Hi,<br>
I have a canon 2700f, and it ran once with sane. Until something happened.<br>
I'm not too sure what I changed, but the scanner stopped scanning. A<br>
couple of days ago I decided to reinstall the scanner and sane (1.0.1) from<br>
scratch. The result was the same symptoms as before:<br>
- the scsi host adapter to which the scanner is connected is correctly<br>
found during bootup<br>
- the scanner appears in /proc/scsi/scsi with the correct host, channel and <br>
ID<br>
- sane finds the scanner both with find-scanner and scanimage -L<br>
- the scanner correctly initializes when it's host adapter is initialized<br>
(I can hear and see the motor pulling the film sled around a bit)<br>
- I can select the scanner with xscanimage<br>
- when I scan something or want to grab a preview, the scanner doesn't do<br>
a thing (the motor doesn't do anything, no light), and xscanimage<br>
starts receiving weird random patterns as "scan" or preview<br>
The scanner works ok under windows, so the scanner itself is all right. <br>
I followed the installation instructions found at <br>
<a href="http://www.rzg.mpg.de/~mpd/sane/">http://www.rzg.mpg.de/~mpd/sane/</a><br>
while installing the scanner and sane (I tried with and w/o the separate <br>
backend). For those interested, a sample pattern can be found at<br>
<a href="http://www.heim1.tu-clausthal.de/~sriedel/out.pnm.gz">http://www.heim1.tu-clausthal.de/~sriedel/out.pnm.gz</a><br>
I'm a bit frustrated at the moment... Can anyone think of a cause for this <br>
phenomenon?<br>
<p>
