Bringing Party Favors to Hell

I am going to reveal my ignorance here-- how does one scan a document which is several pages long and create a .pdf file wherein the pages are sequential within a single file, as opposed to having to open each page as a separate file? I've been asked to put the CV and recommendation letters of a job candidate into such files and I have no idea how to do it. We have two regular flatbed scanners and I know how to use them for single-page or single-image but it's the multiple-page thing that has me baffled.

Help me Obi-Wan Flist, you're my only hope!
