1-pass, TA
thats what my scanner says. But that is not the problem. You can scan normal
documents with the full size even if the TA is _installed_. Only if you tell
the scanner to _use_ trancparency, it switches the two lights and moves the
head. So from this moment on you must scan only 254mm. If you change the
input type back to "Flatbed", you have the full scan area again. So it seems
one must even tell the frontend (if it has a preview) that the area is
smaller while scanning transparent documents?!
I think I will search my sane documentation first, too many thinks I don't
know about the commuication between the frontend and the backend.

I would like to help, as time permits, but as I said, first I'll check the
docs now...
