Same here with the 1200S... I also noticed that<br>
scanimage --mode col -x 4in -y 6in<br>
ignores the -x parameter, you need to put the '--mode col' at the end...<br>
(and 10-bit doesn't work in xscanimage and slow scan doesn't work either.<br>
but the defaults work :-) )<br>

<i>&gt; Subject: Clueless about Umax 1220S gamma </i><br>
<i>&gt; </i><br>
<i>&gt; My Umax 1220S tends to scan darker that the actual image being scanned. I</i><br>
<i>&gt; can usually correct for this by setting the gamma &gt;1 in color mode. In</i><br>
<i>&gt; grey-scale or line-art mode, the scan also comes out darker. So I try to</i><br>
<i>&gt; change the intensity gamma under grey-scale, but the picture turns out</i><br>
<i>&gt; either black or is washed out (nearly all grey). Can someone help me set</i><br>
<i>&gt; the correct intensity gamma for b/w? I wish xscanimage or scanimage has a</i><br>
<i>&gt; brightness control for this scanner.</i><br>
<i>&gt; </i><br>
<i>&gt; Sorry if I sound clue-less; I'm new to scanning.</i><br>
