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


       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

       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

       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(1)  or syslog) to us. Even if
       the scanner's name is only slightly different from the models mentioned
       above, please let us know.


       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.


              The   backend   configuration  file  (see  also  description  of
              SANE_CONFIG_DIR below).

              The shared library implementing this backend (present on systems
              that support dynamic loading).


              This environment variable specifies the list of directories that
              may contain the configuration file.  On *NIX systems, the direc-
              tories are separated by a colon (`:'), under OS/2, they are sep-
              arated 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  /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/local/etc/sane.d be-
              ing searched (in this order).

              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


       sane(7), sane-usb(5), sane-find-scanner(1),

       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.
