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  backends,  documentation, networking support, and the command line
       frontend scanimage(1).  The frontends xscanimage(1), xcam(1), and scanadf(1) 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/README 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.libera.chat).
         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.

       /usr/share/doc/libsane/PROJECTS.

MISCELLANEOUS BACKENDS

       dll
         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(8)  provides  access  to  scanners  located  on  different  computers  in
         connection with the sane-net(5) backend. See 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
         Supports 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
         Tests frontends and the SANE installation.  It provides test pictures and  various  test  options.  See
         sane-test(5).

       v4l
         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 frontends can also be  linked  to  other
       backends directly by copying or linking a backend to libsane.so in /usr/lib/x86_64-linux-gnu/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 http://sane-project.gitlab.io/standard/ .

       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 that work is not duplicated.

FILES

       /etc/sane.d/*.conf
              The backend configuration files.

       /usr/lib/x86_64-linux-gnu/sane/libsane-*.a
              The static libraries implementing the backends.

       /usr/lib/x86_64-linux-gnu/sane/libsane-*.so
              The shared libraries implementing the backends (present on systems that support dynamic loading).

       /usr/share/doc/libsane/*
              SANE documentation: The 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(1) utility.  It prints one line
       for each scanner it has detected and some comments (#).  If sane-find-scanner(1) 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.

       Is your scanner 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 it isn'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 incorrect 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 SANE_DEBUG_DLL messages tell if the sane-mustek(5) backend was  found  and  loaded  at
       all. The SANE_DEBUG_MUSTEK messages explain what the backend is doing while the SANE_DEBUG_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  (1)  works  and  you  want to use one of the graphical frontends like
       xsane(1), xscanimage(1), or quiteinsane (1) 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.
