Most of the time a scanner by default, will scan a document in a tif or other image file format. That means that the scanned image is actually very similar to a photograph. In order to edit the text, you first have to convert the image using something that's called OCR software. OCR is a process that the software uses to look at a scanned document image and determine what characters are on the page. It's not always very accurate but that depends on the quality of the scan and on the OCR software being used. You must have received some sort of scanning software with the scanner. Hopefully it containes some sort of OCR software. Some scanners will save you this extra image manipulation by having a setting that allows you to scan directly to a word document. Usually in that configuration, the OCR software automatically knows to convert the scanned document image in order to automate the process. But either way, you first have to install the manufacturer's software. Hope this helps. Please remember to rate my answer. Thanks.
