sudo scanimage -L

## -> device `xerox_mfp:libusb:001:005' is a Samsung Samsung SCX-3200 Series multi-function peripheral


## Configure sane-Daemon to accept incoming connections
sudo nano /etc/sane.d/saned.conf

## --> Access list 192.168.0.0/24 --> Accept incoming from all over the network

## Start sane Service
systemctl status saned.socket

sudo systemctl start saned.socket
sudo systemctl enable saned.socket
systemctl status saned.socket

## Configure Backend for network connections
sudo nano /etc/sane.d/net.conf

## add pi IP-Adress e.g.: -> 192.168.0.24 

sudo nano /etc/default/saned

## add: -> RUN=yes

sudo sane-find-scanner

sudo ls -l /dev/bus/usb/001 # <- USB depends on where the device is connected

## Output shows you the owner of the scanner -> usualls "lp"

## Add owner of the scanner (lp) to the the saned group
sudo adduser saned lp
