sane-hp3900(5)            SANE Scanner Access Now Easy            sane-hp3900(5)




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 sane-hp3900(5) 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(1) 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

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

       /opt/local/lib/sane/libsane-hp3900.a
              The static library implementing this backend.

       /opt/local/lib/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.  On *NIX systems, 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
              /opt/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
              directories.  For example, setting SANE_CONFIG_DIR to
              "/tmp/config:" would result in directories tmp/config, ., and
              /opt/local/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.
