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.  Re-
       fer 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/local/lib/sane/libsane-sm3840.a
              The static library implementing this backend.

       /usr/local/lib/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 en-
              vironment  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.
