sane-abaton - SANE backend for Abaton flatbed scanners
library implements a SANE (Scanner Access Now Easy)
backend that provides access to Abaton flatbed scanners. At present, only the
Scan 300/GS (8bit, 256 levels of gray) is fully supported, due to the absence
of programming information. The Scan 300/S (black and white) is recognized,
but support for it is untested.
If you own a Abaton scanner other than the ones listed above that works with
this backend, or if you own an Abaton scanner that does not work with this
backend, please contact email@example.com
model number, so that arrangements can be made to include support for it. Have
a look at http://www.sane-project.org/mailing-lists.html concerning
subscription to sane-devel.
Abaton is out of business, and these scanners are not supported by Everex (the
parent company of Abaton), nor is there any programming information to be
found. This driver is therefore based on information obtained by running
Abaton's scanning desk accessory under MacsBug and tracing the MacOS SCSI
Manager calls it made during image acquisition.
However, the protocol is very similar to, though not compatible with, the one
used by the Apple scanners, therefore, if this backend is ever extended to
support the other Abaton models (they also made a color flatbed scanner), it
may be possible to fill in some "missing pieces" from the (quite
detailed) Apple scanner documentation.
This backend expects device names of the form:
is the path-name for the special device that corresponds to
a SCSI scanner. For SCSI scanners, the special device name must be a generic
SCSI device or a symlink to such a device. Under Linux, such a device name
takes a format such as /dev/sga
, for example. See
sane-scsi(5) for details.
The contents of the abaton.conf
file is a list of device names that
correspond to Abaton scanners. Empty lines and lines starting with a hash mark
(#) are ignored. See sane-scsi(5) on details of what constitutes a valid
- 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 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.
There are a few known ones, and definitely some unknown ones.
- Scan area miscalculations
- For the sake of programmer efficiency, this backend handles all
measurements in millimetres, and floors (rather than rounds) values to
avoid possible damage to the scanner mechanism. Therefore, it may not be
possible to scan to the extreme right or bottom edges of the page.
- Cancelling the scan
- This might not work correctly, or it might abort the frontend. The former
is more likely than the latter.
If you have found something that you think is a bug, please attempt to recreate
it with the SANE_DEBUG_ABATON environment variable set to 255, and send a
report detailing the conditions surrounding the bug to
- Implement non-blocking support
- Finish reverse-engineering the MacOS driver
- This will allow me to add support for other models with reasonable
confidence that it will work, as well as to fully exploit the information
returned by the INQUIRY command.

The sane-abaton backend was partially written by David Huggins-Daines, based on
the sane-apple backend by Milon Firikis.
