Step 1: Load your document face-down into the paper feed at the top of the scanner.
Step 2: Press the "Email" button on the touch screen (see pic below)
Step 3: Enter a From: address (probably should be your own MIT email address), a To: address (where you want the PDF to get mailed)and optionally a subject and a message.
Step 4: Press the "Scan" button on the touch panel.
Step 5: Wait for the document to be fed through and scanned. You can look at the preview of the document and do some basic editing stuff, like rotate pages. When you are satisfied with the preview, press "Send".
Step 6: Stare at the little animation of the mail envelope flying across the globe. The document is being emailed to you. Have fun...
