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 scan‐
ners. 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 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:
Where special is the UNIX path-name for the special device that corre‐
sponds 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 scan‐
ner 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 acti‐
vated 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 config‐
uration 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 sepa‐
rator 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
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 indistinguish‐
able 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
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.
setenv SANE_DEBUG_MICROTEK 128
