Inkjet printer and method for acquiring gap information

摘要

An inkjet printer is provided, which is configured to acquire gap information related to a gap between an ink discharging surface and a recording sheet in each individual position of top-formed positions and bottom-formed positions within a predetermined wave-shape generating range, identify, when the predetermined wave-shape generating range includes a partial range in which the recording sheet is not placed, a top-formed position where the gap information has not been acquired and a bottom-formed position where the gap information has not been acquired, within the partial range, complement the unacquired gap information in the identified top-formed position with a value determined based on the respective pieces of gap information acquired in other top-formed positions, and complement the unacquired gap information in the identified bottom-formed position with a value determined based on the respective pieces of gap information acquired in other bottom-formed positions.

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 scanning unit configured to reciprocate the inkjet head relative to a recording sheet along a scanning direction parallel to the ink discharging surface; a sheet deforming 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 particular shape that has a plurality of tops and a bottom farther away from the ink discharging surface than the plurality of tops in a particular direction orthogonal to the ink discharging surface, the bottom being positioned between the plurality of tops in the scanning direction; and a control 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 bottom-formed position, each top-formed position being a position where a corresponding one of the plurality of tops is formed on the recording sheet, the bottom-formed position being a position where the bottom is formed on the recording sheet;identify a specific top-formed position where the gap information is not acquired, from among the plurality of top-formed positions; andcomplement the gap information that is not acquired in the identified specific top-formed position, with a value determined based on the respective one or more pieces of gap information acquired in one or more top-formed positions other than the identified specific-top-formed position of the plurality of top-formed positions.
