Abstract

A controller determines the amount of driving by a sub-scanning driver and the number of nozzles to be used in accordance with a maximum amplitude of vibration of an inkjet head in a sub-scanning direction, where the maximum amplitude is detected by a displacement detecting sensor when the inkjet head is moved in the sub-scanning direction before starting printing. Then, while moving the inkjet head in a main-scanning direction, the controller performs printing by selecting nozzles to be used in accordance with displacement of the inkjet head in the sub-scanning direction detected by the displacement detecting sensor.
