Alesh - Thanks for the tips. I just got the Workforce 610 last on Monday and now have the wireless scanning working following your instructions. At first I had problems with XSane, but Image Scan! worked fine. XSane failed with a "Failed to start scanner: Invalid argument.". I checked the dll.conf file and the epson and epson2 devices were commented out. I enabled epson2 and now both Image Scan! and XSane work great. Also, after removing saned from the command line, I got errors when running Synaptic, I reinstalled saned after everything was working and it did not cause any problems.
I just bought an Epson Workforce 630 for $80 and it prints OK wirelessly with the Workforce 615 driver in CUPS after configuring it as a network printer with an IP address.
Just to clarify what Jeephacker was talking about after poking around on the Avasys site and exactly what I did (FWIW

) I'm posting some text here.
Even with the errors I received, I'm able to scan wirelessly with the Avasys iscan software or xsane.
I did reinstall saned with Synaptic when it complained it was broken and all seems well for now.
I'm just happy I could follow a simple 30 step procedure!
From the Avasys site: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.
