thanks for these data. I have saved this log along with a few others. I
am currently working (slowly) getting full support for G4050 transparency
adaptor support. When finished, I may look into adding 700F and 5600F to the
gl847 scanners. But working without a test device is really difficult and
slow. So it would be great if someone with such a scanner could step in.
