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
       /usr/local/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 config‐
	      uration  file is searched in two default directories: first, the
	      current	 working    directory	 (".")	   and	   then	    in
	      /usr/local/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 directo‐
	      ries.  For example, setting  SANE_CONFIG_DIR  to	"/tmp/config:"
	      would    result	 in   directories   "tmp/config",   ".",   and
	      "/usr/local/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.
