[sane-devel] Microtek SlimScan C3, output always a black image

[Jose Sanchez]

Hi Karsten,
thanks again for the help.

You were right my BIOS was configured with ECP+EPP I leave it as EPP and 
the image was not stretched neither shifted.

I noticed,as you said, that there are some fine vertical stripes on the 
scanned images.  I am willing to help in what ever you need to fix this 
problem.  Just tell me what to do.

Well this error appeared when I was looking for help in the suse mailing 
list, then they told me to post my problem in the sane development list. 
 In the log file I sent they told me there was the following line:

scanimage: argument without option: `y20'

However, I ran it again exactly as before and I was looking for that line and I don't find it.  I attached the zip file with the scanned image, the new log file and the config file.  

I hope this will help in something, tell me what you need I and will be 
glad to help.  

Thanks

Jose
