Abstract:
Provided is a printing apparatus including a sensor unit for measuring a moving state of a sheet by optically detecting a surface of the sheet conveyed by a conveying unit. The sensor unit measures and compares the moving states of the sheet at a first measurement position and a second measurement position which are distinct from each other in a main scanning direction, to thereby obtain information on a skew state of a skew component of the moving sheet.
