Section: SANE Scanner Access Now Easy (5)
Updated: 14 Jul 2008
The sane-teco2 library implements a SANE (Scanner Access Now Easy) backend that provides access to some TECO SCSI flatbed scanners. This backend should be considered beta-quality software! TECO scanners are sold under various brands like Mustek, Relisys, Piotech, Primax, TRUST. This backend may or may not support yours.
The scanners that should work with this backend are:
Vendor Model TECO model status ---------------------- -------------- ----------- Mustek ScanMagic 4830S VM3575 untested Primax Jewel 4800 VM356A good Primax Profi 9600 VM6575 basic Primax Profi 19200 VM6586 good Relisys APOLLO Express 3 VM356A basic Relisys APOLLO Express 6 VM6565 good Relisys APOLLO Express 12 ? untested Relisys AVEC II S3 VM3564 good Relisys AVEC Super 3 VM3575 basic Relisys SCORPIO Pro VM6575 good Relisys SCORPIO Pro-S VM6586 untested Relisys SCORPIO Super 3 VM3575 good
For all these scanners, lineart and gray mode work well. However, most of them do not support more than a handful of resolutions in color mode. See the backend home page (under AUTHOR) for the exact status of each scanner.
Note that the untested scanner will not be directly supported. You should contact the author for that.
The TECO VM number can usually be found at the back of the scanner. It is also part of the FCC ID.
The options the backend supports can either be selected through command line options to programs like scanimage or through GUI elements in xscanimage, xsane, quiteinsane or kooka.
If you have any success with a scanner not listed here, or if you have any strange behavior, please report to the backend maintainer or to the SANE mailing list.
Valid command line options and their syntax can be listed by using
Color selects the resolution for a scan. The scanner can do only the resolutions listed.
All values with ydpi > 300 (300 x 600) or 600 (600 x 1200) result in a wrong proportion for the scan. The proportion can be adjusted with the following imagemagick command: convert -geometry (dpi/max_xdpi * 100%)x100% max_xdpi is for the vm3575 constant with 300 dpi e.g. 600dpi adjust with: convert -geometry 200
The configuration file /etc/sane.d/teco2.conf supports only one information: the device name to use (eg /dev/scanner).
The windows TWAIN driver has many more options than this SANE backend. However they are only software adjustments. This backend only implements what the scanner can support.
Plenty. Parts of this backend are still under development.
