Abstract
A method for filling a liquid-discharge-head cartridge with liquid includes a first step in which a suction operation is performed at a first suction pressure while a suction member is moved along the discharge port row in the discharge-port surface at a first moving speed to suck the liquid in the liquid container to fill the discharge ports, and a second step in which a suction operation is performed at a second suction pressure, which is lower than the first suction pressure, while the suction member is moved along the discharge port row in the discharge-port surface at a second moving speed, which is lower than the first moving speed to remove bubbles in the flow path.
Claims7
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 operation is performed at a first suction pressure while a suction member is moved along the discharge port row in the discharge-port surface at a first moving speed to suck the liquid in the liquid container to fill the discharge ports;
- and
- a second step in which a suction operation is performed at a second suction pressure, which is lower than the first suction pressure, while the suction member is moved along the discharge port row in the discharge-port surface at a second moving speed, which is lower than the first moving speed, to remove bubbles in the flow path after the first step.
A method for manufacturing liquid-discharge-head cartridges comprising:
- a step of preparing a liquid-discharge-head cartridge including a liquid container for storing liquid, a discharge-port surface having a discharge port row consisting of a plurality of discharge ports through which liquid in the liquid container is discharged, and a flow path for communicating between the liquid container and the discharge ports;
- a first step in which a suction operation is performed at a first suction pressure while a suction member is moved along the discharge port row in the discharge-port surface at a first moving speed to suck the liquid in the liquid container to fill the discharge ports;
- and
- a second step in which a suction operation is performed at a second suction pressure, which is lower than the first suction pressure, while the suction member is moved along the discharge port row in the discharge-port surface at a second moving speed, which is lower than the first moving speed, to remove bubbles in the flow path after the first step.
