sane-sm3840(5)		 SANE Scanner Access Now Easy		sane-sm3840(5)

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.
