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 SUPORT
     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  confi-
     guration     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/lib/sane/libsane-umax1220u.a

     The shared library implementing this backend:
          /usr/lib/sane/libsane-umax1220u.so (present on  systems
          that support dynamic loading)

ENVIRONMENT
     SANEDEBUGUMAX1220U
          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:

          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 SANEDEBUGUMAX1220U=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
     sanecancel().

     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.
