          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 scan-
          ners 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(5) backend.

          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 cur-
          rently reported to work. If your Plustek scanner has another
          Product ID, then the device is NOT supported by this back-

          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 /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

          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

          option mov m
               m is the model override switch. It works only with

               using the dark calibration strip of the scanner. If the

               is to switch off the lamp during this step.

               and offset values of the AFE for each channel. The
               range is between 0 and 63. -1 means autocalibration.

          You have to make sure, that the USB subsystem is loaded cor-
          rectly and you have access to the device-node. For more
          details see sane-usb(5) manpage. You might use

               The shared library implementing this backend (present
               on systems that support dynamic loading).

               This environment variable specifies the list of direc-
               tories 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 direc-
               tory separator character, then the default directories
               are searched after the explicitly specified directo-
               ries.  For example, setting SANE_CONFIG_DIR to
               "/tmp/config:" would result in directories tmp/config,
               ., and /etc/sane.d being searched (in this order).

               If the library was compiled with debug support enabled,
               this environment variable controls the debug level for
               this backend.  Higher debug levels increase the ver-
               bosity of the output.

               Example: export SANE_DEBUG_PLUSTEK=10

          sane(7), sane-usb(5), sane-u12(5), sane-gt68xx(5),

          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 values greater than 24 force the backend to out-
          put 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.

          * 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 com-
          pare the product-id to the one your device has.

          * Negative/Slide scanning quality is poor.
