Abstract: A liquid-printing apparatus, having a conveyer, a printing head, a liquid storage, a carriage, a scanning assembly, a remaining amount detector, and a controller, is provided. The printing head prints an image in a printing area ranging from a print-start position to a print-finish position along a scanning direction. The scanning assembly performs pass actions to move the carriage from a scan-start position to a scan-terminal position along the scanning direction.
