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

<i>&gt; Date: Thursday, February 25, 1999 11:17 AM</i><br>
<i>&gt; </i><br>
<i>&gt; I've recently acquired a UMAX Astra 1200S. The scanner seems to work</i><br>
fine<br>
<i>&gt; under SANE as far as the software goes (great job, guys!) but I've got</i><br>
one<br>
<i>&gt; question about the hardware.</i><br>
<i>&gt; </i><br>
<i>&gt; When I connected power (and nothing else) to the scanner, the imaging</i><br>
<i>&gt; lamp came on. When I connected the SCSI cable, the lamp stayed on.</i><br>
<i>&gt; I've tried SCSI bus resets, scanning images, setting every available</i><br>
<i>&gt; option in xscanimage and scanimage, and never has the lamp been off.</i><br>
<i>&gt; The lamp is still shining under the scanner cover to this day.</i><br>
<i>&gt; </i><br>
<i>&gt; Is this normal? Are the Windows drivers able to turn the lamp off?</i><br>
<i>&gt; Is the hardware incapable of turning the lamp off? Is it some kind of</i><br>
<i>&gt; funky solid-state lamp with a 100K-hour lifetime? </i><br>
<i>&gt; </i><br>
<i>&gt; If I seem paranoid it's because I'm too used to color-balanced imaging</i><br>
<i>&gt; lamps on other photographic devices which have lifetimes less than</i><br>
<i>&gt; 100 hours.</i><br>
