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 /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/arch_triplet/sane/libsane-umax1220u.a

   The shared library implementing this backend:
          /usr/lib/arch_triplet/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 reporting
   bugs,  please  run  the backend with SANE_DEBUG_UMAX1220U set to 10 and
