    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

           /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.
