METHOD AND INKJET PRINTER FOR ACQUIRING GAP INFORMATION

摘要

A method is provided that is implemented on a control device connected with an inkjet printer, which includes an inkjet head having an ink discharging surface, a head scanning unit reciprocating the inkjet head relative to a recording sheet along a scanning direction parallel to the ink discharging surface, and a wave shape generating mechanism deforming 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 alternately arranged along the scanning direction, the method including acquiring gap information related to a gap between the ink discharging surface and each individual one of the tops and the bottoms on the recording sheet, and determining whether the gap information acquired for each individual one of the tops and the bottoms is abnormal.

主权项

1. A method adapted to be implemented on a control device coupled with an inkjet printer, the 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; and a sheet deforming mechanism configured to deform the recording sheet in a predetermined shape that has a top of a portion protruding in a first direction toward the ink discharging surface and a bottom of a portion recessed in a second direction opposite to the first direction, the top and the bottom being arranged along the scanning direction,the method comprising:
acquiring gap information related to a gap between the ink discharging surface and each individual one of the top and the bottom on the recording sheet; and determining whether the gap information acquired for each individual one of the top and the bottom on the recording sheet is abnormal.
