How can I use a physical scanner to digitize a document?

To understand how to scan a document from scanner, first connect the scanner to your computer and turn it on. Place the document face down on the scanner glass or load it into the automatic feeder. Open the scanner application and select the document type, color mode, and resolution. Preview the page if the software provides that option. Once everything looks correct, start the scan and choose where to save the resulting file. You can usually save it as PDF, JPEG, or another supported format.
