Ubuntu – Device driver for Epson V600 Perfection

There are two versions of the iscan_2.29 deb-file, one with ltdl3 in the filename and one with ltdl7. For Ubuntu 12.10 you need to download the iscan_2.29.1-5~usb0.1.ltdl7_amd64.deb driver. The one you've picked (ltdl3) is for ubuntu 8.04 or earlier as explained in the FAQ at the bottom of the driver page. Also, iscan-data_1.22.0-1_all.deb needs to be installed first.

I have just gone through the process of installing the Epson iScan software following the recipe in the original question. There is just one stage missing to enable network access of the Epson scanner, to install iscan-network-nt.

The full recipe is as follows. For 32-bit machines the architecture labels will of course need changing to i386:

sudo dpkg -i iscan-data_1.25.0-1_all.deb
sudo dpkg -i iscan_2.29.3-1~usb0.1.ltdl7_amd64.deb
sudo dpkg -i iscan-network-nt_1.1.1-1_amd64.deb
sudo gedit /etc/sane.d/epkowa.conf

There are two entries to change in the epkowa.conf file, one for the network ip address (which you can get from the printer itself or from your router), and one to specify preference for the document feeder (although the latter seems to be brain-dead). After editing epkowa.conf it should contain the following lines somewhere:

net your.printer.ip.here
...
option prefer-adf

Not only does this enable the Epson scanner software, it allows XSane and Simple Scan also to correctly locate and interact with the scanner.
