How can use Linux to scan from an Epson Stylus SX535WD printer/scanner connected directly to my home LAN? I am using Suse Linux 42.2 (Leap) (64-bit), but I imagine any answers may well be applicable to many other distributions. My system used to be Suse 13.¿2?, and I upgraded to 42.2 by following the upgrade instructions. I can print to the Epson via the LAN, so there should not be a connectivity problem.

¡The following is mainly some time ago and I have forgotten the details of what I was doing!

I tried the following tools and sources of information:

• 
  

  Epson: Linux Scanner Driver Download This sounded really promising. I installed iscan-bundle-1.0.4.x64.rpm as per instructions in README.rst with the plain command install.sh. If I start iscan or do gimp – File – Create – Scanning (iscan) I am told:

  
  
  

  
  

  Could not send command to scanner
  
  Check the scanner’s status

  
  

  
  
  

  Neither way gives me a chance to set anything up or any instructions.

  
  



• OpenSuse: Configuring Scanners is mainly about scanners connected directly to a computer, possibly then accessed by other computers in the LAN; also about professional network … all-in-one … scan to e-mail — but not about home devices connected directly to the networlk.

  Ask Ubuntu:

  
  
  

  • How to map network scanner gives instructions that may be specific to Ubuntu and are specific to a different printer/scanner model (Canon). It helped in so far as it directed me to http://www.sane-project.org/sane-mfgs.html, from which I concluded that in my case I needed to edit /etc/sane.d/epson2.conf, in which I suppressed the scsi, usb and net autodiscovery lines and added net 192.168.2.99 as the sole active line.

  
  

  • Why is saned disabled on boot Ubuntu 12.0 (Answer) talks about getting saned enabled by editing /etc/default/saned, which I did not have (but see below).

  
  


• man saned


• man xinetd

I first tried configuring a scanner with YaST but that seems not to be meant for scanners directly attached to the LAN.

I gather that I need saned; I see that it is listed in Network Service (xinetd) as implementing sane-port in YaST, but I had to click Enable first before I could activate or even see it.

• What other (possibly unwanted) consequences might enabling xinetd have? (The only other service listed as active is git, which is fine by me.)

I added sane-port there, as shown in man saned.
I tried enabling sane-port there, but scanner programmes still saw no scanners. I do have /usr/sbin/saned, from the package sane-backends. I tried copying the /etc/default/saned in Why is saned disabled on boot Ubuntu 12.0 (Answer) and changing RUN= to yes, but I had no user saned, nor did I know how one should be set up, so I changed the user to root.root. But then I saw on the man-page that one should not run it as root, so created group and user saned with id 450 (chosen by me) and 100 (automatically set by YaST) and selected them for sane-port in the xinetd configuration.
