Multipage Scanning on S2825cdn

My printer is a Dell S2825cdn. It does a good job, but I have yet to master the scanning functions. It's easy to scan a single page into an application, such as Nuance Power PDF or IrfanView, but what I really want is to scan multiple pages into a single PDF. Nuance, for example, requires me to press after each page, which is annoying. The process works with a screen grab program called FastStone Capture, but the options are limited.

A scanning program was apparently included on the disk, but I don't know where that is. I looked on the Dell site to download it, but the site says that it installs automatically with the driver. It did not. It's possible that the program only installs with certain programs.

Suggestions?
