• SANE (Scanner Access Now Easy)

• Arch Linux Wiki SANE
• Arch Linux Wiki SANE/Scanner-specific problems

USB connection requires the IPP protocol, normally designed for network printers, and can be used for USB printers.

• Arch Linux IPP-USB systemctl enable --now ipp-usb

• SystemD systemctl status saned.socket

• sane-find-scanner and note the libusb:000:000
• Note the permission ls -la /dev/bus/usb/007/008
• The device ID 0000:0000: lsusb
• Test if device is defined in configuration files: grep '0000.*0000' /etc/sane.d/*.conf

/etc/udev/rules.d/40-sane.rules ATTRS{idVendor}=="0000", ATTRS{idProduct}=="0000", ENV{libsane_matched}="yes", MODE="0664", GROUP="scanner"

• Expose network interface to local network: interface = all
• systemctl restart ipp-usb

• /etc/sane.d/dll.conf

Enable

• airscan or
• `"backend"

Determine backend support for hardware model: SANE: Supported Devices. For example, the backend for CanoScan LiDE 100 is genesys. ensure that it is present, and not commented out, in /etc/sane.d/dll.conf.

Configuration file to identify scanner:

• echo usb 0x00000 0x0000 > /etc/sane.d/name.conf
• Attempts to open library /usr/lib/sane/libsane-<name>.so[.version]

• Enable net, escl in /etc/sane.d/dll.conf or disable them and enable airscan enabled in /etc/sane.d/dll.d/airscan.

• Note the relevant device: airscan-discover

• Add host names, IP or subnets to "Access list": /etc/sane.d/saned.conf
• Enable "localhost": /etc/sane.d/net.conf

Enable network on device.

Create a network configuration. For example:

lan-ether-name.network

[Match]
Name=<network device>

[Link]
RequiredForOnline=false

[Network]
ConfigureWithoutCarrier=false

DHCP=yes
DHCPServer=true

IPv4Forwarding=true
IPv6Forwarding=true

IPMasquerade=both

Address=<IP for DHCP Server>

[Link]
RequiredForOnline=false

[DHCP]
UseDNS=true

The command airscan-discover should return devices served on IPv4 and IPv6.

• Note the relevant device: airscan-discover
• The device should be shared on network. For example:
  • "Device name (WSD)" = http://1.2.3.4:80/WebServices/Device, WSD

• Install "airscan"
• Add the relevant device noted on server to client configuration section [device] in /etc/sane.d/airscan.conf
  • The device should be found on access. For example: xsane or scanimage -L
• What scanner capabilities: http://<SERVER IP:PORT>/<eSCL, WSD>/ScannerCapabilities

Manual connect to server:

• Add server IP: /etc/sane.d/net.conf
• xsane [driver]:net:<SERVER IP>

• If scanner not found after setup, try unplugging and re-plugging the USB.
• Is the SANE port open on server? nmap <SERVER IP>
• export SANE_DEBUG_DLL=255 && scanimage -L
• scanimage -d "net:<SERVER IP>" --output-file test.png
• scanimage -d "airscan:e0:<SCANNER>" --output-file test.png
• systemctl status saned.socket provides information on number of connections that have been "Accepted" "Connected" "Refused".

Enable debug for airscan /etc/sane.d/airscan.conf

[debug]
trace   = ~/airscan/trace
enable  = true
