Epson BX635FWD - "Error during Device I/O" when scanning using ADF

Asked by Joe Taylor

I am currently using:

Epson BX635FWD printer/scanner over wi-fi connection

Ubuntu 12.04 LTS
libsane-epkowa.so.1.0.15
gscan2pdf 0.9.32

Image Scan! for Linux as follows (from http://download.ebz.epson.net/dsc/search/01/search/?OSC=LX)
iscan_2.28.1-3.ltdl7
iscan-network-nt-1.1.0-2

Scanning using the flatbed mode works fine. However, when using the auto document feeder, I get a dialog of "Error during Device I/O", and the printer locks up in "Scanning" mode with the "Auto" light flashing.

Any suggestions as to fixes? Any way I could get some more verbose error information? "Error during Device I/O" isn't particularly informative.

A note for anyone else with the same problem - following these steps solved it - particularly note step 5.

To set up your device for scanning via its network interface, follow the steps outlined below:

1. Download and install the latest version of Image Scan! for Linux from here.
2. If your device has a supported network interface, the iscan-network-nt plugin will also be available for download. Download and install the version appropriate for your system.
3. Now configure your device for network access. You need to set or obtain the IP address of the device. Please consult the product manual for details on how to do this.
4. Configure Image Scan! for Linux to connect to your device by editing /etc/sane.d/epkowa.conf. You need administrative privileges to do so. Read the instructions in the file about network configuration and add an entry for your device as indicated.
5. Finally, disable the conflicting epson2 SANE backend. You can do so by changing the line consisting of "epson2" to "#epson2" in /etc/sane.d/dll.conf. This will require administrative privileges.
