NAME

       sane-snapscan - SANE backend for AGFA SnapScan flatbed scanners

DESCRIPTION

       The  sane-snapscan  library  implements  a  SANE  (Scanner  Access  Now Easy) backend that
       provides access to AGFA SnapScan flatbed scanners. At present, the following scanners  are
       supported  from  this  backend: AGFA SnapScan 300, 310, 600, and 1236s, 1236u, 1212u, e20,
       e25, e40, e50, e60, Vuego 310s, Acer 300f, 310s, 610s, 610plus, Prisa  620s,  Prisa  620u,
       Prisa  620ut,  Prisa 640u, Prisa 640bu, Prisa 1240, Prisa 3300, Prisa 4300, Prisa 5300 and
       Guillemot Maxi Scan A4 Deluxe (SCSI) (with varying success).

DEVICE NAMES

       This backend expects device names of the form:

              special

       Where special is the path-name for the special device that corresponds to a SCSI  scanner.
       For  SCSI  scanners, the special device name must be a generic SCSI device or a symlink to
       such a device.  Under Linux, such a  device  name  could  be  /dev/sga  or  /dev/sge,  for
       example.  See sane-scsi(5) for details.

       For  USB  scanners the devicename must contain the keyword "usb", as in /dev/usbscanner or
       /dev/usb/scanner0.  For scanners that need a firmware upload before scanning  add  a  line
       starting with "firmware" followed by the fully qualified path to your firmware file, e.g.

              firmware /usr/share/sane/snapscan/firmware.bin

       For further details read http://snapscan.sourceforge.net.

CONFIGURATION

       The  contents  of  the  snapscan.conf  file  is  a list of device names that correspond to
       SnapScan scanners.  Empty lines and lines starting with a hash mark (#) are ignored.   See
       sane-scsi(5) on details of what constitutes a valid device name.

FILES

       /etc/sane.d/snapscan.conf
              The backend configuration file (see also description of SANE_CONFIG_DIR below).

       /usr/lib/arch_triplet/sane/libsane-snapscan.a
              The static library implementing this backend.

       /usr/lib/arch_triplet/sane/libsane-snapscan.so
              The  shared  library  implementing  this  backend  (present on systems that support
              dynamic loading).

ENVIRONMENT

       SANE_CONFIG_DIR
              This environment variable specifies the list of directories that  may  contain  the
              configuration  file.   Under  UNIX, the directories are separated by a colon (`:'),
              under OS/2, they are separated by a semi-colon (`;').  If this variable is not set,
              the  configuration  file is searched in two default directories: first, the current
              working directory (".") and then in /etc/sane.d.  If the value of  the  environment
              variable  ends with the directory separator character, then the default directories
              are searched after the explicitly  specified  directories.   For  example,  setting
              SANE_CONFIG_DIR  to  "/tmp/config:"  would result in directories "tmp/config", ".",
              and "/etc/sane.d" being searched (in this order).

       SANE_DEBUG_SNAPSCAN
              If the library was compiled with debug support enabled, this  environment  variable
              controls the debug level for this backend.  E.g., a value of 255 requests all debug
              output to be printed.  Smaller levels reduce verbosity.

BUGS
