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. If the scanner is not supported by SANE, the backend and other files will have to be obtained from the Debian archives or the vendor.
A notable free backend source requiring this step is the one for the all-in-one machines from HP. The next two sections assume you have the backend and other files that SANE or the vendor supply. Your scanner should work out-of the-box with a frontend without bothering with any of the next steps, but it is as well to be aware there are troubleshooting procedures that can be followed.
The SANE manual lists the backends available. Install sane-utils and see if the scanner is detected with sane-find-scanner Hopefully, you will see your scanner found.
If the result is different from what you expected, first make sure your scanner is powered up and properly connected to your computer. No SCSI scanners found. It may or may not be supported by SANE. A scanner has correctly been located on Bus as Device If access to this device had also been denied as was access to the other USB devices the permissions on the USB bus would have had to be looked at.
In the context of a local USB device that an ordinary user has permisssion to access, the positive response indicates that SANE has a backend to support the scanner. The file should be viewable with an image viewer such as imagemagick Permissions It is not necessary for a locally logged-in user to be in the scanner group. Permissions on the scanner device are automatically taken care of by the kernel and those on the USB bus are granted to a user by udev, given that libpam-systemd is installed.
A user wishing to access and use a scanner must have permission to access a scanner device file and to use a device on the USB bus. Similar permissions would be required on the USB bus. However, there is little point in doing so unless brian is expected to log in from a remote location with ssh or another remote access program. Prior to buster, putting a user in the scanner group was sufficient to allow scanning as this user. Due to bug , this is not the case anymore. Execute udevadm trigger, or disconnect and reconnect the device, to reload the udev rules.
Configuration Files for libsane libsane-common installs the configuration files dll. Only dll. The content of dll. Commenting out the backends not used might lead to a slight decrease in scanning time. This is often done by software providing a non-SANE backend. Be aware that not all aios support scanning from a computer over USB or the network.
The straightforward way to employ hpaio and hpmud. Having hplip on the system also makes it easier to install a non-free plugin with hp-plugin if the scanner needs one. As a matter of interest, all that is really needed for scanning with an aio scanner is the libsane-hpaio package, installed without its recommended packages, and, if necessary, a way to install a non-free plugin Non-free Scanner Backends Agfa For snapscan scanners, copy the snape Brother 32bit and 64bit Debian packages for scanner devices are usually offered when this search page is used.
You can also access Installation instructions for scanning with a USB or network connection; a udev rule to use with a USB connection is also suggested. It is probably best to conduct a web search for the particular model to locate something suitable. There is iscan-bundle and the newer imagescan-bundle. Which one a user gets depends on the MFD model. Both are. Change to that directory and execute the script with sh install.
The ULD is also used with some Xerox devices. It also has a good deal of information on the installation of the ULD and its interaction with a Debian system. Should the ability of third-party software to initiate scanning be thought to be due to the mislocation of backend files, it is worthwhile considering copying them to a multiarch directory as one way of dealing with the issue.
Frontends for Scanning A frontend is a program that interfaces with a SANE backend to produce a scanned output in a desired format.

The device is controlled via command-line options. After command-line processing, scanimage normally proceeds to acquire an image. So are --mode Gray and --mode Grayscale in use. Please read the backend documentation first.
