          sane-sm3840 - SANE backend for Microtek scanners with SCAN08
          USB chip

          The sane-sm3840 library implements a SANE (Scanner Access
          Now Easy) backend that provides access to some Microtek
          scanners with the SCAN08 USB chip.

          There exist backends for Microtek scanners with SCSI command
          set.  Refer to sane-microtek(5) and sane-microtek2(5) for

          There also exists a Microtek 3600 series driver, see
          sane-sm3600(5) for details.

          At present, the following scanners are known positively to
          work with this backend:

               Vendor     Product ID:     Remark:
               --------   --------------  -----------
               Microtek   ScanMaker 3840  All modes OK
               Microtek   ScanMaker 4800  All modes OK

          If you own a Microtek scanner with the SCAN08 chip other
          than the ones listed above, it may or may not work with
          SANE.  Feel free to contact the backend author
          ( to report results with scanners not on
          the list.

          The following options are supported by the sane-sm3840

          --mode color|gray|lineart|halftone
               Color or grayscale mode.

          --resolution 150|300|600|1200
               Pixels per inch for scans.

          --depth 8|16
               Note that the least significant bits of 16bpp mode may
               be noise.

          --brightness 1..4096

               Higher numbers increase brightness of returned image.

          --contrast 0.1..9.9
               Larger numbers decrease contrast of returned image.

          --lamp-timeout 1..15
               Time in minutes until the lamp is turned off after a

               on systems that support dynamic loading).

               If the library was compiled with debug support enabled,
               this environment variable controls the debug level for
               this backend.  E.g., a value of 128 requests all debug
               output to be printed.  Smaller levels reduce verbosity.
               To see error messages on stderr set SANE_DEBUG_SM3840
               to 1.
