sane(7) SANE Scanner Access Now Easy sane(7) NAME sane - Scanner Access Now Easy: API for accessing scanners DESCRIPTION SANE is an application programming interface (API) that provides standard- ized access to any raster image scanner hardware. The standardized inter- face makes it possible to write just one driver for each scanner device in- stead of one driver for each scanner and application. While SANE is primarily targeted at a UNIX environment, the standard has been carefully designed to make it possible to implement the API on virtu- ally any hardware or operating system. This manual page provides a summary of the information available about SANE. If you have trouble getting your scanner detected, read the PROBLEMS sec- tion. TERMINOLOGY An application that uses the SANE interface is called a SANE frontend. A driver that implements the SANE interface is called a SANE backend. A meta backend provides some means to manage one or more other backends. SOFTWARE PACKAGES The package `sane-backends' contains a lot of backends, documentation (in- cluding the SANE standard), networking support, and the command line fron- tend `scanimage'. The frontends `xscanimage', `xcam', and `scanadf' are included in the package `sane-frontends'. Both packages can be downloaded from the SANE homepage (http://www.sane-project.org/). Information about other frontends and backends can also be found on the SANE homepage. GENERAL INFORMATION The following sections provide short descriptions and links to more infor- mation about several aspects of SANE. A name with a number in parenthesis (e.g. `sane-dll(5)') points to a manual page. In this case `man 5 sane-dll' will display the page. Entries like `/usr/local/share/doc/sane- backends/sane.tex' are references to text files that were copied to the SANE documentation directory (/usr/local/share/doc/sane-backends/) during installation. Everything else is a URL to a resource on the web. SANE homepage Information on all aspects of SANE including a tutorial and a link to the SANE FAQ can be found on the SANE homepage: http://www.sane-project.org/. SANE device lists The SANE device lists contain information about the status of SANE sup- port for a specific device. If your scanner is not listed there (either supported or unsupported), please contact us. See section HOW CAN YOU HELP SANE for details. There are lists for specific releases of SANE, for the current development version and a search engine: http://www.sane-project.org/sane-supported-devices.html. The lists are also installed on your system at /usr/local/share/doc/sane-backends/. SANE mailing list There is a mailing list for the purpose of discussing the SANE standard and its implementations: sane-devel. Despite its name, the list is not only intended for developers, but also for users. There are also some more lists for special topics, however, for users, sane-devel is the right list. How to subscribe and unsubscribe: http://www.sane-project.org/mailing-lists.html. SANE IRC channel The IRC (Internet Relay Chat) channel #sane can be found on the Freenode network (irc.freenode.net). It's for discussing SANE problems, talking about development and general SANE related chatting. Before asking for help, please read the other documentation mentioned in this manual page. The channel's topic is also used for announcements of problems with SANE infrastructure (mailing lists, web server, etc.). Compiling and installing SANE Look at /usr/local/share/doc/sane-backends/README and the os-dependent README files for information about compiling and installing SANE.

See sane-pint(5). test The SANE test backend is for testing frontends and the SANE installation. It provides test pictures and various test options. See sane-test(5). v4l The sane-v4l library implements a SANE backend that provides generic ac- cess to video cameras and similar equipment using the V4L (Video for Linux) API. See sane-v4l(5). Also, have a look at the backend information page at http://www.sane-project.org/sane-supported-devices.html and the list of projects in /usr/local/share/doc/sane-backends/PROJECTS. CHANGING THE TOP-LEVEL BACKEND By default, all SANE backends (drivers) are loaded dynamically by the sane-dll meta backend. If you have any questions about the dynamic loading, read sane-dll(5). SANE frontend can also be linked to other backends di- rectly by copying or linking a backend to libsane.so in /usr/lo- cal/lib/sane. DEVELOPER'S DOCUMENTATION It's not hard to write a SANE backend. It can take some time, however. You should have basic knowledge of C and enough patience to work through the documentation and find out how your scanner works. Appended is a list of some documents that help to write backends and frontends. The SANE standard defines the application programming interface (API) that is used to communicate between frontends and backends. It can be found at /usr/local/share/doc/sane-backends/sane.ps (if latex is installed on your system) and on the SANE website: http://www.sane-project.org/html/ (HTML), or http://www.sane-project.org/sane.ps (Postscript). There is some more information