Abstract
A detection method for a liquid level of a storage tank is provided. The detection method determines that an optical sensor is for a liquid level detection purpose when a sensing value to a tank object is consistent with a first threshold condition. The detection method further determines the optical sensor as valid on liquid level detection when sensing values respectively corresponding to statuses of print material and non-print-material are consistent with a second threshold condition. During printing, the detection method starts/stops pouring print material into a storage tank when the sensing value of the optical sensor is consistent with a third threshold condition correspondingly.
