You need to tell scanimage what device you want to talk to _before_<br>
|
|
specifying any device-specific options. In your case, something<br>
|
|
like this should work:<br>
|
|
<p>
|
|
scanimage -d mustek:0x36b --resolution 100<br>
|
|
<p>
|
|
It's a bug that the SANE backend picks a default resolution of 18 dpi<br>
|
|
when the smallest supported value is 51. A patch would be welcome.<br>

Rene> Hi there! I use a Mustek 600 II N scanner. 'scanimage -L'<br>
|
|
Rene> returns:<br>
|
|
<p>
|
|
Rene> device `pnm:0' is a Noname PNM file reader virtual device<br>
|
|
Rene> device `pnm:1' is a Noname PNM file reader virtual device<br>
|
|
Rene> device `mustek:0x36b' is a Mustek MFC-06000CZ flatbed scanner<br>
|
|
<p>
|
|
Rene> Looks quite nice I think, the scanner moves about a centimeter<br>
|
|
Rene> up and down, lamp goes on, no problem..<br>
|
|
<p>
|
|
Rene> But when I acctually want to scan an image the scanner gives<br>
|
|
Rene> me the same action as the 'initialisation' as mentioned above<br>
|
|
Rene> but then locks up. CTRL-C sais: stopping scanner... but this<br>
|
|
Rene> has no effect I have to kill the scanimage process and a 0<br>
|
|
Rene> byte output file remains.<br>
|
|
<p>
|
|
<p>
|
|
Rene> another strange thing:<br>
|
|
<p>
|
|
Rene> --resolution 51..600dpi (in steps of 1) [18] Sets the<br>
|
|
Rene> resolution of the scanned image. (look at the default value<br>
|
|
Rene> and the range given)<br>
|
|
<p>
|
|
Rene> and when I do:<br>
|
|
<p>
|
|
Rene> # scanimage --resolution 100<br>
|
|
<p>
|
|
Rene> I get: scanimage: unrecognized option `--resolution'<br>
|
|
<p>
|
|
Rene> the --preview option also makes scanimage lock up.<br>
|
|
<p>
|
|
Rene> Anybody got an answer?<br>
|
|
<p>
|
|
Rene> Thanks in advance!<br>