for programmers in /usr/lo- cal/share/doc/sane-backends/backend-writing.txt. Most of the internal SANE routines (sanei) are documented using doxygen: http://www.sane-project.org/sanei/. Before a new backend or frontend project is started, have a look at /usr/local/share/doc/sane-back- ends/PROJECTS for projects that are planned or not yet included into the SANE distribution and at our bug-tracking system: http://www.http://www.sane-project.org/bugs.html. There are some links on how to find out about the protocol of a scanner: http://www.meier-geinitz.de/sane/misc/develop.html. If you start writing a backend or frontend or any other part of SANE, please contact the sane-devel mailing list for coordination so the same work isn't done twice. FILES /usr/local/etc/sane.d/*.conf The backend configuration files. /usr/local/lib/sane/libsane-*.a The static libraries implementing the backends. /usr/local/lib/sane/libsane-*.so The shared libraries implementing the backends (present on systems that support dynamic loading). /usr/local/share/doc/sane-backends/* SANE documentation: The standard, READMEs, text files for backends etc. PROBLEMS If your device isn't found but you know that it is supported, make sure that it is detected by your operating system. For SCSI and USB scanners, use the sane-find-scanner tool (see sane-find-scanner(1) for details). It prints one line for each scanner it has detected and some comments (#). If sane-find-scanner finds your scanner only as root but not as normal user, the permissions for the device files are not adjusted correctly. If the scanner isn't found at all, the operating system hasn't detected it and may need some help. Depending on the type of your scanner, read sane-usb(5) or sane-scsi(5). If your scanner (or other device) is not connected over the SCSI bus or USB, read the backend's manual page for details on how to set it up. Now your scanner is detected by the operating system but not by SANE? Try scanimage -L. If the scanner is not found, check that the backend's name is mentioned in /usr/local/etc/sane.d/dll.conf. Some backends are com- mented out by default. Remove the comment sign for your backend in this case. Also some backends aren't compiled at all if one of their prerequi- sites are missing. Examples include dc210, dc240, canon_pp, hpsj5s, gphoto2, pint, qcam, v4l, net, sm3600, snapscan, pnm. If you need one of these backends and they aren't available, read the build instructions in the README file and the individual manual pages of the backends. Another reason for not being detected by scanimage -L may be a missing or wrong configuration in the backend's configuration file. While SANE tries to automatically find most scanners, some can't be setup correctly without the intervention of the administrator. Also on some operating systems auto- detection may not work. Check the backend's manual page for details. If your scanner is still not found, try setting the various environment variables that are available to assist in debugging. The environment vari- ables are documented in the relevant manual pages. For example, to get the maximum amount of debug information when testing a Mustek SCSI scanner, set environment variables SANE_DEBUG_DLL, SANE_DEBUG_MUSTEK, and SANE_DE- BUG_SANEI_SCSI to 128 and then invoke scanimage -L . The debug messages for the dll backend tell if the mustek backend was found and loaded at all. The mustek messages explain what the mustek backend is doing while the SCSI debugging shows the low level handling. If you can't find out what's going on by checking the messages carefully, contact the sane-devel mailing list for help (see REPORTING BUGS below). Now that your scanner is found by scanimage -L, try to do a scan: scanimage >image.pnm. This command starts a scan for the default scanner with de- fault settings. All the available options are listed by running scanimage --help. If scanning aborts with an error message, turn on debugging as mentioned above. Maybe the configuration file needs some tuning, e.g. to setup the path to a firmware that is needed by some scanners. See the back- end's manual page for details. If you can't find out what's wrong, contact sane-devel. To check that the SANE libraries are installed correctly you can use the test backend, even if you don't have a scanner or other SANE device: scanimage -d test -T You should get a list of PASSed tests. You can do the same with your back- end by changing "test" to your backend's name. So now scanning with scanimage works and you want to use one of the graphi- cal frontends like xsane, xscanimage, or quiteinsane but those frontends don't detect your scanner? One reason may be that you installed two ver- sions of SANE. E.g. the version that was installed by your distribution in /usr and one you installed from source in /usr/local/. Make sure that only one version is installed. Another possible reason is, that your system's dynamic loader can't find the SANE libraries. For Linux, make sure that /etc/ld.so.conf contains /usr/local/lib and does not contain /usr/lo- cal/lib/sane. See also the documentation of the frontends.
