Why does my Adobe Reader do this?

Factual Questions
1

When I scan a document at “100%” using my HP Printer/Fax/Scanner, I do so specifying a pdf format. However, when Adobe Reader opens it, it does so at 198% of the actual size?

Why does this happen and how can I get Adobe Reader to stop doing it?

Thanks.

Adobe Reader: Edit/Preferences/Page Display/Zoom - set to 100%. See if that works?
