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 storing device configured to store gap information comprising: first gap information related to a first gap between the ink discharging surface and a first portion of the recording sheet, in a direction perpendicular to the ink discharging surface, the first portion being positioned in a first position on the recording sheet; and second gap information related to a second gap between the ink discharging surface and a second portion of the recording sheet in the direction perpendicular to the ink discharging surface, the second portion being positioned in a second position on the recording sheet, the first position and the second position spaced apart from each other in the head moving direction; and
a control device configured to calculate interpolation gap information related to an interpolation gap between the ink discharging surface and a third portion of the recording sheet based on the first gap information and the second gap information stored in the storing device, the third portion being positioned in a third position between the first position and the second portion in the head moving direction on the recording sheet.
