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  con-
       tact 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/lib64/sane/libsane-sm3840.a
	      The static library implementing this backend.

       /usr/lib64/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.
