Bug Description

The vendor backend does support duplex - the following command correctly produces a .pnm for each side:

scanimage --batch --ScanMode Duplex

I mean that simple-scan behaves exactly the same way as if Duplex were unselected. It only displays the image of the front side of the paper.

Looking at the log output, seems like the option value is not being passed to SANE - I would expect to see a log message like:

sane_control_option (6, SANE_ACTION_SET_VALUE, "Duplex")

In response to the previous comment, I unplugged the Epson scanner and re-ran the test - same result. New log file uploaded.

new versions of simple scan force the order of arguments passed to sane. some arguments reset other arguments, so maybe this was an issue here. could you please retest?

I can confirm this bug for a Samsung CLX-6220FX device running with Samsung's Unified Driver software. The command:
$ scanimage -b --doc-source "ADF Duplex - Long-Edge Binding"
correctly scans both sides of every page in the ADF (automatic document feeder), whereas setting "Scan side" to "Front and back" in simple scan doesn't produce output for both sides, only the front side for every page.

I am running 12.04 with the latest updates.

I can also confirm this with the Samsung CLX-6220FX on 13.04 Raring. As 'mtu' says, the scanner driver requires the option

--doc-source "ADF Duplex - Long-Edge Binding"

Same Problem for me with a hp device, should i open a new bug request?

HP Officejet Pro 8620
ubuntu 14.04
simple scan 3.12.1
hplip 3.15.4
(Ubuntu 14.04 supplies HPLIP 3.14.3 by default, which does not support my printer. (First supported Version is 3.14.4 -__- ) so i had to upgrade it manually...)

Works with xsane 0.998 flawlessly

Same problem here with HP printer "HP Color LaserJet MFP M476dn" on Linux Mint 17 (based Ubuntu 14.04.2 LTS).

Scanning duplex is working well in Xsane and gscan2pdf, but with Simple Scan only the front side of each page is scanned.

Additional info: gscan2pdf is working with interface "libsane-perl" and scanimage.

Linux Mint 17 (based Ubuntu 14.04.2 LTS)
hplip: 3.5.17 (LM17 comes with hplip 3.14.3, but printer needs 3.5.17)
simple scan: 3.12.1-0ubuntu1
Xsane: 0.998-5ubuntu1
gscan2pdf 1.2.3-1
