NAME
       sane-microtek2 - SANE backend for Microtek scanners with SCSI-2 command
       set

DESCRIPTION
       The sane-microtek2 library implements a SANE (Scanner Access Now	 Easy)
       backend that provides access to Microtek scanners with a SCSI-2 command
       set.  This backend can be considered alpha to beta. Some scanner models
       are reported to work well, others not. New development versions of this
       backend can be obtained from http://karstenfestag.gmxhome.de

       There exists a different backend for Microtek scanners with SCSI-1 com-
       mand set.  Refer to sane-microtek(5) for details.

       And   there   is	  work	in  progress  for  the	ScanMaker  3600.   See
       http://sourceforge.net/projects/sm3600

       At present, the following scanners are known positively	to  work  with
       this backend:

       If  you own a Microtek scanner other than the ones listed above, it may
       or may not work with SANE! Because equal scanners are sold  under  dif-
       ferent names in different countries your model may be equivalent to one
       of the above.

       The parport scanners work with the ppscsi + onscsi kernel modules.  See
       http://cyberelk.net/tim/parport/ppscsi.html     and     http://penguin-
       breeder.org/kernel/download/.


       The USB scanners work with the microtek kernel module. You may have  to
       add  the vendor and model codes to microtek.c if they aren't yet listed
       there.

       Both parport and USB scanners need the generic SCSI support,  so	 check
       if you have loaded the scsi_mod and sg modules!

       If  you	try  your  scanner for the first time keep an eye on it. If it
       gets commands that it doesn't understand the scanhead may go beyond the
       scan area.  The scanner then makes strange noises. In this case immedi-
       ately switch off the scanner or disconnect its power cable  to  prevent
       damages!

       If  your scanner is a different one than the models mentioned above and
       it is working please tell the author about it. It would be nice if  you
       add a logfile to this information (creation of the logfile: see below).

       If  your	 scanner is not working properly you also should create a log-
       file and send it to the author. He will use the information to  improve
       the backend and possibly make your scanner work.

       How to create the logfile?

       - put the line
	      "option  dump  2"	 into  your  microtek2.conf file or change the
	      existing "option dump" to "2"

       - in a terminal (bash) type
	      "export SANE_DEBUG_MICROTEK2=30" and then
	      "scanimage -l0 -t0 -x100 -y20 2>scan.log >sout.pnm"
	      You get two files: scan.log contains the	logfile	 and  sout.pnm
	      the  scanned  image  (if	there was scanned something). Zip them
	      before sending.


FRONTEND OPTIONS
       This backend dynamically enables the options for the frontend, that are
       supported  by  the scanner in dependence of the scanning-mode and other
       options.	 Not supported options are disabled.

       The following options are supported by the Microtek2-driver:

       Color, grayscale, halftone and lineart scans.

       Highlight, midtone, shadow, contrast, brightness,  exposure  time  con-
       trol,  gamma  correction, threshold (dependent of the scan mode and the
       scanner capabilities)

       Transparency media adapter, automatic document feeder

       Additional options can be enabled or  disabled  in  the	microtek2.conf
       file. See the configuration section of this manpage.


DEVICE NAMES
       This backend expects device names of the form:

	      special

       Where  special is the UNIX path-name for the special device that corre-
       sponds to the scanner.  The special device name must be a generic  SCSI
       device  or a symlink to such a device.  Under Linux, such a device name
       could be /dev/sga or /dev/sge for example.

CONFIGURATION
       The    configuration    file    for    this    backend	 resides    in
       /etc/sane.d/microtek2.conf.

       Its  contents  is  a  list  of device names that correspond to Microtek
       scanners with SCSI-2 interface. Empty lines and lines starting  with  a
       hash mark (#) are ignored.

