SANE Scanner Access Now Easy                     sane-cardscan(5)



NAME
     sane-cardscan - SANE backend for  Corex  CardScan  800c  usb
     scanner


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

     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 con-
     trolling 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 confi-
     guration 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.


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  possi-
          ble,  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.
