Publication number: 20230391112Abstract: A printing apparatus includes a conveyance unit to convey a printing medium, a printing unit, a support member, a detection unit, and a control unit. The detection unit emits light in a direction toward a surface of the support member supporting the printing medium and outputs information indicating an amount of light that is reflected The control unit performs setting related to the detection unit output to set output from the detection unit such that a difference between a value indicating the detection unit output in detecting the light reflected from the support member and a value indicating the detection unit output in detecting the light reflected from the conveyed printing medium is equal to or greater than a predetermined magnitude. The control unit executes predetermined processing related to an end portion of the conveyed printing medium based on the set output from the detection unit.Type: ApplicationFiled: May 31, 2023Publication date: December 7, 2023Inventor: KENJI KUBOZONO
