sane-microtek2 - SANE backend for Microtek scanners with SCSI-2 command
The sane-microtek2 library implements a SANE (Scanner Access Now Easy)
backend that provides access to Microtek scanners with a SCSI-2 command
set. This backend can be considered alpha to beta. Some scanner models
are reported to work well, others not. New development versions of this
backend can be obtained from http://home.t-online.de/home/karsten.fes-
There exists a different backend for Microtek scanners with SCSI-1 command
set. Refer to sane-microtek(5) for details.
And there is work in progress for the ScanMaker 3600. See
At present, the following scanners are known positively to work with

If you own a Microtek scanner other than the ones listed above, it may
or may not work with SANE! Because equal scanners are sold under different
names in different countries your model may be equivalent to one
of the above.
The parport scanners work with the ppscsi + onscsi kernel modules. See
The USB scanners work with the microtek kernel module. You may have to
add the vendor and model codes to microtek.c if they aren't yet listed
Both parport and USB scanners need the generic SCSI support, so check
if you have loaded the scsi_mod and sg modules!
If you try your scanner for the first time keep an eye on it. If it
gets commands that it doesn't understand the scanhead may go beyond the
scan area. The scanner then makes strange noises. In this case immedieately
switch off the scanner or disconnect its power cable to prevent
If your scanner is a different one than the models mentioned above and
it is working please tell the author about it. It would be nice if you
add a logfile to this information (creation of the logfile: see below).
If your scanner is not working properly you also should create a logfile
and send it to the author. He will use the information to improve
the backend and possibly make your scanner work.
How to create the logfile?
- put the line
"option dump 2" into your microtek2.conf
file or change the existing "option dump" to "2"
- in a terminal (bash) type
"export SANE_DEBUG_MICROTEK2=30" and then
"scanimage -l0 -t0 -x100 -y20 2>scan.log >sout.pnm"
You get two files: scan.log contains the logfile and sout.pnm
the scanned image (if there was scanned something). Zip them
This backend dynamically enables the options for the frontend, that are
supported by the scanner in dependence of the scanning-mode and other
options. Not supported options are disabled.
The following options are supported by the Microtek2-driver:
Color, grayscale, halftone and lineart scans.
Highlight, midtone, shadow, contrast, brightness, exposure time control,
gamma correction, threshold (dependent of the scan mode and the
Transparency media adapter, automatic document feeder
Additional options can be enabled or disabled in the microtek2.conf
file. See the configuration section of this manpage.
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.
The configuration file for this backend resides in
/etc/sane.d/microtek2.conf Its contents is a list of device names that
correspond to Microtek scanners with SCSI-2 interface. Empty lines and
lines starting with a hash mark (#) are ignored.
The configuration file may also contain options. Global options that
are valid for all devices are placed above the device names. Devicespecific
options are placed under the device name. Note that, except
for option dump <n> and option strip-height <n>, the entry in the
microtek2.conf file only enables the corresponding option for being
showed in the frontend. There, in the frontend, you can switch the
options on and off. Currently the following options are supported:
option dump <n>
option strip-height <n>
option no-backtrack-option <on/off>
option lightlid-35 <on/off>
option toggle-lamp <on/off>
option lineart-autoadjust <on/off>
option backend-calibration <on/off>
option colorbalance-adjust <on/off>
option dump <n> enables printing of additional information about the
SCSI commands that are sent to the scanner to stderr. This option is
primarily useful for debugging purpose. This option has to be a global
option and is best placed at the top of the microtek2.conf file.
If n=1 the contents of the command blocks and the results for the
INQUIRY and READ SCANNER ATTRIBUTES command are printed to stderr.
If n=2 the contents of the command blocks for all other SCSI commands
are printed to stderr, too. If n=3 the contents of the gamma table is
printed, too. If n=4 all scan data is additionally printed to stderr.
The default is n=1.
option strip-height <n> , where <n> is a floating point number, limits
the amount of data that is read from the scanner with one read command.
The unit is inch and <n> defaults to 1.0, if this option is not set in
the configuration file. If less than <n> inch of data fit into the SCSI
buffer, then the smaller value is used and this option has no effect.
If your system has a big SCSI buffer and you want to make use of the
whole buffer, increase the value for <n>. For example, if <n> is set to
14.0, no restrictions apply for scanners with a letter, legal or A4
sized scan area.
The following options enable or disable additional frontend options. If
an option is set to <on> an appropriate option will appear in the frontend.
option no-backtrack-option <on/off> prevents the scanner head from moving
backwards between the read commands. This speeds up scanning. Try
option lightlid-35 <on/off> If you use the LightLid-35 transparency
adapter you get an advanced option which switches off the flatbed lamp
during the scan.
option toggle-lamp <on/off> You get a button in the frontend where you
can switch on and off the flatbed lamp.
option lineart-autoadjust <on/off> You can tell the backend to try to
determine a good value for the lineart threshold.
option backend-calibration <on/off> Some scanners (e.g. Phantom 330CX
and 636CX) need to have calibrated the data by the backend. Try this
option if you see vertical stripes in your pictures.
option colorbalance-adjust <on/off> Some scanners (e.g. Phantom 330CX
and 636CX) need to have corrected the color balance. If this option is
enabled you get advanced options where you can balance the colors. And
you will have a button to use the values that the firmware of the scanner
A sample configuration file is shown below:
option dump 1
option strip-height 1.0
option no-backtrack-option on
# this is a comment
option lightlid-35 on
This backend also supports the new configuration file format which
makes it easier to detect scanners under Linux. If you have only one
scanner it would be best to use the following configuration file for
option dump 1
option strip-height 14.0
option no-backtrack-option on
option backend-calibration on
option lightlid-35 on
option toggle-lamp on
option lineart-autoadjust on
option colorbalance-adjust off

In this case all SCSI-Scanners should be detected automatically because

The static library implementing this backend.
The shared library implementing this backend (present on systems
that support dynamic loading).
If the library was compiled with debug support enabled, this
environment variable controls the debug level for this backend.
E.g., a value of 255 requests all debug output to be printed.
Smaller levels reduce verbosity. To see error messages on stderr
set SANE_DEBUG_MICROTEK2 to 1 (Remark: The whole debugging levels
should be better revised).
