6 sane-artec_eplus48u - SANE backend for the scanner Artec E+ 48U and re-
7 badged models
8
10 The sane-artec_eplus48u library implements a SANE (Scanner Access Now
11 Easy) backend that provides access to several USB flatbed scanners
12 using the GT6816 chipset like the Artec E+ 48U. These scanners have a
13 contact image sensor (CIS) and an USB interface.
14 A complete list of supported devices can be found on
16 http://www.sane-project.org/sane-supported-devices.html.
17 This is ALPHA software. Especially if you test new or untested scan‐
19 ners, keep your hand at the scanner's plug and unplug it, if the head
20 bumps at the end of the scan area.
21 If you own a scanner other than the ones mentioned on the list that
23 works with this backend, please let us know this by sending the scan‐
24 ner's exact model name and the USB vendor and product ids (e.g. from
25 /proc/bus/usb/devices, sane-find-scanner or syslog) to me. Even if the
26 scanner's name is only slightly different from the models mentioned
27 above, please let me know.
28
30 If libusb-0.1.6 or later is installed, this section can be skipped. The
31 scanner should be found by sane-find-scanner without further actions.
32 For setting permissions and general USB information look at
33 sane-usb(5).
34 When you are using the scanner module, a Linux kernel 2.4.12 or newer
36 is required.
37
40 You need a firmware file for your scanner. That's a small file contain‐
41 ing software that will be uploaded to the scanner's memory. For the
42 scanners mentioned above, it's usually named Artec48.usb or 1200.usb.
43 You can find it on the installation CD that was provided by the manu‐
44 facturer, normally in the directory Win98, WinMe or similar. If the
45 Windows-driver is installed on your computer, then you can also find
46 the firmware file under c:\windows\system32\drivers.
47
49 The contents of the artec_eplus48u.conf file is a list of usb lines
50 containing vendor and product ids that correspond to USB scanners. The
51 file can also contain option lines. Empty lines and lines starting
52 with a hash mark (#) are ignored. The scanners are autodetected by usb
53 vendor_id product_id statements which are already included into
54 artec_eplus48u.conf . "vendor_id" and "product_id" are hexadecimal
55 numbers that identify the scanner.
56 Every usb section can have additional options
58 artecFirmwareFile /usr/share/sane/artec_eplus48u/Artec48.usb
60 The path to the firmware file. This option is required.
61 redGamma 1.0
63 greenGamma 1.0
65 blueGamma 1.0
67 masterGamma 1.9
69 These are the default gamma values. If you set the "Defaults"
70 option with a frontend, then the gamma options are reset to the
71 values specified here.
72 redOffset 0x28
74 greenOffset 0x2f
76 blueOffset 0x2f
78 redExposure 0xa7
80 greenExposure 0x116
82 blueExposure 0xdc
84 These are the default values for offset and exposure time. You
85 can e.g. change them to speed up calibration, if you don't want
86 to save the calibration data to disk.
87 vendorString Artec
89 modelString E+ 48U
91 By default, the scanner is reported as "Artec E+ 48U". If you
92 don't like this, e.g. because you have an Tevion MD 9693, then
93 change the options accordingly.
94
96 /usr/local/etc/sane.d/artec_eplus48u.conf
97 The backend configuration file (see also description of
98 SANE_CONFIG_DIR below).
99 /usr/local/lib/sane/libsane-artec_eplus48u.a
101 The static library implementing this backend.
102 /usr/local/lib/sane/libsane-artec_eplus48u.so
104 The shared library implementing this backend (present on systems
105 that support dynamic loading).
106
108 SANE_CONFIG_DIR
109 This environment variable specifies the list of directories that
110 may contain the configuration file. Under UNIX, the directories
111 are separated by a colon (`:'), under OS/2, they are separated
112 by a semi-colon (`;'). If this variable is not set, the config‐
113 uration file is searched in two default directories: first, the
114 current working directory (".") and then in
115 /usr/local/etc/sane.d. If the value of the environment variable
116 ends with the directory separator character, then the default
117 directories are searched after the explicitly specified directo‐
118 ries. For example, setting SANE_CONFIG_DIR to "/tmp/config:"
119 would result in directories "tmp/config", ".", and
120 "/usr/local/etc/sane.d" being searched (in this order).
121 SANE_DEBUG_ARTEC_EPLUS48U
123 If the library was compiled with debug support enabled, this
124 environment variable controls the debug level for this backend.
125 Higher debug levels increase the verbosity of the output.
126 Example: export SANE_DEBUG_ARTEC_EPLUS48U=3

136 This backend is based on the gt68xx test-program written by Sergey
137 Vlasov, Andreas Nowack, and David Stevenson. Thanks to everyone who
138 tested the backend or reported bugs.
139 This man page is based on man sane-gt68xx, written by Henning Meier-
140 Geinitz.
141
143 This backend has been tested on Linux only. If you are using it on a
144 different platform, please contact us.
145 Interpolation with 1200 dpi is weak.
147 Support for buttons is missing due to missing support in SANE.
149 Please contact us if you find a bug:
