the default area of the plustek backend is NOT A4, it's exactly the small
portion you currently see.
You might use scanimage --help to see the available options, i.e.:
    -l 0..215mm [0]
        Top-left x position of scan area.
    -t 0..297mm [0]
        Top-left y position of scan area.
    -x 0..215mm [126]
        Width of scan-area.
    -y 0..297mm [76.21]
        Height of scan-area.

Here you see the default area in brackets.
scanimage -x 215 -y 297 -format tiff >outputfile.tif
should give you the expected result.
