You have eSCL, this is very good.

You may use "old" (without WSD) sane-airscan, and binary packages are 
available from here:


It seems to me, that your scanner erroneously announces itself as 
"http", but actually does "https". If automatic discovery doesn't work,
add the following line to /etc/sane.d/airscan.conf:

"EPSON WF-2850 Series" =

Please let me know, if my suspicions turn out to be true. And at this 
case, please send output of the following two commands, so I will be 
able to think on workaround. The commands are:

avahi-browse -rt _uscan._tcp
avahi-browse -rt _uscans._tcp

(note the difference "_uscan" vs "_uscans").
