    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@alioth-lists.debian.net).

## 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
           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:
                  /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
                  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_can‐
           cel().

           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.
