       sane-microtek - SANE backend for Microtek scanners

       The  sane-microtek  library  implements a SANE (Scanner Access Now Easy) backend that pro-
       vides 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 (premliminary)
	      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 down-
       loadable 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
       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  scan-
       ner.  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.  noreal-
       cal  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.  Under UNIX, 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 vari-
	      able 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 configura-
       tion file (first one, then both), and see if it helps.  (If it does, report it.)

       Send lengthy bug reports and  new  scanner  information	to  mtek-bugs@mir.com.	 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
       sane-devel@mostang.com,	 the   SANE   Developers   mailing   list.   Have   a	look   at
