NAME

6       sane-teco1 - SANE backend for TECO / RELISYS scanners
7

DESCRIPTION

9       The  sane-teco1  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 beta-quality software! TECO scanners are
12       sold under various brands like RELISYS, PIOTECH,  TRUST.  This  backend
13       may or may not support yours.
14
15       The scanners that should work with this backend are:

38
39       Note  that  the  untested  scanner  will not be directly supported. You
40       should contact the author for that.
41
42       The TECO VM number can usually be found at the back of the scanner.  It
43       is  also  part of the FCC ID. "sane-find-scanner -v" will also show the
44       scsi inquiry, and if it is a TECO scanner, the name will be there too.
45
46       The options the backend supports can either be selected through command
47       line  options  to  programs  like  scanimage or through GUI elements in
48       xscanimage or xsane.
49
50       If you have any success with a scanner not listed here, or if you  have
51       any strange behavior, please report to the backend maintainer or to the
52       SANE mailing list.
53
54       Valid command line options and their syntax can be listed by using
55              scanimage --help -d teco1
56
57
58       Scan Mode
59
60
61       --mode selects the basic mode of operation of the scanner valid choices
62              are  Black  & White , Grayscale and Color The Black & White mode
63              is black and white only (1 bit). Grayscale will produce 256 lev‐
64              els of gray (8 bits). Color will produce a 24 bits color image.
65
66
67       --resolution
68              selects  the resolution for a scan. The scanner can do all reso‐
69              lutions between 1 and 600, in increments of 1.
70
71
72
73       Geometry options
74
75
76       -l -t -x -y
77              control the scan area: -l sets the top left x coordinate, -t the
78              top left y coordinate, -x selects the width and -y the height of
79              the scan area. All parameters are specified  in  millimeters  by
80              default.
81
82
83
84       Enhancement options
85
86
87       --custom-gamma
88              (color  mode only) allows the user to specify a gamma table (see
89              the next 3 parameters).
90
91
92       --red-gamma-table
93              (color mode only) can be used to download a user  defined  gamma
94              table for the red channel. The table must be 256 bytes long.
95
96
97       --green-gamma-table
98              (color  mode  only) can be used to download a user defined gamma
99              table for the green channel. The table must be 256 bytes long.
100
101
102       --blue-gamma-table
103              (color mode only) can be used to download a user  defined  gamma
104              table for the blue channel. The table must be 256 bytes long.
105
106
107       --dither
108              (Black  &  White  only)  select the dither mask to use. Possible
109              values are Line art , 2x2 , 3x3 , 4x4 bayer , 4x4 smooth  ,  8x8
110              bayer , 8x8 smooth , 8x8 horizontal and 8x8 vertical
111
112
113
114       --preview
115              requests a preview scan. The resolution used for that scan is 22
116              dpi and the scan area is the maximum allowed. The scan  mode  is
117              user selected. The default is "no".

CONFIGURATION FILE

122       The  configuration file /etc/sane.d/teco1.conf supports only one infor‐
123       mation: the device name to use (eg /dev/scanner).
124
125
126

FILES

128       /usr/lib*/sane/libsane-teco1.a
129              The static library implementing this backend.
130
131       /usr/lib*/sane/libsane-teco1.so
132              The shared library implementing this backend (present on systems
133              that support dynamic loading).
134
135
136

ENVIRONMENT

138       SANE_DEBUG_TECO1
139              If  the  library  was  compiled with debug support enabled, this
140              environment variable controls the debug level for this  backend.
141              E.g.,  a  value  of 128 requests all debug output to be printed.
142              Smaller levels reduce verbosity.
143
144
145

LIMITATIONS

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