   I'm the lead developer for "Image Scan! for Linux", a simple graphical
   user interface for SEIKO EPSON scanners and all-in-ones (loosely built
   around the SANE API).

   A network setup could be made to work by setting up `saned` on the
   server machine to accept connections from the client.  On the
   server side, `saned` would access the device through a backend that
   supports the RX685.  On the client you can then use any SANE
   frontend via the SANE net backend.

In this case, the device is connected to a print server (a cheap
router box with a USB connection for attaching a printer), and there's
no possibility of running anything on the print server box.

   I'd try using the device on the server machine directly first with
   a simple SANE frontend like `scanimage` first.  Next, try using it
   via localhost and `saned`.  If that all works, try it from the

   Note that network related restrictions (tcpwrappers,
   packet-filtering) may all get in the way before you even get to the
   SANE part of the story.

   Which backend are you using?  I'd hazard a guess that the RX685
   works fine with the same backend.

   At least the external `epkowa` backend is known to work (but has
   never been tested on the Mac, AFAIK).  It is part of "Image Scan!
   for Linux" and available at:


   For the RX685 no non-free binary-only parts are needed.

I use the free epkowa backend (distributed as part of the iscan
package) with the RX580, which is probably very similar to the RX685.
However, I'm doing it on Linux, not OS X.
