6 sane-teco2 - SANE backend for TECO / RELISYS scanners
7
9 The sane-teco2 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 Mustek, Relisys, Piotech, Primax, TRUST.
13 This backend may or may not support yours.
14 The scanners that should work with this backend are:
16 Vendor Model TECO model status
18 --------------------------- -------------- -----------
19 Mustek ScanMagic 4830S VM3575 untested
20 Primax Jewel 4800 VM356A good
21 Primax Profi 9600 VM6575 basic
22 Primax Profi 19200 VM6586 good
23 Relisys APOLLO Express 3 VM356A basic
24 Relisys APOLLO Express 6 VM6565 good
25 Relisys APOLLO Express 12 ? untested
26 Relisys AVEC II S3 VM3564 good
27 Relisys AVEC Super 3 VM3575 basic
28 Relisys SCORPIO Pro VM6575 good
29 Relisys SCORPIO Pro-S VM6586 untested
30 Relisys SCORPIO Super 3 VM3575 good
31 For all these scanners, lineart and gray mode work well. However, most
33 of them do not support more than a handful of resolutions in color
34 mode. See the backend home page (under AUTHOR) for the exact status of
35 each scanner.
36 Note that the untested scanner will not be directly supported. You
38 should contact the author for that.
39 The TECO VM number can usually be found at the back of the scanner. It
41 is also part of the FCC ID.
42 The options the backend supports can either be selected through command
44 line options to programs like scanimage(1) or through GUI elements in
45 xscanimage(1), xsane(1), quiteinsane(1) or kooka(1).
46 If you have any success with a scanner not listed here, or if you no‐
48 tice any strange behavior, please report to the backend maintainer or
49 to the SANE mailing list.
50
53 Valid command line options and their syntax can be listed by using:
54 scanimage --help -d teco2
56 Scan Mode
59 --mode Lineart|Gray|Color
62 selects the basic mode of operation of the scanner. The Lineart
63 mode is black and white only (1 bit). Gray mode will produce
64 256 levels of gray (8 bits). Color will produce a 24 bits color
65 image.
66 --resolution 1..600
69 Selects the resolution for a scan. The scanner can do all reso‐
70 lutions between 1 and 600, in increments of 1, for Lineart and
71 Gray. For Color, a restricted set of resolutions are available.
72 Note: All values with ydpi > 300 (300 x 600) or 600 (600 x 1200)
74 result in a wrong proportion for the scan. The proportion can be
75 adjusted with the following convert(1) command from imagemagick:
76 convert -geometry (dpi/max_xdpi * 100%)x100%
77 max_xdpi is for the vm3575 constant with 300 dpi e.g. 600dpi ad‐
78 just with: convert -geometry 200%x100%
79 --preview
82 requests a preview scan. The resolution used for that scan is 50
83 dpi (for VM356A and VM6575 75 dpi) and the scan area is the max‐
84 imum allowed. The scan mode is user selected. The default is
85 "no".
86 Geometry options
89 -l, -t, -x, -y
92 Control the scan area: -l sets the top left x coordinate, -t the
93 top left y coordinate, -x selects the width and -y the height of
94 the scan area. All parameters are specified in millimeters by
95 default.
96 Enhancement options
100 --custom-gamma (no custom gamma option for the VM3564 and VM356A)
103 (color mode only) allows the user to specify a gamma table (see
104 the next 3 parameters).
105
108 These options are valid for scan mode Color only.
109 --red-gamma-table
112 Can be used to download a user defined gamma table for the red
113 channel. The table must be 256 bytes long.
114 --green-gamma-table
117 Can be used to download a user defined gamma table for the green
118 channel. The table must be 256 bytes long.
119 --blue-gamma-table
122 Can be used to download a user defined gamma table for the blue
123 channel. The table must be 256 bytes long.
124
127 These options are only available for VM3564, VM356A, VM3575 and VM6575
128 models.
129 --white-level-r 0..64
131 Selects what red radiance level should be considered "white",
132 when scanning some sheets by changing the calibration value
133 loaded into the scanner. Scale 0..64 in steps of 1.
134 --white-level-g 0..64
137 Selects what green radiance level should be considered "white",
138 when scanning some sheets by changing the calibration value
139 loaded into the scanner. Scale 0..64 in steps of 1.
140 --white-level-b 0..64
143 Selects what blue radiance level should be considered "white",
144 when scanning some sheets by changing the calibration value
145 loaded into the scanner. Scale 0..64 in steps of 1.
146
150 The configuration file /etc/sane.d/teco2.conf supports only one item:
151 the device name to use (eg /dev/scanner).
152
156 /usr/lib64/sane/libsane-teco2.a
157 The static library implementing this backend.
158 /usr/lib64/sane/libsane-teco2.so
160 The shared library implementing this backend (present on systems
161 that support dynamic loading).
162
166 SANE_DEBUG_TECO2
167 If the library was compiled with debug support enabled, this en‐
168 vironment variable controls the debug level for this backend.
169 E.g., a value of 128 requests all debug output to be printed.
170 Smaller levels reduce verbosity.
171 SANE_TECO2_CAL_ALGO
173 Either 0 or 1. Selects the algorithm for the calibration. A
174 value of 1 seems to give better scans on the VM356A, VM3575.
175 Feedback on it is welcome. For VM3564, VM356A, VM3575, VM6575
176 default 1. For other supported types default 0.
177
181 The windows TWAIN driver has many more options than this SANE backend.
182 However they are only software adjustments. This backend only imple‐
183 ments what the scanner can support.
184
188 Plenty. Parts of this backend are still under development.
