Abstract
An inkjet printer is provided that is configured to store a plurality of pieces of gap information respectively corresponding to a plurality of examined sections discretely arranged along a head moving direction on a recording sheet, each of the plurality of examined sections including a corresponding one portion of top portions and bottom portions on the recording sheet, and calculate interpolation gap information to be interpolated over a whole width in the head moving direction of at least one of a plurality of segments, each of which has a width in the head moving direction defined by two adjacent sections of the plurality of examined sections, based on the stored gap information.
Claims17
An inkjet printer comprising:
- an inkjet head configured to discharge ink droplets from nozzles formed in an ink discharging surface thereof;
- a head moving unit configured to reciprocate the inkjet head relative to a recording sheet along a head moving direction parallel to the ink discharging surface;
- a wave shape generating mechanism configured to deform the recording sheet in a predetermined wave shape that has top portions of portions protruding in a first direction toward the ink discharging surface and bottom portions of portions recessed in a second direction opposite to the first direction, the top portions and the bottom portions alternately arranged along the head moving direction;
- a storing device configured to store gap information related to a gap between the ink discharging surface and the recording sheet, the gap information comprising a plurality of pieces of gap information respectively corresponding to a plurality of examined sections discretely arranged along the head moving direction on the recording sheet, each of the plurality of examined sections including a corresponding one portion of the top portions and the bottom portions on the recording sheet;
- and
- a calculating device configured to calculate interpolation gap information to be interpolated over a whole width in the head moving direction of at least one of a plurality of segments, each of which has a width in the head moving direction defined by two adjacent sections of the plurality of examined sections, based on the gap information stored in the storing device.
