sane-umax1220u  -  SANE  backend  for  the UMAX Astra 1220U and similar


   The sane-umax1220 library implements a SANE (Scanner Access  Now  Easy)
   backend for the the UMAX Astra 1220U and similar scanners.

   For    more    information    on    this    backend,    please    visit


   This backend is also able to drive the  UMAX  Astra  1600U/2000U/2100U.
   The  2100U is confirmed to work. For the other scanners no reports have
   been received yet. Please contact us and tell us if your scanner  works


   Usually,  no  manual configuration is necessary. The configuration file
   for this backend resides in /etc/sane.d/umax1220u.conf.

   Its contents is a list of device names that correspond  to  UMAX  Astra
   scanners.   Empty  lines  and  lines  starting with a hash mark (#) are
   ignored. A sample configuration file is shown below:

    #usb vendor product
    usb 0x1606 0x0010
    # Device list for non-linux systems

   See sane-usb(5) for information on how to set the access permissions on
   the usb device files.


   The backend configuration file:

   The static library implementing this backend:

   The shared library implementing this backend:
          /usr/lib/arch_triplet/sane/    (present   on
          systems that support dynamic loading)


          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:

          SANE_DEBUG_UMAX1220U values

          Number  Remark

           1       print failures
           2       print information
           3       print high-level function calls
           4       print high-level function checkpoints
           9       print mid-level function calls
           10      print mid-level function checkpoints
           80      print protocol-level function entry
           90      print protocol-level function exit

          export SANE_DEBUG_UMAX1220U=10


   600 dpi scanning may fail for large image sizes.

   If  you  keep getting I/O errors, try cycling the power on your scanner
   to reset it.

   There  is  no  way  to  cancel  a  scan,  since  the   driver   ignores

   If  you  try  scanning  an  image  which is too small, you will get I/O
   errors. Be sure to adjust the scan area before doing a scan,  since  by
   default, the scan area is zero.

   This  backend  isn't actively maintained. Nevertheless, bug reports and
   comments should be sent to the sane-devel mailing list.  When reporting
   bugs,  please  run  the backend with SANE_DEBUG_UMAX1220U set to 10 and
   attach a copy of the log messages.
