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 availaby 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  coarse calibration results, 1 --> save
              results of coarse 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 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 theres 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 theres 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/sane/libsane-plustek.a
              The static library implementing this backend.

       /usr/lib/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 CDD-sensor and the  stepper  motor  i.e.
       you  have  a 600x1200 dpi scanner and you are scanning using 800dpi, so
       scaling is necesary, because the sensor only delivers  600dpi  but  the
       motor is capable to perform 1200dpi steps.

       *  Plusteks’  model  policy  is somewhat inconsistent. This means, they
       sell technical 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.
