A scanning machine (10) includes a scan surface (12) for receiving a page or pages to be scanned. A motion detector (20) monitors the copy surface to detect movement of the pages. In response to detecting a cessation of motion on the scan surface, the motion detector generates a trigger signal which causes a capture circuit (30) to capture an image of a page on the scan surface. If, during the capture of the page image, the motion detector detects motion of the page, the motion detector generates an abort signal which terminates capture of the image and empties a buffer memory (32). Once cessation of motion of the page is again detected, another trigger signal is issued and another attempt is made to capture an image. In this manner, scanning is started and stopped by natural, simple gestures without the operator pushing buttons.
