Hello, I have installed this version and the scanner is running for me

Yes, individually scanned pages can be merged into a single document. This can be done using the supplied software or other document management tools that allow files to be merged. The software supplied with the Brother DSmobile DS-640 supports functions such as scanning to a file or image format, making it easier to combine pages.

Indeed, after several searches, this product does not have a duplex function. We will correct this.
