You have told the backend (scanner driver) that you want duplex data, but you have not told the frontend (scanimage) that it should grab more than one page. Try this instead:<br><br>scanimage -d canon_dr:libusb:002:006 --source 'ADF Duplex' --resolution 100 --format=tiff -b<br>
<br>This will produce images in your current directory called out1.tif, out2.tif, etc. These names can be changed, see scanimage manpage.<br><br>Also, please note, that support for this machine is somewhat basic in sane 1.0.20. In the last week I have added calibration and fixed many bugs. I would HIGHLY suggest that you upgrade to a recent sane-backends git snapshot, the scanner will be much more useful and the image quality significantly improved.<br>

Dear All ,<br>
I am posting for the first time . I am not a developer . But I was testing sane-1.0.20 backend on Canon DR-2050 C.<br>
I am using Mandriva Spring 2009.<br>
<br>
Using the following Command I am able to Scan but not able to use the Duplex Feature . Result is single page scan similarly to ADF Front<br>
<br>
# scanimage -d canon_dr:libusb:002:006 --source 'ADF Duplex' --resolution 100 --format=tiff > 2image.tiff<br>
<br>
Please note ,I have also tried the double quotes .ie "ADF Duplex" but same results . Kindly guide .<br>
<br>
Even after I removed the source option , the size of the file remained the same .<br>
<br>
I think , I am few steps away from configuring it successfully . Please help and guide .<br><font color="#888888">
