sane-hp5400(5)           SANE Scanner Access Now Easy           sane-hp5400(5)



NAME
       sane-hp5400 - SANE backend for Hewlett-Packard 54XX scanners

DESCRIPTION
       The sane-hp5400 library implements a SANE (Scanner Access Now Easy)
       backend that provides access to the following Hewlett-Packard USB
       flatbed scanners:

              ScanJet 5400C
              ScanJet 5470C
              ScanJet 5490C

       More details can be found on the hp5400 backend homepage
       http://hp5400backend.sourceforge.net/.

       This is ALPHA software. Keep your hand at the scanner's plug and unplug
       it, if the head bumps at the end of the scan area. See also the BUGS
       section.

       If you own a scanner other than the ones listed above that works with
       this backend, please let us know this by sending the scanner's exact
       model name and the USB vendor and device ids (e.g. from
       /proc/bus/usb/devices, sane-find-scanner or syslog) to us. Even if the
       scanner's name is only slightly different from the models mentioned
       above, please let us know.

CONFIGURATION
       The contents of the hp5400.conf file is a list of usb lines containing
       vendor and product ids that correspond to USB scanners. The file can
       also contain the names of device files that correspond to an HP 54XX
       scanner.  Empty lines and lines starting with a hash mark (#) are
       ignored.  The scanners are autodetected by usb vendor_id product_id
       statements which are already included into hp5400.conf.  "vendor_id"
       and "product_id" are hexadecimal numbers that identify the scanner. If
       autodetection does not work, add the device name of your scanner to the
       configuration file, e.g.  /dev/usb/scanner0.

FILES
       /etc/sane.d/hp5400.conf
              The backend configuration file (see also description of
              SANE_CONFIG_DIR below).

       /usr/local/lib/sane/libsane-hp5400.a
              The static library implementing this backend.

       /usr/local/lib/sane/libsane-hp5400.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_HP5400
              If the library was compiled with debug support enabled, this
              environment variable controls the debug level for this backend.
              Higher debug levels increase the verbosity of the output.

              Example: export SANE_DEBUG_HP5400=4

BUGS
       Scanning is only tested with Linux/ix86/gcc. Be careful when testing on
       other operating systems and especially on big-endian platforms. The
       scanner may get wrong data.
