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 @CONFIGDIR@/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:
              @CONFIGDIR@/umax1220u.conf

       The static library implementing this backend:
              @LIBDIR@/libsane-umax1220u.a

       The shared library implementing this backend:
              @LIBDIR@/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.
