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  ig-
       nored.	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/lo-
	      cal/etc/sane.d.	If  the	value of the environment variable ends
	      with the directory separator character, then the default	direc-
	      tories  are searched after the explicitly	specified directories.
	      For example, setting SANE_CONFIG_DIR to "/tmp/config:" would re-
	      sult   in	  directories	"tmp/config",	".",   and   "/usr/lo-
	      cal/etc/sane.d" being searched (in this order).

       SANE_DEBUG_HP5400
	      If the library was compiled with debug support enabled, this en-
	      vironment	 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.
