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@alioth-lists.debian.net).

CONFIGURATION

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

       Its  content  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/x86_64-linux-gnu/sane/libsane-umax1220u.a

       The shared library implementing this backend:
              /usr/lib/x86_64-linux-gnu/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.
