Abstract:
A head driving device includes a recording head, an input-and-output interface, and circuitry. The recording head includes a plurality of nozzles and a plurality of pressure generating elements corresponding to the plurality of nozzles. The input-and-output interface is configured to acquire correction information generated based on a chart image of a specific pattern for correcting a deviation amount of a landing position of each of the plurality of nozzles. The circuitry is configured to set the correction information acquired by the input-and-output interface and perform correction processing for correcting the deviation amount of the landing position on a driver for each of the plurality of nozzles of the recording head, in accordance with the correction information.
