartridge with liquid, the liquid-discharge-head cartridge having a liquid container for storing liquid, a discharge-port surface having a discharge port row consisting of a plurality of discharge ports through which the liquid in the liquid container is discharged, and a flow path for communicating between the liquid container and the discharge ports, the method comprising: a first step in which a suction member moves along the discharge port row in the discharge-port surface while wiping the discharge-port surface and sucking the liquid in the liquid container through the discharge port at a first suction pressure; and a second step in which the suction member moves along the discharge port row in the discharge-port surface while wiping the discharge-port surface and sucking the liquid in the discharge port at a second suction pressure which is lower than the first suction pressure after the first step, wherein the first step corresponds to an outward moving of the suction member along the discharge port row, and the second step corresponds to a homeward moving of the suction member along the discharge port row.
