NAME
sane-epsonds - SANE backend for EPSON ESC/I-2 scanners
DESCRIPTION
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.
Scan Mode
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 scanimage(1).
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
parameters 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).
CONFIGURATION FILE
The configuration file /opt/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
sane-usb(5).
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.
FILES
/opt/local/lib/sane/libsane-epsonds.a
The static library implementing this backend.
/opt/local/lib/sane/libsane-epsonds.so
The shared library implementing this backend (present on systems
that support dynamic loading).
ENVIRONMENT
SANE_DEBUG_EPSONDS
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 usually
be enough for a bug report.
