Abstract
A controller for a liquid discharging device generates a correction chart including a reference pattern and a correction part, using a liquid discharged from a liquid discharge head, the liquid discharge head having a plurality of nozzles that are arranged to form a nozzle array. The controller drives a predetermined number of the plurality of nozzles to form the reference pattern on the recording sheet along a direction of the nozzle array, the predetermined number being a number equal to or less than a total number of the plurality of nozzles of the nozzle array, and drives a number of the plurality of nozzles that is different than the predetermined number of nozzles driven in forming the reference pattern, to form the correction pattern on the recording sheet along the direction of the nozzle array.
