What is this page about?
On this page you find information about the sane-umax backend of the
This backend supports most UMAX SCSI scanners and some scanners of other
vendors. It does not support any USB or parallel-port scanners.
To find out if your scanner is supported by the sane-umax backend take a look
at the Documentation or take a look at the
Note that there is a sane-umax1220u backend that supports some ohter UMAX scanners.

The reader_process is handled by sanei_thread instead of fork() now.
This version of sane-umax also works on Mac OS X.
Information about the Astra 2100SU and Astra 4000U
Since sane-umax-1.0.7-build 33 (and any further version) the
UMAX Astra 2200 (SU) is supported via USB.
With some changes in the USB routines it could be possible
to support the Astra 2100 SU and the Astra 4000U.
I just got a USB-Snoopy protocoll of the
Astra 4000U and it looks like the Astra 4000U uses the
same data structures like the UMAX SCSI scanners. This
does not mean that the scanner already is supported. It only
means that (after a lot of work) it may be supported by the sane-umax backend.
I still do not have any information about the Astra 2100 SU.
