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 ig-
       nored. 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 en-
	      vironment	 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_can-
       cel().

       If  you	try scanning an	image which is too small, you will get I/O er-
       rors. Be	sure to	adjust the scan	area before doing a scan, since	by de-
       fault, 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.
