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 /sane/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

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

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

/sane/lib/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 /sane/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 "/sane/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
Man page doesn't provide much information yet.
