It's a feature that can be turned on the confidential documents but I don't think it's actually on by default.
You can check for it anyway, just print a document then attempt to scan it, if it's got the track marks it will refuse to scan because one of the things the track marks do is block scanning, although you can still take a photo of it because the camera probably won't be able to see the track marks so it's not 100% secure. In fact it's largely considered an obsolete security method these days, along with pink flimsies.
