sane-hp3900


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://source-
       forge.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).

              "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.
