Abstract
A paper transport device is configured to independently drive a paper ejecting roller when predetermined abnormal events occur. When paper-jamming occurs and if no paper is present downstream of a jammed paper or a preceding paper that is present most downstream is located upstream of a predetermined position, the paper ejecting roller is stopped to prevent ejection of papers outside of the paper transport device. When paper-jamming occurs and if a preceding paper that is present most downstream is located downstream of the predetermined position, the paper ejecting roller is independently driven to complete ejection of the preceding paper.
