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 sane-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/x86_64-linux-gnu/sane/libsane-sm3840.a
              The static library implementing this backend.

       /usr/lib/x86_64-linux-gnu/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.
