I am sorry, but -b seems not to solve my problems ><<br>I want to activate the duplex features of DocketPort 685<br>(DocketPort 685 is a duplex scanner with two sensors, up and down)<br>to scan a name card and <b>get its images of front and back at the same time.</b><br>
<br>I've found an article teaching how to activate duplex feature through sane<br>but it is device-dependent. ( the artcicle is about Canon P-150 scanner)<br>The original link is here <br><a href="http://ubuntuforums.org/showthread.php?t=1671216">http://ubuntuforums.org/showthread.php?t=1671216</a><br>
According to the article , i've done the following steps<br>1. scanimage -L <br> output: device `genesys:libusb:002:003' is a Syscan/Ambir DocketPORT 685 flatbed <br> scanner<br>2. scanimage --help --device-name canondr:libusb:002:002 <br>
output is in the tail of this mail <br> (<b>the sensor field is blank, and i didnt found any useful option for enabling duplex features , which means it doesn't support duplex feature?</b>)<br><br>Could anyone kindly tell me that Is there any modification of source code (I've compiled sane on my own) or any other ways to use duplex feature of DocketPort 685 through sane ?<br>

You need to add the -b argument to scanimage, if you want multiple<br>
images. See man scanimage for details and other related options.<br>
