Many scanners offer a scan-to-email function. For example, on a Brother printer, load and scan your document, as usual, then select Send Email. Configure your settings and click OK. Your default email program will send the scanned document. If your scanner doesn't have this function, scan the document to PDF format (for the most flexibility), then save it to your desired location on your computer. Then, open your email program and send the scanned document or image as an attachment.
