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 or through GUI elements in
45 xscanimage, xsane, quiteinsane or kooka.
46 If you have any success with a scanner not listed here, or if you have
48 any strange behavior, please report to the backend maintainer or to the
49 SANE mailing list.
50 Valid command line options and their syntax can be listed by using
52 scanimage --help -d teco2
53 Scan Mode
56 --mode selects the basic mode of operation of the scanner valid choices
59 are Lineart , Gray and Color The Lineart mode is black and white
60 only (1 bit). Gray mode will produce 256 levels of gray (8
61 bits). Color will produce a 24 bits color image.
62 --resolution
65 Lineart and Gray selects the resolution for a scan. The scanner
66 can do all resolutions between 1 and 600, in increments of 1.
67 Color selects the resolution for a scan. The scanner can do only
70 the resolutions listed.
71 All values with ydpi > 300 (300 x 600) or 600 (600 x 1200)
73 result in a wrong proportion for the scan. The proportion can be
74 adjusted with the following imagemagick command: convert -geome‐
75 try (dpi/max_xdpi * 100%)x100% max_xdpi is for the vm3575 con‐
76 stant with 300 dpi e.g. 600dpi adjust with: convert -geometry
77 200%x100%
78 Geometry options
81 -l -t -x -y
84 control the scan area: -l sets the top left x coordinate, -t the
85 top left y coordinate, -x selects the width and -y the height of
86 the scan area. All parameters are specified in millimeters by
87 default.
88 Enhancement options
92 --custom-gamma (no custom gamma option for the VM3564 and VM356A)
95 (color mode only) allows the user to specify a gamma table (see
96 the next 3 parameters).
97 --red-gamma-table
100 (color mode only) can be used to download a user defined gamma
101 table for the red channel. The table must be 256 bytes long.
102 --green-gamma-table
105 (color mode only) can be used to download a user defined gamma
106 table for the green channel. The table must be 256 bytes long.
107 --blue-gamma-table
110 (color mode only) can be used to download a user defined gamma
111 table for the blue channel. The table must be 256 bytes long.
112 --white-level-r
115 (VM3564, VM356A, VM3575 and VM6575 only) Selects what red radi‐
116 ance level should be considered "white", when scanning some
117 sheets by changing the calibration value loaded into the scan‐
118 ner. Scale 0..64 in steps of 1.
119 --white-level-g
122 (VM3564, VM356A, VM3575 and VM6575 only) Selects what green
123 radiance level should be considered "white", when scanning some
124 sheets by changing the calibration i value loaded into the scan‐
125 ner. Scale 0..64 in steps of 1.
126 --white-level-b
129 (VM3564, VM356A, VM3575 and VM6575 only) Selects what blue radi‐
130 ance level should be considered "white", when scanning some
131 sheets by changing the calibration value loaded into the scan‐
132 ner. Scale 0..64 in steps of 1.
133 --preview
136 requests a preview scan. The resolution used for that scan is 50
137 dpi (for VM356A and VM6575 75 dpi) and the scan area is the max‐
138 imum allowed. The scan mode is user selected. The default is
139 "no".
140
144 The configuration file /etc/sane.d/teco2.conf supports only one infor‐
145 mation: the device name to use (eg /dev/scanner).
146
150 /usr/lib*/sane/libsane-teco2.a
151 The static library implementing this backend.
152 /usr/lib*/sane/libsane-teco2.so
154 The shared library implementing this backend (present on systems
155 that support dynamic loading).
156
160 SANE_DEBUG_TECO2
161 If the library was compiled with debug support enabled, this
162 environment variable controls the debug level for this backend.
163 E.g., a value of 128 requests all debug output to be printed.
164 Smaller levels reduce verbosity.
165 SANE_TECO2_CAL_ALGO
167 Either 0 or 1. Selects the algorithm for the calibration. A
168 value of 1 seems to give better scans on the VM356A, VM3575.
169 Feedback on it is welcome. For VM3564, VM356A, VM3575, VM6575
170 default 1. For other supported types default 0.
171
175 The windows TWAIN driver has many more options than this SANE backend.
176 However they are only software adjustments. This backend only imple‐
177 ments what the scanner can support.
178
182 Plenty. Parts of this backend are still under development.
