NAME

   sane-hp3900 - SANE backend for RTS8822 chipset based scanners

DESCRIPTION

   The  sane-hp3900  library  implements  a SANE (Scanner Access Now Easy)
   backend that provides access at least  to  the  following  USB  flatbed
   scanners:

          Model:                     Chipset:
          ------                     --------
          HP ScanJet 3800            RTS8822BL-03A
          HP ScanJet 3970            RTS8822L-01H
          HP ScanJet 4070 Photosmart RTS8822L-01H
          HP ScanJet 4370            RTS8822L-02A
          HP ScanJet G2710           RTS8822BL-03A
          HP ScanJet G3010           RTS8822L-02A
          HP ScanJet G3110           RTS8822L-02A
          UMAX Astra 4900/4950       RTS8822L-01H *
          BenQ 5550                  RTS8823L-01E *

   More   details   can   be   found   on   the  hp3900  backend  homepage
   http://sourceforge.net/projects/hp3900-series/.

   This is ALPHA software. Keep your hand at the scanner's plug and unplug
   it, if scanner does not start to scan. 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 hp3900.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  39XX
   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 hp3900.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,

FILES

   /etc/sane.d/hp3900.conf
          The  backend  configuration  file  (see  also   description   of
          SANE_CONFIG_DIR below).

   /usr/lib/arch_triplet/sane/libsane-hp3900.a
          The static library implementing this backend.

   /usr/lib/arch_triplet/sane/libsane-hp3900.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
          /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  directories.   For
          example,  setting SANE_CONFIG_DIR to "/tmp/config:" would result
          in  directories  "tmp/config",  ".",  and  "/etc/sane.d"   being
          searched (in this order).

   SANE_DEBUG_HP3900
          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_HP3900=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.
