sane-artec_eplus48u(5)		     SANE		sane-artec_eplus48u(5)

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  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.

       A  complete  list of supported devices can be found on http://www.sane-
       project.org/sane-supported-devices.html.

       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.

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 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.

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			  /system/resources/sane-back‐
       ends/1.0.18/share/sane/artec_eplus48u/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

AUTHOR
       Michael Herder
       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 us.

       Interpolation with 1200 dpi is weak.

       Support for buttons is missing due to missing support in SANE.

       Please	 contact    us	 if   you   find   a   bug:   http://www.sane-
       project.org/bugs.html.
