NAME

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

DESCRIPTION

   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 details.

   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 (earle@ziplabel.com) to report results with scanners
   not on the list.

FRONTEND OPTIONS

   The following options are supported by the sm3840-driver:

   --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 scan.

CONFIGURATION

   This backend does not support a configuration file right now.

FILES

   /usr/lib/arch_triplet/sane/libsane-sm3840.a
          The static library implementing this backend.

   /usr/lib/arch_triplet/sane/libsane-sm3840.so
          The shared library implementing this backend (present on systems
          that support dynamic loading).

ENVIRONMENT

   SANE_DEBUG_SM3840
          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.