       The  configuration  file	 may also contain options. Global options that
       are valid for all devices are placed above the  device  names.  Device-
       specific	 options  are  placed under the device name. Note that, except
       for option dump <n> and option  strip-height  <n>,  the	entry  in  the
       microtek2.conf  file  only  enables  the corresponding option for being
       showed in the frontend. There, in the  frontend,	 you  can  switch  the
       options on and off.  Currently the following options are supported:

	      option dump <n>
	      option strip-height <n>
	      option no-backtrack-option <on/off>
	      option lightlid-35 <on/off>
	      option toggle-lamp <on/off>
	      option lineart-autoadjust <on/off>
	      option backend-calibration <on/off>
	      option colorbalance-adjust <on/off>

       option  dump  <n>  enables printing of additional information about the
       SCSI commands that are sent to the scanner to stderr.  This  option  is
       primarily  useful for debugging purpose. This option has to be a global
       option and is best placed at the top of the microtek2.conf file.

       If n=1 the contents of the command  blocks  and	the  results  for  the
       INQUIRY and READ SCANNER ATTRIBUTES command are printed to stderr.

       If  n=2	the contents of the command blocks for all other SCSI commands
       are printed to stderr, too. If n=3 the contents of the gamma  table  is
       printed, too. If n=4 all scan data is additionally printed to stderr.

       The default is n=1.

       option  strip-height <n> , where <n> is a floating point number, limits
       the amount of data that is read from the scanner with one read command.
       The  unit is inch and <n> defaults to 1.0, if this option is not set in
       the configuration file. If less than <n> inch of data fit into the SCSI
       buffer, then the smaller value is used and this option has no effect.

       If  your	 system	 has a big SCSI buffer and you want to make use of the
       whole buffer, increase the value for <n>. For example, if <n> is set to
       14.0,  no  restrictions	apply  for scanners with a letter, legal or A4
       sized scan area.

       The following options enable or disable additional frontend options. If
       an option is set to <on> an appropriate option will appear in the fron-
       tend.

       option no-backtrack-option <on/off> prevents the scanner head from mov-
       ing  backwards between the read commands.  This speeds up scanning. Try
       it.

       option lightlid-35 <on/off> If you  use	the  LightLid-35  transparency
       adapter	you get an advanced option which switches off the flatbed lamp
       during the scan.

       option toggle-lamp <on/off> You get a button in the frontend where  you
       can switch on and off the flatbed lamp.

       option  lineart-autoadjust  <on/off> You can tell the backend to try to
       determine a good value for the lineart threshold.

       option backend-calibration <on/off> Some scanners (e.g.	Phantom	 330CX
       and  636CX)  need  to have calibrated the data by the backend. Try this
       option if you see vertical stripes in your pictures.

       option colorbalance-adjust <on/off> Some scanners (e.g.	Phantom	 330CX
       and  636CX) need to have corrected the color balance. If this option is
       enabled you get advanced options where you can balance the colors.  And
       you will have a button to use the values that the firmware of the scan-
       ner provides.

       A sample configuration file is shown below:

	      option dump 1
	      option strip-height 1.0
	      /dev/scanner
	      option no-backtrack-option on
	      # this is a comment
	      /dev/sge
	      option lightlid-35 on

       This backend also supports the  new  configuration  file	 format	 which
       makes  it  easier  to detect scanners under Linux. If you have only one
       scanner it would be best to use the following  configuration  file  for
       this backend:

	      option dump 1
	      option strip-height 14.0
	      option no-backtrack-option on
	      option backend-calibration on
	      option lightlid-35 on
	      option toggle-lamp on
	      option lineart-autoadjust on
	      option colorbalance-adjust off
	      scsi * * Scanner

       In this case all SCSI-Scanners should be detected automatically because
       of the

       scsi * * Scanner

       line.


FILES
       /etc/sane.d/microtek2.conf
	      The backend configuration file.

       /usr/lib*/sane/libsane-microtek2.a
	      The static library implementing this backend.

       /usr/lib*/sane/libsane-microtek2.so
	      The shared library implementing this backend (present on systems
	      that support dynamic loading).

ENVIRONMENT
       SANE_DEBUG_MICROTEK2
	      If  the  library	was  compiled with debug support enabled, this
	      environment variable controls the debug level for this  backend.
	      E.g.,  a	value  of 255 requests all debug output to be printed.
	      Smaller levels reduce verbosity. To see error messages on stderr
	      set  SANE_DEBUG_MICROTEK2 to 1 (Remark: The whole debugging lev-
	      els should be better revised).
	      E.g. just say:
	      export SANE_DEBUG_MICROTEK2=128
