SANE Scanner Access Now Easy                      sane-avision(5)



NAME
     sane-avision - SANE backend for original Avision and Avision
     OEM  scanners  (HP,  Minolta,  Mitsubishi, UMAX and possibly
     more) flatbed and film scanners.


ABOUT THIS FILE
     This file is a  short  descripton  for  the  avision-backend
     shipped with SANE.


DESCRIPTION
     The sane-avision library implements a SANE  (Scanner  Access
     Now  Easy)  backend  that provides access to various Avision
     scanners and  the  Avision  OEM  scanners  labelled  by  HP,
     Minolta, Mitsubishi or Fujitsu.

     It is fully big-endian aware and in every-day use on PowerPC
     and SPARC systems.

     I suggest you hold one hand you try the first scans -  espe-
     cially with film-scanners!


CONFIGURATION
     The  configuration  file  for  this   backend   resides   in
     /etc/sane.d/avision.conf.

     Its contents is a list of device names  that  correspond  to
     Avision and Avision compatible scanners and backend-options.
     Empty lines and lines starting with  a  hash  mark  (#)  are
     ignored. A sample configuration file is shown below:

      # this is a comment

      option force-a4
      option force-a3
      option disable-gamma-table
      option disable-calibration

      #scsi Vendor Model Type Bus Channel ID LUN
      scsi AVISION
      scsi HP
      scsi /dev/scanner
      usb 0x03f0 0x0701


     force-a4:
          Forces the  backend  to  overwrite  the  scanable  area
          returned  by  the  scanner  to ISO A4. Scanner that are
          known to return bogus data are marked in the backend so
          if  you  need  this  option  please  report this to the

          backend maintainer. USE WITH CARE!

     force-a3:
          Forces the  backend  to  overwrite  the  scanable  area
          returned  by  the  scanner  to ISO A3. Scanner that are
          known to return bogus data are marked in the backend so
          if you need this option please report this to the back-
          end maintainer. USE WITH CARE!

     disable-gamma-table:
          Disables the usage of the  scanner's  gamma-table.  You
          might try this if your scans hang or only produces ran-
          dom garbage.

     disable-calibration:
          Disables the scanner's color calibration. You might try
          this  if  your  scans hang or only produces random gar-
          bage.

     Note:
          Any option above modifies  the  default  code-flow  for
          your  scanner. The options should only be used when you
          encounter problems with the default be- haviour of  the
          backend.  Please  report  the  need  of  options to the
          backend-author so the backend can be fixed as  soon  as
          possible.


DEVICE NAMES
     This backend expects device names of the form:

          scsi scsi-spec

          usb usb-spec

     Where scsi-spec is the path-name to a special  device  or  a
     device ID for the device that corresponds to a SCSI scanner.
     The special device name must be a generic SCSI device  or  a
     symlink to such a device, for example on Linux "/dev/sga" or
     "/dev/sg0". The device ID is the ID returned by the scanner,
     for example "HP" or "AVISION". See sane-scsi(5) for details.

     Note:
          Since the backend now includes native USB access, it is
          no longer needed - even considered obsolete - to access
          USB scanner via the SCSI emulation (named hpusbscsi  on
          Linux)  for Avision USB devices such as the HP 53xx, HP
          74xx or Minolta film-scanners.

     usb-spec is the USB device name, the vendor/product ID  pair
     or the name used by libusb corresponding to the USB scanner.
     For example "0x03f0 0x0701" or "libusb:002:003".  See  sane-

     usb(5) for details.

     The program sane-find-scanner helps to find out the  correct
     scsi or usb device name.

     A list with supported devices  is  built  into  the  avision
     backend  so  normally  specifying an ID should not be neces-
     sary.


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

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

     /usr/lib/sane/libsane-avision.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  direc-
          tories  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  direc-
          tories  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_AVISION
          If the library was compiled with debug support enabled,
          this  environment variable controls the debug level for
          this backend.  Higher debug levels increase the verbos-
          ity  of  the  output. The debug level 7 is the author's
          prefered value to debug backend problems.

          Example: export SANE_DEBUG_AVISION=7
