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 us‐
12 ing the GT6816 chipset like the Artec E+ 48U. These scanners have a
13 contact image sensor (CIS).
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(1) or syslog) to me. Even if
26 the 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(1) without further ac‐
32 tions. 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:264vers.
47
50 The contents of the artec_eplus48u.conf file is a list of usb lines
51 containing vendor and product ids that correspond to USB scanners. The
52 file can also contain option lines. Empty lines and lines starting
53 with a hash mark (#) are ignored. The scanners are autodetected by usb
54 vendor_id product_id statements which are already included into
55 artec_eplus48u.conf . "vendor_id" and "product_id" are hexadecimal
56 numbers that identify the scanner.
57 Every usb section can have additional options.
59 artecFirmwareFile /usr/share/sane/artec_eplus48u/Artec48.usb
61 The path to the firmware file. This option is required.
62 redGamma 1.0
64 greenGamma 1.0
66 blueGamma 1.0
68 masterGamma 1.9
70 These are the default gamma values. If you set the "Defaults"
71 option with a frontend, then the gamma options are reset to the
72 values specified here.
73 redOffset 0x28
75 greenOffset 0x2f
77 blueOffset 0x2f
79 redExposure 0xa7
81 greenExposure 0x116
83 blueExposure 0xdc
85 These are the default values for offset and exposure time. You
86 can change them (e.g. to speed up calibration) if you don't want
87 to save the calibration data permanently.
88 vendorString Artec
90 modelString E+ 48U
92 By default, the scanner is reported as "Artec E+ 48U". If you
93 don't like this, e.g. because you have an Tevion MD 9693, then
94 change the options accordingly.
95
97 /usr/local/etc/sane.d/artec_eplus48u.conf
98 The backend configuration file (see also description of
99 SANE_CONFIG_DIR below).
100 /usr/local/lib/sane/libsane-artec_eplus48u.a
102 The static library implementing this backend.
103 /usr/local/lib/sane/libsane-artec_eplus48u.so
105 The shared library implementing this backend (present on systems
106 that support dynamic loading).
107
109 SANE_CONFIG_DIR
110 This environment variable specifies the list of directories that
111 may contain the configuration file. On *NIX systems, the direc‐
112 tories are separated by a colon (`:'), under OS/2, they are sep‐
113 arated by a semi-colon (`;'). If this variable is not set, the
114 configuration file is searched in two default directories:
115 first, the current working directory (".") and then in
116 /etc/sane.d. If the value of the environment variable ends with
117 the directory separator character, then the default directories
118 are searched after the explicitly specified directories. For ex‐
119 ample, setting SANE_CONFIG_DIR to "/tmp/config:" would result in
120 directories tmp/config, ., and /etc/sane.d being searched (in
121 this order).
122 SANE_DEBUG_ARTEC_EPLUS48U
124 If the library was compiled with debug support enabled, this en‐
125 vironment variable controls the debug level for this backend.
126 Higher debug levels increase the verbosity of the output.
127 Example: export SANE_DEBUG_ARTEC_EPLUS48U=3

137 This backend is based on the gt68xx test-program written by Sergey
138 Vlasov, Andreas Nowack, and David Stevenson. Thanks to everyone who
139 tested the backend or reported bugs.
140 This man page is based on man sane-gt68xx(5), written by Henning Meier-
141 Geinitz.
142
145 This backend has been tested on Linux only. If you are using it on a
146 different platform, please contact us.
147 Interpolation with 1200 dpi is weak.
149 Support for buttons is missing due to missing support in SANE.
151 Please contact us if you find a bug:
