       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 look-
       ing 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 Semi-
       conductor 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.

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

       [usb] tells the backend, that the following devicename (here  /dev/usb-
       scanner)  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
       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 au-
              tomatic 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, stan-
              dard 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 posShadingY p
       option tpaShadingY p
       option negShadingY p
              p  overrides  the  internal  shading position. The values are in

              this feature.

       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.

              set  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.

              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 config-
              uration file is searched in two default directories: first,  the
              current working directory (".") and then in @CONFIGDIR@.  If the
              value of the environment variable ends with the directory  sepa-
              rator 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 "@CONFIGDIR@" being searched (in this or-

              If the library was compiled with debug support enabled, this en-
              vironment variable controls the debug level  for  this  backend.
              Higher debug levels increase the verbosity of the output.

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

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

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

       The value controls the verbosity of the backend. Please note, that val-
       ues greater than 24 force the backend to output raw data  files,  which
       could  be rather large. The ending of these files is ".raw".  For prob-
       lem 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 techni-
       cally 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.
