Abstract: A transporting belt constituting a transport device transports a medium supported by a front surface in a transport direction. A removal unit includes a blade that comes into contact with the front surface to remove an adhering substance. A plurality of detectors detect a force received by the blade from the transporting belt or a change in the force. A display unit displays information. An adjustment unit is configured to adjust a position of the blade relative to the transporting belt. Each of the detectors are provided corresponding to a respective one of a plurality of regions into which the transporting belt is divided in the width direction intersecting the transport direction. When the control unit determines that there is an abnormal region among the regions based on detection results of the detectors, the control unit causes the display unit to display information indicating the abnormal region.
