       sane-microtek - SANE backend for Microtek scanners


       The  sane-microtek  library  implements  a  SANE  (Scanner  Access  Now Easy) backend that
       provides access to the "second generation" Microtek scanners.  At present,  the  following
       hardware is known to work with this backend:

              Microtek ScanMaker E2, E3, E6
              Microtek ScanMaker II, IIG, IIHR, IISP, III
              Microtek ScanMaker 35t, 35t+, 45t
              Microtek ScanMaker 600GS, 600ZS (see bug notes)
              Agfa StudioScan
              Agfa StudioScan II, StudioScan IIsi
              Agfa Arcus II (but not the "Arcus")
              Agfa DuoScan (preliminary)
              Vobis "Highscreen Realscan"
              Microtek Color PageWiz (preliminary)

              Transparent Media Adapter
              Document AutoFeeder

       The  driver  supports  line  art, halftone, 8bpp gray, and 24bpp color scans at normal and
       "expanded" resolutions (i.e. 1200x1200 on an E6),  fast  scans  for  color  previews,  and
       downloadable gamma tables.

       The supported scanners are all SCSI scanners.  However, some parallel port models may work
       (under Linux), if they use a parport->scsi chip, and  if  you  can  find  a  scsi->parport
       driver.  This is known to be the case for the Color PageWiz.

       The driver does not support the newest Microtek scanners, such as the V330 and V660, which
       use a new  and  very  different  SCSI-II  command  set.   For  those,  try  the  alternate
       microtek2(5)  backend.   Most  non-SCSI  scanners  would  use  the  new command set.  Most
       scanners newer than the Scanmaker E6 would use the new command set.

       If you own a Microtek scanner other than the ones listed above, tell us what  happens  ---
       see the BUGS section at the end of this document.

       Although  this  manual page is generally updated with each release, up-to-date information
       on new releases and extraneous helpful hints are available from the backend homepage:



       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 contents of the microtek.conf file is a  list  of  device  names  that  correspond  to
       Microtek  scanners.   Empty  lines and lines starting with a hash mark (#) are ignored.  A
       sample configuration file is shown below:

              # this is a comment

       The configuration file  may  also  contain  the  special  tokens  norealcal  or  noprecal.
       norealcal  will  disable the use of magic, undocumented scanner calibration commands which
       are known to work on the E6, but may not work with other models.   noprecal  will  disable
       logic  which  tries  to  avoid  scanner  precalibration.   This logic would only have been
       activated if the magic calibration code was turned off.


              The backend configuration file (see also description of SANE_CONFIG_DIR below).

              The static library implementing this backend.

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


              This  environment  variable  specifies the list of directories that may contain the
              configuration file.  On *NIX systems, the directories  are  separated  by  a  colon
              (`:'),  under  OS/2, they are separated by a semi-colon (`;').  If this variable is
              not set, the configuration file is searched in two default directories: first,  the
              current  working  directory  (".")  and  then  in /etc/sane.d.  If the value of the
              environment variable ends with the directory separator character, then the  default
              directories  are searched after the explicitly specified directories.  For example,
              setting SANE_CONFIG_DIR to "/tmp/config:" would result in  directories  tmp/config,
              ., and /etc/sane.d being searched (in this order).

              If  the  library  was  compiled  with  debugging  support enabled, this environment
              variable controls the debug level for  this  backend.   A  value  of  128  requests
              maximally copious debug output; smaller levels reduce verbosity.

       Known bugs/limitations are:

              Brightness and contrast broken.
              The 600GS is grayscale only, and will lock up if you select color.  (Unfortunately,
              the 600GS and 600ZS are indistinguishable by software.)

       i.e. don't complain about these --- but if brightness and/or contrast  do  work  for  you,
       please tell me.

       If  your  scanner  locks  up,  try  setting  the  norealcal  or  noprecal  option  in  the
       configuration file (first one, then both), and see if it helps.  (If it does, report it.)

       Send lengthy bug reports and  new  scanner  information  to   All  bug
       reports  and  new  scanner  inquiries  should include an error log file.  You can generate
       copious stderr output by setting the SANE_DEBUG_MICROTEK  environment  variable  described
       above.  For example:

              setenv SANE_DEBUG_MICROTEK 128

       More  general  comments,  suggestions,  and inquiries about frontends or SANE should go to, the SANE Developers  mailing  list.  Have  a  look  at concerning subscription to sane-devel.
