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/lib64/sane/libsane-umax1220u.a

       The shared library implementing this backend:
	      /usr/lib64/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 report-
       ing bugs, please run the backend with SANE_DEBUG_UMAX1220U set to 10 and attach a copy of the log messages.
