sane-artec(5) SANE Scanner Access Now Easy sane-artec(5)
NAME
sane-artec - SANE backend for Artec flatbed scanners
DESCRIPTION
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
* Artec A6000C PLUS
* Artec ViewStation AT3
* BlackWidow BW4800SP (rebadged Artec AT3)
* Artec ViewStation AT6
* Artec ViewStation AT12
* Artec AM12S
* Plustek 19200S (rebadged Artec AM12S)
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:
http://www4.infi.net/~cpinkham/sane.
CONFIGURATION
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 consti-
tutes a valid device name.
Sample file:
# 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

SCSI ADAPTER TIPS
Some Artec scanners come with an included SCSI adapter. If your scan-
ner 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.
FILES
/etc/sane.d/artec.conf
The backend configuration file (see also description of
SANE_CONFIG_DIR below).
/usr/lib/x86_64-linux-gnu/sane/libsane-artec.a
The static library implementing this backend.
/usr/lib/x86_64-linux-gnu/sane/libsane-artec.so
The shared library implementing this backend (present on systems
that support dynamic loading).
ENVIRONMENT
SANE_CONFIG_DIR
This environment variable specifies the list of directories that
may contain the configuration file. On *NIX systems, the direc-
tories are separated by a colon (`:'), under OS/2, they are sep-
arated by a semi-colon (`;'). If this variable is not set, the
configuration file is searched in two default directories:
first, the current working directory (".") and then in
/etc/sane.d. If the value of the environment variable ends with
the directory separator character, then the default directories
are searched after the explicitly specified directories. For
example, setting SANE_CONFIG_DIR to "/tmp/config:" would result
in directories tmp/config, ., and /etc/sane.d being searched (in
this order).
SANE_DEBUG_ARTEC
If the library was compiled with debug support enabled, this en-
vironment 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: SANE_DEBUG_ARTEC values:
Number Remark
0 print important errors
1 print errors
2 print sense
3 print warnings
4 print scanner-inquiry
5 print information
6 print less important information
7 print major called procedures
8 print all called procedures
9 print procedure info/data messages
10 print called sane-init-routines
11 print called sane-procedures
12 print sane infos
13 print sane option-control messages
50 print verbose data/debug messages
== 100 print software RGB calibration data
== 101 print raw data from scanner to artec.data.raw file
== 128 print out all messages
Example: export SANE_DEBUG_ARTEC=13
BUGS
Known bugs in this release: A6000C+ users with firmware v1.92 or ear-
lier 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.
