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.

OTHER PLUSTEK SCANNERS

       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.

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.
