<p><code>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.<br>
<br>
Is this capability supported?<br>
