NAME

       sane-microtek - SANE backend for Microtek scanners

DESCRIPTION

       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 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:

DEVICE NAMES

       This backend expects device names of the form:

	      special

       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

       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:

	      /dev/scanner
	      # this is a comment
	      /dev/sge

       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

       /etc/sane.d/microtek.conf
	      The backend configuration file (see also description of SANE_CONFIG_DIR below).

       /usr/lib64/sane/libsane-microtek.a
	      The static library implementing this backend.

       /usr/lib64/sane/libsane-microtek.so
	      The shared library implementing this backend (present on systems that support dynamic loading).

ENVIRONMENT

       SANE_CONFIG_DIR
	      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	configura-
	      tion  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 explic-
	      itly  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).

       SANE_DEBUG_MICROTEK
	      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

       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 exam-
       ple:

	      setenv SANE_DEBUG_MICROTEK 128
