Abstract
A method for a multi-function scanner for scanning a document with a laser/anti-counterfeit mark includes the steps of: pre-scanning the document to obtain a preview image; recording a zone of the laser/anti-counterfeit mark selected by a user on the preview image as a marked zone; using a visible light source to scan the document so as to obtain a first image corresponding to the document excluding the marked zone; using an infrared right source to scan the document so as to obtain a second image corresponding to the marked zone; and combining the first image with the second image.
