Sane backend for the umax astra 1220u and similar scanners
The sane-umax1220 library implements a SANE (Scanner Access Now Easy) backend for the the UMAX Astra 1220U and similar scanners.
For more information on this backend, please visit http://umax1220u-sane.sourceforge.net/.
This backend is also able to drive the UMAX Astra 1600U/2000U/2100U. The 2100U is confirmed to work. For the other scanners no reports have been received yet. Please contact us and tell us if your scanner works ([email protected]).
Usually, no manual configuration is necessary. The configuration file for this backend resides in /etc/sane.d/umax1220u.conf.
Its contents is a list of device names that correspond to UMAX Astra scanners. Empty lines and lines starting with a hash mark (#) are ignored. A sample configuration file is shown below:
#usb vendor product usb 0x1606 0x0010 # Device list for non-linux systems /dev/scanner /dev/usb/scanner0
See sane-usb(5) for information on how to set the access permissions on the usb device files.
The backend configuration file:
/etc/sane.d/umax1220u.conf
The static library implementing this backend:
/usr/lib/arch_triplet/sane/libsane-umax1220u.a
The shared library implementing this backend:
/usr/lib/arch_triplet/sane/libsane-umax1220u.so (present on systems that support dynamic loading)
SANE_DEBUG_UMAX1220U
If the library was compiled with debug support enabled, this environment variable controls the debug level for this backend. E.g., a value of 128 requests all debug output to be printed. Smaller levels reduce verbosity:
SANE_DEBUG_UMAX1220U values
Number Remark 1 print failures 2 print information 3 print high-level function calls 4 print high-level function checkpoints 9 print mid-level function calls 10 print mid-level function checkpoints 80 print protocol-level function entry 90 print protocol-level function exit
Example:
export SANE_DEBUG_UMAX1220U=10
600 dpi scanning may fail for large image sizes.
If you keep getting I/O errors, try cycling the power on your scanner to reset it.
There is no way to cancel a scan, since the driver ignores sane_cancel().
If you try scanning an image which is too small, you will get I/O errors. Be sure to adjust the scan area before doing a scan, since by default, the scan area is zero.

This backend isn't actively maintained. Nevertheless, bug reports and comments should be sent to the sane-devel mailing list. When reporting bugs, please run the backend with SANE_DEBUG_UMAX1220U set to 10 and attach a copy of the log messages.
