6 sane-teco3 - SANE backend for TECO / RELISYS scanners
7
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 The scanners that should work with this backend are:
16 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 The TECO VM number can usually be found at the back of the scanner. It
27 is also part of the FCC ID.
28 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 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 Valid command line options and their syntax can be listed by using
38 scanimage --help -d teco3
39 Scan Mode
42 --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 --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 Geometry options
57 -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 Enhancement options
68 --custom-gamma
71 (color mode only) allows the user to specify a gamma table (see
72 the next 3 parameters).
73 --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 --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 --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 --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".
95
99 The configuration file /etc/sane.d/teco3.conf supports only one infor‐
100 mation: the device name to use (eg /dev/scanner).
101
105 /usr/lib64/sane/libsane-teco3.a
106 The static library implementing this backend.
107 /usr/lib64/sane/libsane-teco3.so
109 The shared library implementing this backend (present on systems
110 that support dynamic loading).
111
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.
120
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.

131 Not much.
