Publication number: 20220234346Abstract: A processor of a printer conveys a platen relative to a head in a conveyance direction, toward a printing position. The printing position is a position at which a nozzle surface of the head faces the platen in a discharge direction. The printer is provided with a first sensor. The first sensor detects a print medium positioned at a first detection position. The first detection position is a position separated from the nozzle surface in the discharge direction. When the print medium is detected by the first sensor after a start of conveyance of the platen, the processor moves the platen relative to the nozzle surface and separates the platen from the nozzle surface in the discharge direction. After that, the processor conveys the platen relative to the head in the conveyance direction, toward the printing position.Type: ApplicationFiled: January 25, 2022Publication date: July 28, 2022Inventors: Tetsuro KOBAYASHI, Shuichi TAMAKI
