sane-plustek(5)		 SANE Scanner Access Now Easy	       sane-plustek(5)

       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(5) 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.

       The  SCSI scanner OpticPro 19200S is a rebadged Artec AM12S scanner and
       is supported by the sane-artec(5) 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 /usr/local/etc/sane.d/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 negative	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 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 off-
	      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(1) to check that you have  ac-
       cess 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.  On *NIX systems, the	direc-
	      tories are separated by a	colon (`:'), under OS/2, they are sep-
	      arated  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 /usr/lo-
	      cal/etc/sane.d.  If the value of the environment	variable  ends
	      with  the	directory separator character, then the	default	direc-
	      tories are searched after	the explicitly specified  directories.
	      For example, setting SANE_CONFIG_DIR to "/tmp/config:" would re-
	      sult in directories tmp/config, ., and /usr/local/etc/sane.d be-
	      ing searched (in this order).

	      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.

	      Example: export SANE_DEBUG_PLUSTEK=10

       sane(7),	 sane-usb(5),  sane-u12(5),  sane-gt68xx(5),  sane-stek_pp(5),
       sane-find-scanner(1), scanimage(1)

       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(1)),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.
