I've since a few months a new HP 3800 that works OK for its range.
I do not use it everyday.
However it seems that the supporting programs given by HP with the
scanner IMPOSE to Windows XP to turn the scanner on *as soon* as you
put your computer on (either after a real switching off or automatic
pause of the computer).After ten minutes of non-use of the scanner the
lamp turns off, but it's not really a good way to look at the use of a
scanner.
I explored the HP program and did not find a way to avoid this
annoying sequence. I prefer to be able to decide myself if the scanner
has to turn on when I need it.

Does somebody have a solution to alter the automatic switching on of
this HP 3800 scanner??
Thanks in advance for any clue.
