sane-artec_eplus48u - SANE backend for the scanner Artec E+ 48U and re-
The sane-artec_eplus48u library implements a SANE (Scanner Access Now
Easy) backend that provides access to several USB flatbed scanners us-
ing the GT6816 chipset like the Artec E+ 48U. These scanners have a
contact image sensor (CIS) and an USB interface.
A complete list of supported devices can be found on
This is ALPHA software. Especially if you test new or untested scan-
ners, keep your hand at the scanner's plug and unplug it, if the head
bumps at the end of the scan area.
If you own a scanner other than the ones mentioned on the list that
works with this backend, please let us know this by sending the scan-
ner's exact model name and the USB vendor and product ids (e.g. from
/proc/bus/usb/devices, sane-find-scanner or syslog) to me. Even if the
scanner's name is only slightly different from the models mentioned
above, please let me know.
If libusb-0.1.6 or later is installed, this section can be skipped. The
scanner should be found by sane-find-scanner without further actions.
For setting permissions and general USB information look at
When you are using the scanner module, a Linux kernel 2.4.12 or newer
You need a firmware file for your scanner. That's a small file contain-
ing software that will be uploaded to the scanner's memory. For the
scanners mentioned above, it's usually named Artec48.usb or 1200.usb.
You can find it on the installation CD that was provided by the manu-
facturer, normally in the directory Win98, WinMe or similar. If the
Windows-driver is installed on your computer, then you can also find
the firmware file under c:\windows\system32\drivers.
The contents of the artec_eplus48u.conf file is a list of usb lines
containing vendor and product ids that correspond to USB scanners. The
file can also contain option lines. Empty lines and lines starting
with a hash mark (#) are ignored. The scanners are autodetected by usb
vendor_id product_id statements which are already included into
artec_eplus48u.conf . "vendor_id" and "product_id" are hexadecimal
numbers that identify the scanner.
Every usb section can have additional options
The path to the firmware file. This option is required.
These are the default gamma values. If you set the "Defaults"
option with a frontend, then the gamma options are reset to the
values specified here.
These are the default values for offset and exposure time. You
can e.g. change them to speed up calibration, if you don't want
to save the calibration data to disk.
modelString E+ 48U
By default, the scanner is reported as "Artec E+ 48U". If you
don't like this, e.g. because you have an Tevion MD 9693, then
change the options accordingly.
The backend configuration file (see also description of
The static library implementing this backend.
The shared library implementing this backend (present on systems
that support dynamic loading).
This environment variable specifies the list of directories that
may contain the configuration file. Under UNIX, the directories
are separated by a colon (`:'), under OS/2, they are separated
by a semi-colon (`;'). If this variable is not set, the config-
uration file is searched in two default directories: first, the
current working directory (".") and then in /usr/lo-
cal/etc/sane.d. If the value of the environment variable ends
with the directory separator character, then the default direc-
tories are searched after the explicitly specified directories.
For example, setting SANE_CONFIG_DIR to "/tmp/config:" would re-
sult in directories "tmp/config", ".", and "/usr/lo-
cal/etc/sane.d" being searched (in this order).
If the library was compiled with debug support enabled, this en-
vironment variable controls the debug level for this backend.
Higher debug levels increase the verbosity of the output.
Example: export SANE_DEBUG_ARTEC_EPLUS48U=3
This backend is based on the gt68xx test-program written by Sergey
Vlasov, Andreas Nowack, and David Stevenson. Thanks to everyone who
tested the backend or reported bugs.
This man page is based on man sane-gt68xx, written by Henning Meier-
This backend has been tested on Linux only. If you are using it on a
different platform, please contact us.
Interpolation with 1200 dpi is weak.
Support for buttons is missing due to missing support in SANE.
