This scanner cannot distinguish DL from A3 or LT from A4.

When the paper is loaded into ADF by Object position (Load object), this scanner detects paper size assuming the orientation is portrait.

After the paper is ejected from ADF by Object position (Unload object), this scanner detects the orientation, and paper size.

This bit (b6) only valid after Object position (Load/unload object) is completed.

This byte is same regardless of front-side or back-side of the document.
