See  to check if sane supports your scanner. Install the sane package. If that fails, run the command again as root to check for permission problems. If that fails as well, check that your scanner is plugged into the computer. Sane provides many special backend options for numerous scanner types.

These distributions have an init system the first process started during booting of the computer and which governs its subsequent behaviour based on systemd.
On a machine with a scanner connected to a USB port the server , SANE with systemd can be socket activated check that the service is enabled. The saned daemon is started when a request is received on the server from a client and is stopped when the request is fulfilled.
This forms the basis for a scanner shared by the server to serve up an image of a document to an application on a client. Essentially, saned on the server and the net backend on the client are used to convert a non-networked or network-incapable scanner into a networked one.
Consult a backend's manual for information on whether the backend supports scanning over the network. For example, the epson2 and pixma backends do.
Other vendors also provide a means to access a network-capable scanner but there is generally a non-free aspect to what they offer, so configuration of their devices is not treated on this page. No changes need be made to this file for the vast majority of users.
For example, you could allow the local network using the following configuration, which will vary according to your network configuration: A first installation of libsane has the socket service disabled, so it would be necessary to enable and start it as described above.
Client Configuration It is essential to install libsane and, for testing the client's ability to see the networked scanner, it is recommended to install sane-utils.
Success in detecting the shared scanner with scanimage indicates probable success with other frontends. It's intended use is for the server which has a SANE-supported scanner to be able to export that scanner to clients on the network via a single SANE-specific, manufacturer-agnostic protocol.
Troubleshooting Make sure the saned user can access the scanner locally on the server. Having an ordinary user with or without permissions on the USB bus libpam-systemd might not be installed is of no consequence.
It is the saned user which needs the permissions. Bear in mind that sane-find-scanner does a generic USB scan; success indicates a user has sufficient privileges to access the USB devices. If the scanner works on the server but not remotely, make sure the saned. This is a known bug in the systemd unit. Network Scanner Configurations Scanning with a Network HP all-in-one aio -1 To scan over the network from a scanner on an HP aio one which is not connected by USB to a computer you need only to install libsane-hpaio without its recommended packages and pass the URI of the scanner to the frontend.
A non-free plugin might be required for the scanning function. Automatic discovery will happen via the print queue if both it and mDNS are available as discovery methods. For typing from a terminal you might find a simple alias sufficient. An hplip installation pulls in libsane-hpaio as a dependency and hplip provides the utility hp-makeuri. It can be used instead of the previous technique for finding a URI. A needed plugin can also be installed with hp-plugin. Scanning with a Network HP all-in-one aio -2 Many users will configure an HP aio machine by installing hplip or hplip-gui and setting up the printing side of the device with hp-setup.
Scanning should now be automatically available, as explained by a user on sane-devel and by an hplipopensource troubleshooting page. Without setting up the printing function of the aio the scanner should be detected by scanimage -L and the frontend should automatically run after doing xsane simple-scan xscanimage sharing a network HP aio scanner is not possible due to bugs and Network scanners from other vendors might work in sharing mode though.
Canon Multi-Function Printers and CanonScan Scanners via the Network If, according to the SANE project , your scanner is using sane-pixma as a backend, you need to make sure that: The scanner and your computer are located in the same subnet. If not, see below. UDP Ports and are open in your firewall. Opening Ports By default, Debian 10 buster uses nftables as the default firewall implementation; it is configured to allow all traffic.
But if you have problems with discovering the scanner you should probably check UDP ports and are open. Normally only scanners that cannot be auto-detected because they are on a different subnet should be listed here.
Host is the hostname or IP address of the scanner. The port number is optional and is normally implied by the method. Port is the standard port for mfnp , for bjnp. A scanner specific timeout value for the network protocol can be set using the bjnp-timeout parameter. The value is in milliseconds. Define scanners each on a new line. Quite recently, one or two backends using the eSCL protocol have made an appearence: sane-airscan. Inetd Configuration An alternative to systemd socket activation is to use openbsd-inetd.

SANE - Scanner Access Now Easy
For a network scanner please refer to SaneOverNetwork. The Project provides a collection of scanner backends drivers that can communicate with the scanner in order to operate it. Those scanners that SANE directly supports with backends are listed here. The first step on the road to successful scanning is to install libsane , which has the central library for operating scanners. The package also provides SANE's collection of scanner backends.

Also see the sane page for the version of sane that ships with Ubuntu Here are some tips if you do get stuck. Contents How can I find out if my scanner works with Ubuntu?
