sane-umax1220u - SANE backend for the UMAX Astra 1220U scanner
The sane-umax1220 library implements a SANE (Scanner Access Now Easy)
backend for the the UMAX Astra 1220U scanner.
For the latest information on this backend, please visit
UMAX ASTRA 2000U EXPERIMENTAL SUPPORT [Toc] [Back]
This backend can also drive the UMAX Astra 2000U (sort of). You will be
able to scan, but the colors will be horrible. From Stephane (the
author of sane-umax_pp), I learned that there are differences in the
way the color calibration is performed. It may be possible to use ideas
from that backend to add complete support for the 2000U to this backend.
Since I do not have access to an Astra 2000U, I do not plan to
work on this -- any volunteers?
The configuration file for this backend resides in
Its contents is a list of device names that correspond to UMAX Astra
1220U 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
When driving a Astra 2000U, use the product number 0x0030. See saneusb(5) for information on how to set the access permissions on the usb

(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 128 requests all debug output to be printed. Smaller levels reduce
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
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.

When reporting bugs, please run the backend with SANE_DEBUG_UMAX1220U
set to 10 and attach a copy of the log messages.
