sane-plustek - SANE backend for LM983[1/2/3] based USB flatbed scanners


   The  sane-plustek  library  implements a SANE (Scanner Access Now Easy)
   backend that provides access to USB flatbed scanners based on  National
   Semiconductor  Merlin  chipsets  (LM9831,  9832  and  9833).  If you're
   looking for parallel-port support for Plustek scanner please  refer  to
   the sane-plustek_pp backend.


   The  Backend  is  able  to  support  USB  scanner based on the National
   Semiconductor chipsets LM9831, LM9832 and LM9833. The following  tables
   show  various  devices  which  are  currently reported to work. If your
   Plustek scanner  has  another  Product  ID,  then  the  device  is  NOT
   supported by this backend.

   For parallelport device support see the plustek_pp backend.
   The  SCSI scanner OpticPro 19200S is a rebadged Artec AM12S scanner and
   is supported by the Artec backend.
   Only the National Semiconductor LM983[1/2/] based  devices  of  Plustek
   are supported by this backend. Older versions of the U12, the UT12, the
   U1212 and U1248 (GrandTech chipset) are not supported.

   To use your scanner with this backend, you need at least two entries in
   the configuration file /etc/sane.d/plustek.conf
          [usb] vendor-id product-id
          device /dev/usbscanner

   [usb]  tells  the  backend,  that  the   following   devicename   (here
   /dev/usbscanner)  has  to  be  interpreted  as  USB  scanner device. If
   vendor- and product-id has not been specified,  the  backend  tries  to
   detect this by its own. If device is set to auto then the next matching
   device is used.
   The following options can be used for a default setup of  your  device.
   Most of them are also available through the frontend.

   The Options:

   option warmup t
          t  specifies  the  warmup  period  in seconds, if set to -1, the
          automatic warmup function will be used

   option lampOff t
          t is the time in seconds for switching off the lamps in  standby

   option lOffonEnd b
          b specifies the behaviour when closing the backend, 1 --> switch
          lamps off, 0 --> do not change lamp status

   option mov m
          m is the model  override  switch.  It  works  only  with  Mustek
          BearPaw devices.
          m/PID |    0x1000    |    0x1001
            0   | BearPaw 1200 | BearPaw 2400
            1   |  no function | BearPaw 1200

   option invertNegatives b
          b 0 --> do not invert the picture during negativ scans,
          1 --> invert picture

   option cacheCalData b
          b 0 --> do not save calibration results,
          1 --> save results of calibration in ~/.sane/ directory

   option altCalibration b
          b 0 --> use standard calibration routines,
          1  -->  use  alternate  calibration  (only  non Plustek devices,
          standard for CIS devices)

   option skipFine b
          b 0 --> perform fine calibration,
          1 --> skip fine calibration (only non Plustek devices)

   option skipFineWhite b
          b 0 --> perform white fine calibration,
          1 --> skip white fine calibration (only non Plustek devices)

   option skipDarkStrip b
          b 0 --> perform dark calibration, with enabled  lamp  using  the
          dark  calibration  strip of the scanner. If the scanner does not
          have such a strip, the alternative way is to switch off the lamp
          during this step.
          1  -->  always  switch off the lamp for dark calibration, even a
          black strip is available

   option skipCalibration b
          b 0 --> perform calibration,
          1 --> skip calibration (only non Plustek devices)

   option enableTPA b
          b 0 --> default behaviour, specified by the internal tables,
          1 --> override internal tables and allow  TPA  mode  (EPSON/UMAX

   option posOffX x
   option posOffY y
   option tpaOffX x
   option tpaOffY y
   option negOffX x
   option negOffY y
          x  y By using this settings, the user can adjust the given image
          positions.  Please note, that there's no internal range checking
          for this feature.

   option posShadingY p
   option tpaShadingY p
   option negShadingY p
          p  overrides  the  internal  shading position. The values are in
          steps.  Please note, that there's no internal range checking for
          this feature.

   option redGamma r
   option greenGamma g
   option blueGamma b
   option grayGamma gr
          r g b gr
   By using these values, the internal linear gamma table (r,g,b,gr = 1.0)
   can be adjusted.

   option red_gain r
   option red_offset ro
   option green_gain g
   option green_offset go
   option blue_gain b
   option blue_offset bo
          r g b ro go bo These values can be used  to  set  the  gain  and
          offset  values of the AFE for each channel. The range is between
          0 and 63. -1 means autocalibration.

   See the plustek.conf file for examples.

   You have to make sure, that the USB subsystem is loaded  correctly  and
   you  have  access to the device-node. For more details see sane-usb (5)
   manpage. You might use sane-find-scanner to check that you have  access
   to your device.

   If there's no configuration file, the backend defaults to device auto


          The backend configuration file

          The static library implementing this backend.

          The shared library implementing this backend (present on systems
          that support dynamic loading).


          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).

          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_PLUSTEK=10


   sane(7), sane-usb(5), sane-u12(5), sane-gt68xx(5),


   Please send any information and bug-reports to:
   SANE Mailing List

   Additional info and hints can be obtained from our
   Mailing-List archive at:

   or directly from the projects' homepage at:

   To  obtain debug messages from the backend, please set the environment-
   variable SANE_DEBUG_PLUSTEK before calling your favorite  scan-frontend
   (i.e. xscanimage).
   i.e.: export SANE_DEBUG_PLUSTEK=20 ; xscanimage

   The  value  controls  the  verbosity  of the backend. Please note, that
   values greater than 24 force the backend  to  output  raw  data  files,
   which  could be rather large. The ending of these files is ".raw".  For
   problem reports it should be enough the set the verbosity to 13.


   * The driver does not support these manic scalings up to 16  times  the
   physical  resolution.  The  only scaling is done on resolutions between
   the physical resolution of the CCD-/CIS-sensor and  the  stepper  motor
   i.e. you have a 600x1200 dpi scanner and you are scanning using 800dpi,
   so scaling is necessary, because the sensor only  delivers  600dpi  but
   the motor is capable to perform 1200dpi steps.

   *   Plusteks'   model   policy  is  somewhat  inconsistent.  They  sell
   technically different devices under the same product name. Therefore it
   is  possible that some devices like the UT12 or U12 won't work - please
   check the model list above and compare the product-id to the  one  your
   device has.

   * Negative/Slide scanning quality is poor.
