NAME

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

DESCRIPTION

       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 http://umax1220u-
       sane.sourceforge.net/.

UMAX ASTRA 1600U/2000U/2100U SUPPORT

       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
       (sane-devel@lists.alioth.debian.org).

CONFIGURATION

       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
        /dev/scanner
        /dev/usb/scanner0

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

FILES

       The backend configuration file:
              /etc/sane.d/umax1220u.conf

       The static library implementing this backend:
              /usr/lib/sane/libsane-umax1220u.a

       The shared library implementing this backend:
              /usr/lib/sane/libsane-umax1220u.so   (present  on  systems  that
              support dynamic loading)

ENVIRONMENT

       SANE_DEBUG_UMAX1220U
              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

       Example:
              export SANE_DEBUG_UMAX1220U=10

KNOWN BUGS

       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
       sane_cancel().

       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.
