NAME

6       sane-epsonds - SANE backend for EPSON ESC/I-2 scanners
7

DESCRIPTION

9       The  sane-epsonds  library  implements a SANE (Scanner Access Now Easy)
10       backend that provides access to Epson ESC/I-2 scanners.
11
12       Valid command line options and their syntax can be listed by using
13
14              scanimage --help -d epsonds
15
16       Not all devices support all options.
17
18       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
27              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
35              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
41              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
46              The  --source  option selects the scan source. Valid options de‐
47              pend on the installed options. The default is "Flatbed".
48
49              The --eject option ejects the sheet in the ADF.
50
51              The --adf-mode option select the ADF mode (simplex/duplex).

CONFIGURATION FILE

55       The configuration file /etc/sane.d/epsonds.conf specifies the device(s)
56       that the backend will use. Possible connection types are:
57
58       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
63       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

FILES

69       /usr/lib64/sane/libsane-epsonds.a
70              The static library implementing this backend.
71
72       /usr/lib64/sane/libsane-epsonds.so
73              The shared library implementing this backend (present on systems
74              that support dynamic loading).
75

ENVIRONMENT

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.
