I've just started using a Canon MX925. I've duplex scanned to my computer 2, 2-page documents (4 sides each) using the ADF. On one document, the final (4th) page extends the full height of the paper and is the right way up in the PDF. On the other, the text extends only a couple of inches from the top of the 4th page, with a page number at the bottom. In the PDF, this page is upside down!
Is this a known 'feature', or there something in the settings I don't know about?
