.SH NAME
|
|
sane\-epsonds \- SANE backend for EPSON ESC/I-2 scanners
|
|
.SH DESCRIPTION
|
|
The
|
|
.B sane\-epsonds
|
|
library implements a SANE (Scanner Access Now Easy) backend that provides access
|
|
to Epson ESC/I-2 scanners.
|
|
.PP
|
|
Valid command line options and their syntax can be listed by using
|
|
.PP
|
|
.RS
|
|
scanimage \-\-help \-d epsonds
|
|
.RE
|
|
.PP
|
|
Not all devices support all options.
|
|
.TP
|
|
.I Scan Mode
|
|
The
|
|
.B \-\-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
|
|
.B \-\-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
|
|
.B \-\-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
|
|
.BR scanimage (1).
|
|
|
|
The geometry options
|
|
.B \-l \-t \-x \-y
|
|
control the scan area:
|
|
.B \-l
|
|
sets the top left x coordinate,
|
|
.B \-t
|
|
the top left y coordinate,
|
|
.B \-x
|
|
selects the width and
|
|
.B \-y
|
|
the height of the scan area. All parameters are specified in millimeters.
|
|
|
|
The
|
|
.B \-\-source
|
|
option selects the scan source. Valid options depend on the installed
|
|
options. The default is "Flatbed".
|
|
|
|
The
|
|
.B \-\-eject
|
|
option ejects the sheet in the ADF.
|
|
|
|
The
|
|
.B \-\-adf-mode
|
|
option select the ADF mode (simplex/duplex).
|
|
|
|
.SH CONFIGURATION FILE
|
|
The configuration file
|
|
.I @CONFIGDIR@/epsonds.conf
|
|
specifies the device(s) that the backend will use. Possible connection types are:
|
|
.TP
|
|
.B 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
|
|
.BR sane\-usb (5).
|
|
.TP
|
|
.B Network (not yet supported)
|
|
Network scanners can be auto-discovered if
|
|
.B autodiscovery
|
|
is specified after
|
|
.B net
|
|
keyword. An IP address to connect to can also be used.
|
|
.SH FILES
|
|
.TP
|
|
.I @LIBDIR@/libsane\-epsonds.a
|
|
The static library implementing this backend.
|
|
.TP
|
|
.I @LIBDIR@/libsane\-epsonds.so
|
|
The shared library implementing this backend (present on systems that
|
|
support dynamic loading).
|
|
.SH ENVIRONMENT
|
|
.TP
|
|
.B 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.
