Abstract
In order for skew relative to the transport direction to be detected in a sheet which is transported to a recording unit, a carriage is initially moved in a scanning direction to a first position and the sheet is transported in this state. Then, when the front edge of the sheet in the transport direction is detected by a second sensor, the carriage is moved in a direction so that the second sensor is no longer able to locate the front edge to a second position, which is separated from the first position by a regulating movement distance. Furthermore, the sheet is transported to where the second sensor locates the front edge of the sheet in the transport direction at the second position and skew in the sheet is detected based on this transport distance and the regulating movement distance.
