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:

       Additional information can be found at http://www.sane-project.org/.

       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 sane-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/x86_64-linux-gnu/sane/libsane-microtek2.a
              The static library implementing this backend.

       /usr/lib/x86_64-linux-gnu/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
