sane-artec - SANE backend for Artec flatbed scanners
The sane-artec library implements a SANE (Scanner Access Now Easy) backend that provides access to Artec/Ultima SCSI flatbed scanners. At present, the following scanners are known to work at least partially with this backend:
:* Artec A6000C
Although this manual page is generally updated with each release, up-to-date information on new releases and extraneous helpful hints are available from the backend homepage:
The contents of the artec.conf file are a list of device names that correspond to Artec scanners. Empty lines and lines starting with a hash mark (#) are ignored. See sane-scsi?(5) on details of what constitutes a valid device name.
# artec.conf # # this is a comment. # # this line says search for any SCSI devices which are scanners and have # a vendor string of 'ULTIMA' scsi ULTIMA # # the next line forces the backend to assume the next scanner found has # the specified vendor string (useful for testing rebadged models). vendor ULTIMA # # the next line forces the backend to assume the next scanner found has # the specified model string (useful for testing rebadged models). model AT3 # # now a line that actually specifies a device. The backend is going to # assume this is an Artec/Ultima AT3 because we forced the vendor and # model above. /dev/scanner # # once we hit a scanner device line, the forced vendor and model # string are # 'forgotten', so the vendor and model for this next device will be # determined from the result of a SCSI inquiry. /dev/sge #
Some Artec scanners come with an included SCSI adapter. If your scanner came with a DTC ISA scsi cards, you can probably use it with recent (>= 2.2.0) kernels using the generic NCR5380 support. You must pass the following boot argument to the kernel: "dtc3181e=0x2c0,0"
I do not have any information on the PCI SCSI adapter included with some newer Artec scanners.

Known bugs in this release: A6000C+ users with firmware v1.92 or earlier have problems with the backend, the cause has not been determined. Sometimes the backend is not particularly robust, you can possibly lock up the SCSI bus (and/or machine) by not having patience enough when scanning. 3-channel gamma correction is not implemented and single-channel gamma correction is not totally working on models other than the AT3.
