A volume-based dispensing control method is capable of enabling a pump to dispense a resin with greatly increased accuracy. The method includes: a preliminary dispensing step in which a resin is dispensed on one or more workpieces with a pump; a volume measuring step in which the workpieces passed through the preliminary dispensing step is scanned by an optical scanner to measure a dispensed resin volume; a corrected-volume calculating step in which a corrected volume of the resin to be additionally dispensed is calculated by using a difference between the dispensed resin volume measured in the volume measuring step and a predetermined dispensing volume; and a corrective dispensing step in which the resin is dispensed on the workpieces in light of the corrected volume calculated in the corrected-volume calculating step.
