NAME

6       sane-teco3 - SANE backend for TECO / RELISYS scanners
7

DESCRIPTION

9       The  sane-teco3  library  implements  a  SANE (Scanner Access Now Easy)
10       backend that provides access to some TECO SCSI flatbed  scanners.  This
11       backend  should be considered alpha-quality software! TECO scanners are
12       sold under various brands like RELYSIS, PIOTECH,  TRUST.  This  backend
13       may or may not support yours.
14
15       The scanners that should work with this backend are:
16
17                Vendor Model                 TECO model   status
18                ---------------------------  ----------  ----------
19                Relisys Scorpio                VM3552     tested
20                Plustek OpticPro 2400SP        VM3552     untested
21                PIOTECH Splendeur 3024         VM3552     tested
22                Trust Imagery 2400 SP          VM3552     tested
23                Trust Imagery 4800 SP+         VM3552     tested
24                Trust Imagery 9600 SP          VM3552     untested
25
26       The  TECO VM number can usually be found at the back of the scanner. It
27       is also part of the FCC ID.
28
29       The options the backend supports can either be selected through command
30       line  options  to  programs  like  scanimage or through GUI elements in
31       xscanimage or xsane.
32
33       If you have any success with a scanner not listed here, or if you  have
34       any strange behavior, please report to the backend maintainer or to the
35       SANE mailing list.
36
37       Valid command line options and their syntax can be listed by using
38              scanimage --help -d teco3
39
40
41       Scan Mode
42
43
44       --mode selects the basic mode of operation of the scanner valid choices
45              are  Black  & White , Grayscale and Color The Black & White mode
46              is black and white only (1 bit). Grayscale will produce 256 lev‐
47              els of gray (8 bits). Color will produce a 24 bits color image.
48
49
50       --resolution
51              selects  the resolution for a scan. The scanner can do all reso‐
52              lutions between 1 and 1200, in increments of 1.
53
54
55
56       Geometry options
57
58
59       -l -t -x -y
60              control the scan area: -l sets the top left x coordinate, -t the
61              top left y coordinate, -x selects the width and -y the height of
62              the scan area. All parameters are specified  in  millimeters  by
63              default.
64
65
66
67       Enhancement options
68
69
70       --custom-gamma
71              (color  mode only) allows the user to specify a gamma table (see
72              the next 3 parameters).
73
74
75       --red-gamma-table
76              (color mode only) can be used to download a user  defined  gamma
77              table for the red channel. The table must be 1024 bytes long.
78
79
80       --green-gamma-table
81              (color  mode  only) can be used to download a user defined gamma
82              table for the green channel. The table must be 1024 bytes long.
83
84
85       --blue-gamma-table
86              (color mode only) can be used to download a user  defined  gamma
87              table for the blue channel. The table must be 1024 bytes long.
88
89
90
91       --preview
92              requests a preview scan. The resolution used for that scan is 22
93              dpi and the scan area is the maximum allowed. The scan  mode  is
94              user selected. The default is "no".

CONFIGURATION FILE

99       The  configuration file /etc/sane.d/teco3.conf supports only one infor‐
100       mation: the device name to use (eg /dev/scanner).

103

FILES

105       /usr/lib64/sane/libsane-teco3.a
106              The static library implementing this backend.
107
108       /usr/lib64/sane/libsane-teco3.so
109              The shared library implementing this backend (present on systems
110              that support dynamic loading).
111
112
113

ENVIRONMENT

115       SANE_DEBUG_TECO3
116              If  the  library  was  compiled with debug support enabled, this
117              environment variable controls the debug level for this  backend.
118              E.g.,  a  value  of 128 requests all debug output to be printed.
119              Smaller levels reduce verbosity.

122

LIMITATIONS

124       The windows TWAIN driver has many more options than this SANE  backend.
125       However  they  are  only software adjustments. This backend only imple‐
126       ments what the scanner can support.
