6 sane-epsonds - SANE backend for EPSON ESC/I-2 scanners
7
9 The sane-epsonds library implements a SANE (Scanner Access Now Easy)
10 backend that provides access to Epson ESC/I-2 scanners.
11 Valid command line options and their syntax can be listed by using
13 scanimage --help -d epsonds
14 Not all devices support all options.
15 Scan Mode
17 The --mode switch selects the basic mode of operation of the
18 scanner. Valid choices are Lineart, Gray and Color. The Lineart
19 mode is black and white only, Gray will produce 256 levels of
20 gray or more depending on the scanner and Color means 24 bit
21 color mode or more depending on the scanner. Some scanners will
22 internally use 36 bit color, their external interface however
23 may only support 24 bits.
24 The --depth option selects the bit depth the scanner is using.
26 This option is only available for scanners that support more
27 than one bit depth. Older scanners will always transfer the
28 image in 8bit mode. Newer scanners allow one to select either 8
29 bits, 12 or 14 bits per color channel. For a color scan this
30 means an effective color depth of 36 or 42 bits over all three
31 channels. The valid choices depend on the scanner model.
32 The --resolution switch selects the resolution for a scan. Some
34 EPSON scanners will scan in any resolution between the lowest
35 and highest possible value. The list reported by the scanner can
36 be displayed using the "--help -d epson" parameters to scanim‐
37 age.
38 The geometry options -l -t -x -y control the scan area: -l sets
40 the top left x coordinate, -t the top left y coordinate, -x
41 selects the width and -y the height of the scan area. All param‐
42 eters are specified in millimeters.
43 The --source option selects the scan source. Valid options
45 depend on the installed options. The default is "Flatbed".
46 The --eject option ejects the sheet in the ADF.
48 The --adf-mode option select the ADF mode (simplex/duplex).

53 The configuration file /etc/sane.d/epsonds.conf specifies the device(s)
54 that the backend will use. Possible connection types are:
55 USB For not automatically detected USB scanners, their VENDOR and
57 PRODUCT ID can be specified manually in the config file. More
58 information about valid syntax for USB devices can be found in
59 sane-usb(5).
60 Network (not yet supported)
62 Network scanners can be auto-discovered if autodiscovery is
63 specified after net keyword. An IP address to connect to can
64 also be used.
65
67 /usr/lib64/sane/libsane-epsonds.a
68 The static library implementing this backend.
69 /usr/lib64/sane/libsane-epsonds.so
71 The shared library implementing this backend (present on systems
72 that support dynamic loading).
73
75 SANE_DEBUG_EPSONDS
76 If the library was compiled with debug support enabled, this
77 environment variable controls the debug level for this backend.
78 E.g., a value of 128 requests all debug output to be printed.
79 Smaller levels reduce verbosity. Values around 11-16 will usu‐
80 allybe enough for a bug report.
