See page 19 of the manual. The scanner can only get to the max ppi of 120 film as the two 35mm frames side by side give you a total width much greater that a 35mm frame in portrait orientation.

    Ahh Okay, not the answer I was hoping for but that makes sense. Thank you

    Completely baffled as to why the maker of that holder wouldn't make one strip in the middle....3200 is probably fine - a topic for another thread I guess

    Exactly, the sensor is located behind a lens, their heights (both sensor and lenses) are varying according to the scanned format, to capture the negative field in focus; it works effectively exactly like an enlarger, which explains you can't get more on a larger field. This is the main difference with pro flatbed scanners whereas the sensor is travelling across the negative, bringing you the full resolution of the sensor for the entire field.
