Hmm, log data looks fine to me. TPU area is reported fine. 48.26 mm
by 231.14 mm is big enough to scan a strip of 6 negatives (that's what
the product spec says it can).
Just to make sure, the area reported does not have its origin at the
same location as the flatbed scan area. Maybe you are trying to set
scan areas based on the latter origin. If so, you shouldn't.
The log data you sent indicated a mostly white (or black, depending on
whether you look at the scan data before or after conversion from
negative to positive). Did you put an original on the scanner?
What does a default TPU scan look like? Can you put up an image so I
can take a look?
