摘要
An image reading apparatus includes a moving unit, a first detecting unit, and a second detecting unit. The moving unit moves a calibration plate in the main scanning direction relatively to a reading apparatus. The calibration plate is a plate for calibrating the reading apparatus. The reading apparatus has a reading unit and reading glass. The reading unit is arranged in the main scanning direction. The reading glass is disposed on a reading surface side of the reading unit. The first detecting unit detects an abnormality on the calibration plate from reading results. The reading results are obtained in such a manner that, while the moving unit is controlled to move the calibration plate, the reading unit reads the calibration plate. The second detecting unit detects an abnormality on the reading glass from the reading results.
