Abstract:
1. An inkjet printer comprising: an inkjet head configured to discharge ink droplets from nozzles formed in an ink discharging surface thereof; a head scanning unit configured to reciprocate the inkjet head relative to a recording sheet along a scanning direction parallel to the ink discharging surface; a wave shape generating mechanism configured to deform, in a predetermined range within a movable range of the inkjet head in the scanning direction, the recording sheet in a predetermined wave shape that has tops of portions protruding in a first direction toward the ink discharging surface and bottoms of portions recessed in a second direction opposite to the first direction, the tops and the bottoms alternately arranged along the scanning direction; a gap information acquiring device configured to acquire gap information related to a gap between the ink discharging surface and the recording sheet in each individual position of a plurality of top-formed positions and a plurality of bottom-formed positions within the predetermined range, each top-formed position being a position where a corresponding one of the tops is formed on the recording sheet, each bottom-formed position being a position where a corresponding one of the bottoms is formed on the recording sheet; an identifying device configured to, when the predetermined range includes a partial range in which the recording sheet is not placed, identify a top-formed position where the gap information is not acquired by the gap information acquiring device and a bottom-formed position where the gap information is not acquired by the gap information acquiring device, within the partial range; and a notification device configured to provide a notification, in a case that the identifying device identifies at least one of the top-formed position where the gap information is not acquired by the gap information acquiring devise and the bottom-formed position where the gap information is not acquired by the gap information acquiring device.
