The attached sane_debug3.txt.gz was the result: 1) The scanner with TPU stopped flashing the led light, so was ready. 2) I started xsane with debug as above. 3) The Positive slide setting was already selected (from previous runs). 4) I clicked the Acquire preview button, and got the error window (Invalid op, I think) 5) I quit xsane to keep the debug log short. I will try to get a similar log when "Positive film" is selected, which should succeed. Hope this helps. It will take me some time to understand the log... ael
