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

NAME

       sane-cardscan - SANE backend for Corex CardScan usb scanners

DESCRIPTION

       The  sane-cardscan  library  implements	a  SANE  (Scanner Access Now Easy) backend which provides access to the Corex CardScan 800c & 600c
       small-format scanners.

       The backend supports only grayscale and color modes and media of (theoretically) infinite length.

       This backend may support other scanners. The best way to determine level of support is to get a trace of the windows driver in action,  and
       send it to the author.

OPTIONS

       The cardscan backend supports the following options:

       mode m
	      Selects the mode for the scan. Options are "Gray" and "Color".

CONFIGURATION FILE

       The  configuration file "cardscan.conf" is used to tell the backend how to look for scanners, and provide options controlling the operation
       of the backend.	This file is read each time the frontend asks the backend for a list of scanners, generally only when the frontend starts.
       If  the	configuration  file  is missing, the backend will use a set of compiled defaults, which are identical to the default configuration
       file shipped with SANE.

       Scanners can be specified in the configuration file in 2 ways:

       "usb 0x04c5 0x1042" (or other vendor/product ids)
	      Requests backend to search all usb busses in the system for a device which uses that vendor and product id. The device will then	be
	      queried to determine if it is a cardscan scanner.

       "usb /dev/usb/scanner0" (or other device file)
	      Some systems use a kernel driver to access usb scanners. This method is untested.

       Additionally, there are two configuration options that control the protocol used by the backend:

       "lines_per_block 16" (or other number from 1 to 32)
	      Controls	the  number of lines of image data which will be aquired in each pass.	Older scanners will require this number set lower,
	      often 1.

       "has_cal_buffer 1" (1 or 0)
	      Causes the backend to get calibration data from scanner during initialization.  Older scanners do not support this request, and must
	      be set to 0.

ENVIRONMENT

       The backend uses a single environment variable, SANE_DEBUG_CARDSCAN, which enables debugging output to stderr. Valid values are:

	      5  Errors
	      10 Function trace
	      15 Function detail
	      20 Option commands
	      25 SCSI/USB trace
	      30 SCSI/USB detail
	      35 Useless noise

KNOWN ISSUES

	      The  scanner  does  not seem to have much control possible, so the backend cannot set x/y coordinate values, resolutions, etc. These
	      things could be simulated in the backend, but there are plenty of command line tools.
	      The backend also does not send all the commands that the windows driver does, so it may not function the same.
	      The backend does not have the calibration or ejection options of the windows driver.

NAME

       sane-sm3600 - SANE backend for Microtek scanners with M011 USB chip

DESCRIPTION

       The sane-sm3600 library implements a SANE (Scanner Access Now Easy) backend that provides access to some Microtek scanners with the Toshiba
       M011 custom USB chip.  This backend should be considered alpha.

       There are also backends for Microtek scanners with SCSI command set.  Refer to sane-microtek(5) and sane-microtek2(5) for details.

       At present, the following scanners are known positively to work with this backend:

	      Vendor	 Product id:	 Remark:
	      --------	 --------------  -----------
	      Microtek	 ScanMaker 3600  all modes ok
	      Microtek	 ScanMaker 3700  reported to work
	      Microtek	 ScanMaker 3750  reported to work

       If you own a Microtek scanner with the M011 chip other than the ones listed above, it may or may not work with SANE!

FRONTEND OPTIONS

       This backend dynamically enables the options for the frontend, that are supported by the scanner in dependence  of  the	scanning-mode  and
       other options. Not supported options are disabled.

       The following options are supported by the Microtek2-driver:

       Color, grayscale, halftone and lineart scans.

       contrast, brightness, control, gamma correction.

DEVICE NAMES

       This backend does not support device names in a standardized form.

CONFIGURATION

       This backend does not support a configuration file right now.

FILES

       /usr/lib64/sane/libsane-sm3600.a
	      The static library implementing this backend.

       /usr/lib64/sane/libsane-sm3600.so
	      The shared library implementing this backend (present on systems that support dynamic loading).

ENVIRONMENT

       SANE_DEBUG_SM3600
	      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_SM3600 to 1.

	      E.g. just say:
	      export SANE_DEBUG_SM3600=5
