Inkjet printer and method for acquiring gap information

摘要

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.

主权项

1. 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 recording sheet deforming unit configured to deform the recording sheet in a predetermined shape that has a top portion of a portion protruding in a first direction toward the ink discharging surface and a bottom portion of a portion recessed in a second direction opposite to the first direction, the top portion and the bottom portion being arranged along the head moving direction a storing device configured to store gap information comprising:
a first piece of gap information related to a first gap between the ink discharging surface and the top portion of the recording sheet in a direction perpendicular to the ink discharging surface; anda second piece of gap information related to a second gap between the ink discharging surface and the bottom portion of the recording sheet in the direction perpendicular to the ink discharging surface; and a calculating device configured to calculate interpolation gap information to be interpolated over a segment between the top portion and the bottom portion on the recording sheet in the head moving direction based on the first piece of gap information and the second piece of gap information stored in the storing device.
