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.
