I also have a 1220S - the lamp does stay on for a while, but eventually
does shut off. it seems to be controlled by the scanner - as you said,
there doesn't seem to be any way to do it via the driver.
I have the same problem when I run under Win95, too.
Maybe I'll check the UMAX web site....
P.S. I believe that they use a cold cathode fluorescent lamp - nowadays
these lamps have lifetimes in excess of 25,000 hours to 50% luminance.
I've seen some lamps quoted now in excess of 40K hours.
