Backend for Artec/Ultima Scanners

If you own a Artec scanner other than the ones listed above, it may work with SANE. It depends on the informations the scanner returns to the artec backend. If you know the model, you can insert an entry into the cap_data structure with appropriate information for your scanner and give that a test. I suggest you hold one hand on the power-button of the scanner while you try the first scans!

The BlackWidow BW4800SP is a rebadged Artec/Ultima AT3 model scanner with an empty SCSI-ID string. The backend attempts to detect this and acts as if an AT3 was found. The Plustek OpticPRO 19200S is actually a rebadged Artec AM12S scanner with an empty SCSI-ID string. The backend attempts to detect this and acts as if an AM12S was found.

Backend Source

• Latest working :-) code (v0.5.14) as of 02/20/2000 21:48 EST (make sure you get both files). artec.c artec.h
  • 02/20/2000 - Set "Negative" option to inactive for greyscale and color modes for the A6000C as it appears to not support negating those modes.
  • 02/19/2000 - Fixed bug which was turning Contrast OFF at startup instead of Threshold.
  • 02/11/2000 - Added back in code to support brightness on the A6000C model. Bug-fix to ADF & Transparency code. Fixed bug that caused invalid options to display when first using backend, non-color options were showing when color mode is the default.
  • 02/08/2000 - Removed ARTEC_FLAG_MONO_ADJUST and related functions since they are no longer needed since all 1bpp scans are being forced to scan a full byte's worth of bits eliminating the need for the slow bit offset/buffer function.
  • 01/30/2000 - Eliminated a call to wait_ready() in the attach() function as it appears to cause problems with some AT12 models and doesn't appear it's needed according to the docs. This doesn't appear to have had any negative effect on my AT3. Removed ARTEC_FLAG_1BPP_BYTE_ALIGN and if statement that checked this flag since it does not appear to be needed anymore since new version with this flag disabled has been reported as successfully working on both the AM12S and AT12 models.
  • 01/26/2000 - Commented out ARTEC_FLAG_1BPP_BYTE_ALIGN flag for AT12 and AM12S since this should be handled by previous bugfix that always sets width to fill a full byte when in 1bpp modes. This should fix the problem causing lineart and halftone modes to coredump at the end of a scan.
  • 01/25/2000 - Another change/bugfix to the line offset calculation code. I think it was broken with recent changes. Change to starting position calculation to take into account the line offset. Disabled brightness option since the documentation says that it is not implemented in hardware and must be implemented in software. Disabled halftone pattern selection for AM12S since docs say it not supported.
  • 01/24/2000 - Bug-fixes to hopefully get AM12S and AT12 working in 1bpp modes (lineart and halftone). This fix should also help in speeding up the A6000C in those modes if it works as intended.
  • 01/21/2000 - Added code to detect Plustek OpticPRO 19200S scanner (rebadged Artec AM12S). Applied changes to fix line offset and start scan problems with Artec AM12S and Plustek 19200S scanners in color mode. Added options to support pixel averaging and line edge enhancement on AT12 models. Reworked sense handler to only check sense bits/bytes which are applicable for a particular model, believe this was causing problems when reserved data wasn't necessarily set to '0' in scanner but was being checked by sense handler.
  • 12/14/1999 - Applied patch from David Leadbetter to fix a few bugs and add in initial support for Transparency adapter and ADF (let me know if this works or doesn't work if you have either of these). Also a couple code changes to better support the AM12S and attempt to enable single-channel gamma correction on the AT12 and AM12S models.
  • 11/16/1999 - Fixed bug in software calibration code which would sometimes do RGB calibration on a mono scan. Also merged in patch from David Leadbetter fixing a couple minor bugs in A6000C in 1bpp modes.
  • 10/30/1999 - Fixed bug in gamma correction for AT3 & A6000C PLUS models. It only showed up on certain scanners (like mine).
  • 10/29/1999 - Added changes by David Leadbetter relating to A6000C 3-pass model. Some modes working.
  • 7/24/1999 - Added Software Quality Calibration for AT3 & A6000C PLUS scanners.
  • 7/24/1999 - Changed code so hardware quality calibration is performed in sane_init() function when scanner is first opened. This makes more sense than calibrating when starting to scan because calibration should be done with the scanner empty. Calibration can be performed at every scan by now checking the "Calibrate Every Scan" option.
  • 7/24/1999 - Enabled use of Gamma correction for A6000C PLUS scanners by uncommenting in source code.
  • 7/22/1999 - Fixed problem with "negative" actually being "positive". Image now appears correct when scanning in lineart and halftone modes.
  • 7/19/1999 - Fixed problem with v0.4 driver where it would treat an A6000C PLUS model scanner as a plain A6000C, causing distorted scans and possible lockups.

Other Info:

• Scsi models
• A6000C commands (still needed) (this scanner seems to be different than the A6000C Plus enough to cause problems in the driver).
• AT3 & A6000C Plus commands. .gz
• AT6 commands (still needed, hint hint hint).
• AT12 commands..gz
• AM12S commands..gz
• Parallel Port models
  There are 2 different programs being worked on for supporting the AS6E parallel port scanner. Eugene Weiss is currently working on a command line program that runs under Linux. Information on this project is available at http://as6edriver.sourceforge.net. Luigi Rizzo's webpage http://www.iet.unipi.it/~luigi/FreeBSD.html contains a version he is working on under FreeBSD. Michael Katz-Hyman has also emailed instructions for getting the AS6E to work under Wine.
• AS6E command documentation.
• Microsoft Word .doc file. .gz .zip
• Postscript. .gz
• AS6E command-line program submitted by Moritz Braun & Luigi Rizzo. I've received reports that this has problems with 2.2.x version of the Linux kernel, if you have success with this on 2.2.x kernels, please let me know. I have heard success reports about some of the 2.3.x kernels. Since Eugene is more actively working on his program, you should go to his webpage for the latest version.
• May 16, 1999 version. ppscan990516.c
• April 20, 1999 version. ppscanimage_19990420.c
• Usage: "ppscanimage mode res x0 y0 x1 y1 > out.pnm"
  where:
  mode = 'g' or 'c' for greyscale or color
  res is one of 50,100,200,300 (dpi)
  x0,y0,x1,y1 are the upper left and lower right corners (in pixels) that will be scanned.
