The Windows Fax and Scan utility enables you to scan documents and pictures. Before you can scan documents and pictures, you must have a scanner installed on your computer. Your scanner must be listed in the Devices section of the Devices and Printers Control Panel window. To check to see if your scanner is properly installed, open the Device Stage. Choose StartâDevices and Printers.
Flatbed scanners let you scan an array of documents including photographs, loose documents and pages within a book as well as any item that can lay flat on the scanner's surface. The devices interface with Windows, Mac and Linux systems and come with user-friendly application programs.uring the scanning process, documents lay flat on the device's glass platform and do not have to move through a series of feed rollers like drum scanners. This reduces the risk of the documents being damaged or getting caught by the rollers inside of handheld or drum scanners.
