|I recently acquired an HP Scanjet 4850 scanner. The document scanning
works with no problems. This particular scanner has a negative/slide
scanning component built in to the lid of the device. This includes a
separate lamp to illuminate the film for scanning. The lamp in the lid
comes when I run a hardware self test procedure but I have not
discovered any way to have the lamp come on when scanning using sane.
Is this capability supported?
