NAME
sane - Scanner Access Now Easy: API for accessing scanners
DESCRIPTION
SANE is an application programming interface (API) that provides stan-
dardized 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.
Приложения которые используют SANE интерфейс называются SANE fronted.
A driver that implements the SANE interface is called a SANE backend.
Драйвер, который выполняет интерфейс SANE называется SANE backend.
A meta backend provides some means to manage one or more other back-
ends.
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/local/doc/sane-1.0.18/sane.tex' are references to text files that
were copied to the SANE documentation directory
(/usr/local/doc/sane-1.0.18/) 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/local/doc/sane-1.0.18/.
SANE mailing list
There is a mailing list for the purpose of discussing the SANE stan-
dard 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 prob-
lems, 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 announce-
ments of problems with SANE infrastructure (mailing lists, web
server, etc.).
Compiling and installing SANE
Look at /usr/local/doc/sane-1.0.18/README and the os-dependent README
files for information about compiling and installing SANE.
SCSI configuration

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 pri-
marily 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 sys-
tems. See sane-pint(5).
test
The SANE test backend is for testing frontends and the SANE installa-
tion. 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/local/doc/sane-1.0.18/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/local/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/doc/sane-1.0.18/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/local/doc/sane-1.0.18/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/doc/sane-1.0.18/PROJECTS for
projects that are planned or not yet included into the SANE distribu-
tion 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 scan-
ner: 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 scan-
ners, 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.
ПРАВА не только для ROOT!
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 back-
end'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 back-
end's name is mentioned in /usr/local/etc/sane.d/dll.conf. Some back-
ends 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 cor-
rectly without the intervention of the administrator. Also on some
operating systems auto-detection may not work. Check the backend's man-
ual page for details. - См. страницу с драйвером для деталей.
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, con-
tact 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: scan-
image >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.
HOW CAN YOU HELP SANE
