Abstract
Official abstract text for this publication.
A conveying device has a conveying belt configured to convey a sheet. A printing device is configured to print an image on the sheet that is conveyed by the conveying device in a conveying direction. A plurality of sensors is arranged to be spaced away from each other in a main scanning direction that is perpendicular to the conveying direction. The plurality of sensors is configured to emit light to different detection regions on an outer peripheral surface of the conveying belt and to receive light reflected by the conveying belt. A controller is configured to execute a skew-detection-mark printing process of controlling the printing device to print a skew detection mark at positions passing the respective detection regions so that the skew detection mark extends over an end of the sheet in the conveying direction and the outer peripheral surface of the conveying belt.
