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


        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
        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
        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     and     http://penguin-
        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
        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
        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.
        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.
        This backend expects device names of the form:
        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.


        The    configuration    file    for    this    backend    resides    in
        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‐
        option no-backtrack-option <on/off> prevents the scanner head from mov‐
        ing backwards between the read commands.  This speeds up scanning.  Try
        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
               option no-backtrack-option on
               # this is a comment
               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


               The backend configuration file.
               The static library implementing this backend.
               The shared library implementing this backend (present on systems
               that support dynamic loading).


               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
        sane-scsi(5), sane(7)
