sane-microtek - SANE backend for Microtek scanners
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 II, StudioScan IIsi
Agfa Arcus II (but not the "Arcus")
Agfa DuoScan (preliminary)
Vobis "Highscreen Realscan"
Microtek Color PageWiz (preliminary)
Transparent Media Adapter
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:
This backend expects device names of the form:
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/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 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
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 /usr/local/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
"/usr/local/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. dont complain about these --- but if brightness and/or contrast
do work for you, please tell me.
If your scanner locks up, try setting the
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
email@example.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
