How do I get iScan to detect my Epson network Scanner?

Question

I would like to install my Epson Scanner ( model WP-4535 ) in Ubuntu 16.04 (had it installed in 15.10).

I installed this

sudo apt-get install sane libltdl7 

then iScan from the epsonpage (1), which is supposed to be an all-in-one package. I installed it via ./install.sh which results in having the following iscan parts:

x@y:~$ dpkg -l iscan* | grep ii
ii  iscan                2.30.3-1     amd64        simple, easy to use scanner utility for EPSON scanners
ii  iscan-data           1.39.0-1     all          Image Scan! for Linux data files
ii  iscan-network-nt     1.1.1-1      amd64        Image Scan! Network Plugin

iScan still cannot communicate with the scanner, though it can be identified via the following command

scanimage -L
device `epson2:net:192.168.0.7' is a Epson PID 087D flatbed scanner

If I recall it from 15.10 (worked after hours of meh) , epkowa was the solution not epson2, but adding it manually via sudo nano /etc/sane.d/dll.conf doesn't work.

The ubuntuuser page (2), suggests installing ltdl7 packages, which seems to be important, but I have no clue, how to find it (same with the plugin):

iscan_2.X.X-1.ltdl7_i386.deb (32 bit) / iscan_2.X.X-1.ltdl7_amd64.deb (64 bit)

ggf. iscan-plugin-gt-1500_2.1.2-1_i386.deb (allgemein iscan-plugin-SCANNER_VERSION_ARCHITEKTUR.deb) oder z.B. etwas wie esci-interpreter-perfection-v330_0.1.1-2_i386.deb 

Also installed xsltproc (3), because of reasons, but didn't change it.

Any suggestions?; help appreciated!

Solution

Due to instant feedback, I post my comment as an answer - if you consider this a duplicate, feel free to delete - I still think, I shouldn't have to browse about 2 hours through different pages to install my *"$§%/( scanner in ubuntu, after this issue has been around for 2 1/2 years, though this probably isn't due to Ubuntu itself and surely not a problem of this community in particular...

Thanks to @belyid (1) I found the reason, in one of the dozen tabs I had opened during my research, while I was running with my head through a wall - edited epkowa.conf and added the ip of the scanner in the network, resulting in scanimage -L to mention epkowa, finding a scanner, and iscan to work with my printer. Thanks and out
