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
15 Not all devices support all options.
17 Scan Mode
19 The --mode switch selects the basic mode of operation of the
20 scanner. Valid choices are Lineart, Gray and Color. The Lineart
21 mode is black and white only, Gray will produce 256 levels of
22 gray or more depending on the scanner and Color means 24 bit
23 color mode or more depending on the scanner. Some scanners will
24 internally use 36 bit color, their external interface however
25 may only support 24 bits.
26 The --depth option selects the bit depth the scanner is using.
28 This option is only available for scanners that support more
29 than one bit depth. Older scanners will always transfer the im‐
30 age in 8bit mode. Newer scanners allow one to select either 8
31 bits, 12 or 14 bits per color channel. For a color scan this
32 means an effective color depth of 36 or 42 bits over all three
33 channels. The valid choices depend on the scanner model.
34 The --resolution switch selects the resolution for a scan. Some
36 EPSON scanners will scan in any resolution between the lowest
37 and highest possible value. The list reported by the scanner can
38 be displayed using the "--help -d epson" parameters to scanim‐
39 age(1).
40 The geometry options -l -t -x -y control the scan area: -l sets
42 the top left x coordinate, -t the top left y coordinate, -x se‐
43 lects the width and -y the height of the scan area. All parame‐
44 ters are specified in millimeters.
45 The --source option selects the scan source. Valid options de‐
47 pend on the installed options. The default is "Flatbed".
48 The --eject option ejects the sheet in the ADF.
50 The --adf-mode option select the ADF mode (simplex/duplex).
52
55 The configuration file /etc/sane.d/epsonds.conf specifies the device(s)
56 that the backend will use. Possible connection types are:
57 USB For not automatically detected USB scanners, their VENDOR and
59 PRODUCT ID can be specified manually in the config file. More
60 information about valid syntax for USB devices can be found in
61 sane-usb(5).
62 Network (not yet supported)
64 Network scanners can be auto-discovered if autodiscovery is
65 specified after net keyword. An IP address to connect to can
66 also be used.
67
69 /usr/lib64/sane/libsane-epsonds.a
70 The static library implementing this backend.
71 /usr/lib64/sane/libsane-epsonds.so
73 The shared library implementing this backend (present on systems
74 that support dynamic loading).
75
77 SANE_DEBUG_EPSONDS
78 If the library was compiled with debug support enabled, this en‐
79 vironment variable controls the debug level for this backend.
80 E.g., a value of 128 requests all debug output to be printed.
81 Smaller levels reduce verbosity. Values around 11-16 will usu‐
82 ally be enough for a bug report.
