.SH NAME
|
|
sane\-artec_eplus48u \- SANE backend for the scanner Artec E+ 48U and re-badged models
|
|
.SH DESCRIPTION
|
|
The
|
|
.B sane\-artec_eplus48u
|
|
library implements a SANE (Scanner Access Now Easy) backend that provides
|
|
access to several USB flatbed scanners using the GT6816 chipset like the Artec E+ 48U.
|
|
These scanners have a contact image sensor (CIS) and an USB interface.
|
|
.PP
|
|
A complete list of supported devices can be found on
|
|
.IR http://www.sane\-project.org/sane\-supported\-devices.html .
|
|
.PP
|
|
This is ALPHA software. Especially if you test new or untested scanners, keep
|
|
your hand at the scanner's plug and unplug it, if the head bumps at the end of
|
|
the scan area.
|
|
.PP
|
|
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 scanner'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.
|
|
.PP
|
|
.SH KERNEL ISSUES
|
|
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 sane\-usb(5).
|
|
.PP
|
|
When you are using the scanner module, a Linux kernel 2.4.12 or newer is
|
|
required.
|
|
|
|
.SH FIRMWARE FILE
|
|
You need a firmware file for your scanner. That's a small file containing
|
|
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 manufacturer, 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.
|
|
.SH CONFIGURATION
|
|
The contents of the
|
|
.I 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
|
|
.I usb vendor_id product_id
|
|
statements which are already included into
|
|
.I artec_eplus48u.conf .
|
|
"vendor_id" and "product_id" are hexadecimal numbers that identify the
|
|
.B scanner.
|
|
.PP
|
|
Every usb section can have additional options
|
|
.TP
|
|
.B artecFirmwareFile @DATADIR@/sane/artec_eplus48u/Artec48.usb
|
|
The path to the firmware file. This option is required.
|
|
.TP
|
|
.B redGamma 1.0
|
|
.TP
|
|
.B greenGamma 1.0
|
|
.TP
|
|
.B blueGamma 1.0
|
|
.TP
|
|
.B masterGamma 1.9
|
|
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.
|
|
.TP
|
|
.B redOffset 0x28
|
|
.TP
|
|
.B greenOffset 0x2f
|
|
.TP
|
|
.B blueOffset 0x2f
|
|
.TP
|
|
.B redExposure 0xa7
|
|
.TP
|
|
.B greenExposure 0x116
|
|
.TP
|
|
.B blueExposure 0xdc
|
|
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.
|
|
.TP
|
|
.B vendorString "Artec"
|
|
.TP
|
|
.B 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.
|
|
.SH FILES
|
|
.TP
|
|
.I /usr/local/etc/sane.d/artec_eplus48u.conf
|
|
The backend configuration file (see also description of
|
|
.B SANE_CONFIG_DIR
|
|
below).
|
|
.TP
|
|
.I /usr/local/lib/sane/libsane\-artec_eplus48u.a
|
|
The static library implementing this backend.
|
|
.TP
|
|
.I /usr/local/lib/sane/libsane\-artec_eplus48u.so
|
|
The shared library implementing this backend (present on systems that
|
|
support dynamic loading).
|
|
.SH ENVIRONMENT
|
|
.TP
|
|
.B SANE_CONFIG_DIR
|
|
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 configuration file
|
|
is searched in two default directories: first, the current working
|
|
directory (".") and then in /usr/local/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
|
|
.B SANE_CONFIG_DIR
|
|
to "/tmp/config:" would result in directories "tmp/config", ".", and
|
|
"/usr/local/etc/sane.d" being searched (in this order).
|
|
.TP
|
|
.B SANE_DEBUG_ARTEC_EPLUS48U
|
|
If the library was compiled with debug support enabled, this
|
|
environment variable controls the debug level for this backend. Higher
|
|
debug levels increase the verbosity of the output.
|
|
|
|
Example:
|
|
export SANE_DEBUG_ARTEC_EPLUS48U=3
|
|
|
