    My Acer 610plus wait for the scanner to warm up OK. The way it happens is
    kind of annoying. You start xsane and nothing appears to happen until the
    warm up has finished. Then the xsane windows appear. It takes a long time
    for the scanner to time-out, and turn off its light, so I've yet to find
    out what happens if you need to re-light the light while xsane is running.
    Maybe the Acer620 doesn't work the same way, or maybe you are looking in
    the wrong direction.
