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(1) or through GUI elements in
31       xscanimage(1) or xsane(1).
32
33       If you have any success with a scanner  not  listed  here,  or  if  you
34       notice any strange behavior, please report to the backend maintainer or
35       to the SANE mailing list.

OPTIONS

39       Valid command line options and their syntax can be listed by using:
40
41              scanimage --help -d teco3
42
43
44       Scan Mode
45
46
47       --mode Black & White|Grayscale|Color
48              Selects the basic mode of operation of the scanner.  The Black &
49              White mode is black and white only (1 bit).  Grayscale will pro‐
50              duce 256 levels of gray (8 bits).  Color will produce  a  24-bit
51              color image.
52
53
54       --resolution 1..1200
55              Selects  the resolution for a scan. The scanner can do all reso‐
56              lutions between 1 and 1200, in increments of 1.
57
58
59       --preview
60              Requests a preview scan. The resolution used for that scan is 22
61              dpi  and  the scan area is the maximum allowed. The scan mode is
62              user selected. The default is "no".
63
64
65       Geometry options
66
67
68       -l -t -x -y
69              Control the scan area: -l sets the top left x coordinate, -t the
70              top left y coordinate, -x selects the width and -y the height of
71              the scan area.  All parameters are specified in  millimeters  by
72              default.
73
74

OPTIONS FOR COLOR MODE ONLY

76       --custom-gamma
77              Allows the user to specify a gamma table (see the next 3 parame‐
78              ters).
79
80
81       --red-gamma-table
82              Can be used to download a user defined gamma table for  the  red
83              channel. The table must be 1024 bytes long.
84
85
86       --green-gamma-table
87              Can be used to download a user defined gamma table for the green
88              channel. The table must be 1024 bytes long.
89
90
91       --blue-gamma-table
92              Can be used to download a user defined gamma table for the  blue
93              channel. The table must be 1024 bytes long.

CONFIGURATION FILE

98       The  configuration  file /etc/sane.d/teco3.conf supports only one item:
99       the device name to use (eg /dev/scanner).
100
101
102

FILES

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

ENVIRONMENT

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

121

LIMITATIONS

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