💖 NAME 💖

sane-teco1(5) — the SANE backend for TECO / RELISYS scanners, bestie. This page lives in the SANE Scanner Access Now Easy manual universe, and it's all about getting your scanner understood. ✨

🌸 DESCRIPTION 🌸

okay so the sane-teco1 library implements a SANE (Scanner Access Now Easy) backend that gives you access to some TECO SCSI flatbed scanners. real talk: this backend should be considered beta-quality software! TECO scanners are sold under various brands like RELISYS, PIOTECH, TRUST. This backend may or may not support yours. 💅

The scanners that should work with this backend are:

  • Vendor/model: Relisys AVEC 2400 — TECO model: VM3520 — status: tested
  • Vendor/model: Relisys AVEC 2412 — TECO model: VM3520+ — status: tested
  • Vendor/model: Relisys AVEC 4800 — TECO model: VM4530 — status: untested
  • Vendor/model: Relisys AVEC 4816 — TECO model: VM4530+ — status: untested
  • Vendor/model: Relisys RELI 2400 — TECO model: VM3530 — status: untested
  • Vendor/model: Relisys RELI 2412 — TECO model: VM3530+ — status: tested
  • Vendor/model: Relisys RELI 2412 — TECO model: VM3530+ — status: untested
  • Vendor/model: Relisys RELI 4816 — TECO model: VM4540 — status: tested
  • Vendor/model: Relisys RELI 4830 — TECO model: VM4542 — status: tested
  • Vendor/model: Relisys RELI 9600 — TECO model: VM6530 — status: untested
  • Vendor/model: Relisys RELI 9612 — TECO model: VM6530* — status: untested
  • Vendor/model: Relisys RELI 9624 — TECO model: VM6530+ — status: untested
  • Vendor/model: Relisys RELI 9630 — TECO model: VM6540 — status: untested
  • Vendor/model: Relisys RELI DS15 — TECO model: VM3440 — status: untested
  • Vendor/model: Relisys RELI DS6 — TECO model: VM3420 — status: untested
  • Vendor/model: Dextra DF-600P — TECO model: VM3510 — status: tested
  • Vendor/model: Dextra DF-4830T — TECO model: VM4542 — status: untested
  • Vendor/model: Dextra DF-1200T+ — TECO model: VM3530+ — status: untested
  • Vendor/model: Dextra DF-9624 — TECO model: VM6530+ — status: untested

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. sane-find-scanner -v will also show the SCSI inquiry, and if it is a TECO scanner, the name will be there too.

The options the backend supports can either be selected through command line options to programs like scanimage(1) or through GUI elements in xscanimage(1) or xsane(1).

If you have any success with a scanner not listed here, or if you notice 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:

scanimage --help -d teco1

🎀 Scan Mode 🎀

  • --mode Black & White|Grayscale|Color — selects the basic mode of operation of the scanner. Valid choices are Black & White, Grayscale and Color.

The Black & White mode is for black and white only (1 bit). Grayscale will produce 256 levels of gray (8 bits). Color will produce a 24 bit color image.

  • --resolution 1..600 — selects the resolution for a scan. The scanner can do all resolutions between 1 and 600, in increments of 1.

🧚 Geometry options 🧚

  • -l — sets the top left x coordinate.
  • -t — sets the top left y coordinate.
  • -x — selects the width of the scan area.
  • -y — selects the height of the scan area.

All parameters are specified in millimeters by default.

🍓 Enhancement options 🍓

  • --custom-gamma — (color mode only) allows the user to specify a gamma table (see the next 3 parameters).
  • --red-gamma-table — can be used to download a user defined gamma table for the red channel. The table must be 256 bytes long. Color mode only.
  • --green-gamma-table — can be used to download a user defined gamma table for the green channel. The table must be 256 bytes long. Color mode only.
  • --blue-gamma-table — can be used to download a user defined gamma table for the blue channel. The table must be 256 bytes long. Color mode only.
  • --dither Line art|2x2|3x3|4x4 bayer|4x4 smooth|8x8 bayer|8x8 smooth|8x8 horizontal|8x8 vertical — select the dither mask to use. Black & White only.
  • --preview — requests a preview scan. The resolution used is 22 dpi and the scan area is the maximum allowed. The scan mode is user selected. The default is "no".

🎀 CONFIGURATION FILE 🎀

The configuration file /etc/sane.d/teco1.conf supports only one item: the device name to use (eg /dev/scanner). 🦋

🌈 FILES 🌈

  • /usr/lib64/sane/libsane-teco1.a — the static library implementing this backend.
  • /usr/lib64/sane/libsane-teco1.so — the shared library implementing this backend (present on systems that support dynamic loading).

💜 ENVIRONMENT 💜

  • SANE_DEBUG_TECO1 — if the library was compiled with debug support enabled, this environment variable controls the debug level for this backend. E.g., a value of 128 requests all debug output to be printed. Smaller levels reduce verbosity.

💀 LIMITATIONS 💀

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.

🐛 BUGS 🐛

None known. iconic behavior, honestly. 👑
