NAME    [Toc]    [Back]

       sane-microtek - SANE backend for Microtek scanners

DESCRIPTION    [Toc]    [Back]

       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

	      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 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 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,  upto-date
	information  on  new releases and extraneous helpful hints are
       available from the backend homepage:

DEVICE NAMES    [Toc]    [Back]

       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.

CONFIGURATION    [Toc]    [Back]

       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.

FILES    [Toc]    [Back]

	      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).

ENVIRONMENT    [Toc]    [Back]

	      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

       SANE_DEBUG_MICROTEK    [Toc]    [Back]
	      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.

BUGS    [Toc]    [Back]

       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	 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

	      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  http://www.mostang.com/sane/mail.html  concerning
       subscription to sane-devel.
