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 command 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 different 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 immediately 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 logfile 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 control, 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 corresponds 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 frontend.

       option  no-backtrack-option  <on/off>  prevents  the  scanner  head  from moving 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 scanner 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/arch_triplet/sane/libsane-microtek2.a
              The static library implementing this backend.

       /usr/lib/arch_triplet/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 levels should  be
              better revised).
              E.g. just say:
              export SANE_DEBUG_MICROTEK2=128
