Abstract: An image scanning method is applied in an image scanning device which includes an input tray and a paper feeding sensor. The method detects whether there are papers on the input tray in step one. If there are papers, step two is executed. Otherwise, the method ends and an error is reported. In step two, papers are separated and fed. Whether the papers contact the paper feeding sensor is detected in step three. The method executes step four if the papers contact the paper feeding sensor, and ends the method with an error message otherwise. In step four, the method scans and detects whether an image of a fed edge of each of the papers is abnormal. If the image is abnormal, the method ends and an error is reported. Otherwise, scanning continues.
