sane-umax1220u(5)        SANE Scanner Access Now Easy        sane-umax1220u(5)


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 /usr/local/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:
              /usr/local/etc/sane.d/umax1220u.conf

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

       The shared library implementing this backend:
              /usr/local/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.

REPORTING BUGS

       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.
