sane-epsonds - SANE backend for EPSON ESC/I-2 scanners
The sane-epsonds library implements a SANE (Scanner Access Now Easy)
backend that provides access to Epson ESC/I-2 scanners.
Valid command line options and their syntax can be listed by using
scanimage --help -d epsonds
Not all devices support all options.
The --mode switch selects the basic mode of operation of the
scanner. Valid choices are Lineart, Gray and Color. The Lineart
mode is black and white only, Gray will produce 256 levels of
gray or more depending on the scanner and Color means 24 bit
color mode or more depending on the scanner. Some scanners will
internally use 36 bit color, their external interface however
may only support 24 bits.
The --depth option selects the bit depth the scanner is using.
This option is only available for scanners that support more
than one bit depth. Older scanners will always transfer the
image in 8bit mode. Newer scanners allow one to select either 8
bits, 12 or 14 bits per color channel. For a color scan this
means an effective color depth of 36 or 42 bits over all three
channels. The valid choices depend on the scanner model.
The --resolution switch selects the resolution for a scan. Some
EPSON scanners will scan in any resolution between the lowest
and highest possible value. The list reported by the scanner can
be displayed using the "--help -d epson" parameters to scanim-
The geometry options -l -t -x -y control the scan area: -l sets
the top left x coordinate, -t the top left y coordinate, -x
selects the width and -y the height of the scan area. All param-
eters are specified in millimeters.
The --source option selects the scan source. Valid options
depend on the installed options. The default is "Flatbed".
The --eject option ejects the sheet in the ADF.
The --adf-mode option select the ADF mode (simplex/duplex).
The configuration file /usr/local/etc/sane.d/epsonds.conf specifies the
device(s) that the backend will use. Possible connection types are:
USB For not automatically detected USB scanners, their VENDOR and
PRODUCT ID can be specified manually in the config file. More
information about valid syntax for USB devices can be found in
Network (not yet supported)
Network scanners can be auto-discovered if autodiscovery is
specified after net keyword. An IP address to connect to can
also be used.
The static library implementing this backend.
The shared library implementing this backend (present on systems
that support dynamic loading).
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. Values around 11-16 will usu-
ally be enough for a bug report.
