Abstract:
A recording position control device includes head units, edge sensors, head movers, a controller, and a timer. The controller performs an original-point determination operation of moving the head units to an original point and to control the head movers to move the head units in a direction to correct meandering of a recording medium. The controller performs a second round of the original-point determination operation after performing a first round of the original-point determination operation. The timer measures, as a measurement time period, a time period from when the controller issues an execution command of the second round to when the controller receives a completion status of the second round. In a case in which the measurement time period is equal to or shorter than a first threshold time period, the controller determines that the original-point determination operation of the head units has failed to be normally executed.
