NAME
sane-artec_eplus48u - SANE backend for the scanner Artec E+ 48U and re-
badged models
DESCRIPTION
The sane-artec_eplus48u library implements a SANE (Scanner Access Now
Easy) backend that at present provides access to the USB flatbed scan-
ners
Artec E+ 48U,
Tevion MD 9693,
Medion MD 9693,
Medion MD 9705 and
Trust Easy Webscan 19200.
These scanners have a contact image sensor (CIS) and an USB interface.
VendorID: 0x05d8
ProductID: 0x4003
The Trust Easy Webscan 19200 is an exception. It's ProductID is 0x4006.
More details can be found on http://www.angelfire.com/linux/crapsite/.
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 listed above that works with
this backend, please let me 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.
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).
When you are using the scanner module, a Linux kernel 2.4.12 or newer
is required.
FIRMWARE FILE
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. You can find
it on the installation CD that was provided by the manufacturer, nor-
mally 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.
CONFIGURATION
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
artecFirmwareFile <path>/Artec48.usb
The path to the firmware file. This option is required.
redGamma 1.0
greenGamma 1.0
blueGamma 1.0
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.
redOffset 0x28
greenOffset 0x2f
blueOffset 0x2f
redExposure 0xa7
greenExposure 0x116
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.
vendorString Artec
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.
FILES
/usr/local/etc/sane.d/artec_eplus48u.conf
The backend configuration file (see also description of
SANE_CONFIG_DIR below).
/usr/local/lib/sane/libsane-artec_eplus48u.a
The static library implementing this backend.
/usr/local/lib/sane/libsane-artec_eplus48u.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. 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/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 directo-
ries. For example, setting SANE_CONFIG_DIR to "/tmp/config:"
would result in directories "tmp/config", ".", and
"/usr/local/etc/sane.d" being searched (in this order).
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

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-
Geinitz.
BUGS
This backend has been tested on Linux only. If you are using it on a
different platform, please contact me.
Interpolation with 1200 dpi is weak.
Support for buttons is missing due to missing support in SANE.
