NAME

       sane - Scanner Access Now Easy: API for accessing scanners

DESCRIPTION

       SANE  is  an  application programming interface (API) that provides standardized access to
       any raster image scanner hardware. The standardized interface makes it possible  to  write
       just  one  driver  for  each  scanner  device  instead  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 virtually 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 section.

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 (including the  SANE
       standard),  networking  support, and the command line frontend `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 information 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/share/doc/libsane/sane.tex' are references to text files that were copied to the
SANE documentation directory (/usr/share/doc/libsane/) 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 support 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/share/doc/libsane/.

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/share/doc/libsane/README and the os-dependent README files for information
about compiling and installing SANE.

SCSI configuration
For information about various systems and SCSI controllers see sane-scsi(5).

USB configuration
For information about USB configuration see sane-usb(5).

       /usr/share/doc/libsane/PROJECTS.

MISCELLANEOUS BACKENDS

       dll
         The  sane-dll  library  implements  a  SANE backend that provides access to an arbitrary
         number of other SANE backends by dynamic loading. See sane-dll(5).

       net
         The SANE network daemon saned provides access to scanners located on different computers
         in connection with the net backend. See sane-net(5) and saned(8).

       pnm
         PNM  image  reader  pseudo-backend.  The  purpose of this backend is primarily to aid in
         debugging of SANE frontends. See sane-pnm(5).

       pint
         Backend for scanners that use the PINT (Pint Is Not  Twain)  device  driver.   The  PINT
         driver is being actively developed on the OpenBSD platform, and has been ported to a few
         other *nix-like operating systems. 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 access 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/share/doc/libsane/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 directly by copying or linking a backend  to
       libsane.so in /usr/lib/arch_triplet/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/share/doc/libsane/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/share/doc/libsane/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/share/doc/libsane/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.

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
/etc/sane.d/dll.conf. Some backends are commented 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
prerequisites 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 variables 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_DEBUG_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 default 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
backend'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 backend by changing
"test" to your backend's name.

So now scanning with scanimage works and you want to use one of the graphical frontends
like xsane, xscanimage, or quiteinsane but those frontends don't detect your scanner? One
reason may be that you installed two versions 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/local/lib/sane. See
also the documentation of the frontends.
