NAME

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

DESCRIPTION

       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.

SUPPORTED DEVICES

       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.

       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.

CONFIGURATION

       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 mode

       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 only)

       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.

       Note:
       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.

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

FILES

       /etc/sane.d/plustek.conf
              The backend configuration file

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

       /usr/lib/arch_triplet/sane/libsane-plustek.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.   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).

       SANE_DEBUG_PLUSTEK
              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

CONTACT AND BUG-REPORTS

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

       Additional info and hints can be obtained from our
       Mailing-List archive at:
       http://www.sane-project.org/mailing-lists.html

       or directly from the projects' homepage at:
       http://www.gjaeger.de/scanner/plustek/

       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.

KNOWN BUGS & RESTRICTIONS

       *  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.
