NAME

6       sane-artec_eplus48u - SANE backend for the scanner Artec E+ 48U and re-
7       badged models
8

DESCRIPTION

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
15       A    complete   list   of   supported   devices   can   be   found   on
16       http://www.sane-project.org/sane-supported-devices.html.
17
18       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
22       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.

KERNEL ISSUES

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
32       actions.  For  setting  permissions and general USB information look at
33       sane-usb(5).
34
35       When you are using the scanner module, a Linux kernel 2.4.12  or  newer
36       is required.

FIRMWARE FILE

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.

CONFIGURATION

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
58       Every usb section can have additional options
59
60       artecFirmwareFile /usr/share/sane/artec_eplus48u/Artec48.usb
61              The path to the firmware file. This option is required.
62
63       redGamma 1.0
64
65       greenGamma 1.0
66
67       blueGamma 1.0
68
69       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
74       redOffset 0x28
75
76       greenOffset 0x2f
77
78       blueOffset 0x2f
79
80       redExposure 0xa7
81
82       greenExposure 0x116
83
84       blueExposure 0xdc
85              These  are  the default values for offset and exposure time. You
86              can e.g. change them to speed up calibration, if you don't  want
87              to save the calibration data to disk.
88
89       vendorString Artec
90
91       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.

FILES

97       /usr/local/etc/sane.d/artec_eplus48u.conf
98              The   backend   configuration  file  (see  also  description  of
99              SANE_CONFIG_DIR below).
100
101       /usr/local/lib/sane/libsane-artec_eplus48u.a
102              The static library implementing this backend.
103
104       /usr/local/lib/sane/libsane-artec_eplus48u.so
105              The shared library implementing this backend (present on systems
106              that support dynamic loading).
107

ENVIRONMENT

109       SANE_CONFIG_DIR
110              This environment variable specifies the list of directories that
111              may contain the configuration file.  Under UNIX, the directories
112              are  separated  by a colon (`:'), under OS/2, they are separated
113              by a semi-colon (`;').  If this variable is not set, the config‐
114              uration  file is searched in two default directories: first, the
115              current working directory (".") and then in /etc/sane.d.  If the
116              value  of the environment variable ends with the directory sepa‐
117              rator character, then the default directories are searched after
118              the  explicitly  specified  directories.  For  example,  setting
119              SANE_CONFIG_DIR to "/tmp/config:" would  result  in  directories
120              tmp/config, ., and /etc/sane.d being searched (in this order).
121
122       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
127              Example: export SANE_DEBUG_ARTEC_EPLUS48U=3

BUGS

144       This backend has been tested on Linux only. If you are using  it  on  a
145       different platform, please contact us.
146
147       Interpolation with 1200 dpi is weak.
148
149       Support for buttons is missing due to missing support in SANE.
