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

          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 command 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 scan-
          ners 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 and

          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 scan-
          head 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 (cre-
          ation of the logfile: see below).

          If your scanner is not working properly you also should cre-
          ate 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 some-
               thing). Zip them before sending.

          This backend dynamically enables the options for the fron-
          tend, that are supported by the scanner in dependence of the
          scanning-mode and other options.  Not supported options are

     sane-microtek2(5)         (13 Jul 2008)         sane-microtek2(5)

          The following options are supported by the sane-microtek2

          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

          This backend expects device names of the form:


          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.

          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

               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 pur-
          pose. 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 num-
          ber, 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

     Page 4                       Plan 9             (printed 5/24/22)

          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
               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 automati-
          cally because of the

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