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

       @CONFIGDIR@/hp5400.conf
              The backend configuration file (see also description of SANE_CONFIG_DIR below).

       @LIBDIR@/libsane-hp5400.a
              The static library implementing this backend.

       @LIBDIR@/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 @CONFIGDIR@.  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 "@CONFIGDIR@" 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.
