Since my previous posting, Mr. Ellert has published new backends. The current version is 3.2. I downloaded and installed his files, but my computer still won't see the Astra 1220U scanner.
I found somewhere online an instruction to add the scanner in the "Printer & Scanner" System Preference. But my System Preferences does not see the scanner.
In contrast the SANE System Preference does seem to show the driver installed:
Does anyone have any ideas on how to get this scanner to talk to my computer?
I have followed Mr. Ellert's recomendation to use Terminal:
Start the Terminal application (it should be located in the Utilities folder within the Applications folder), then type in the Terminal window the command:
scanimage > test.pnm
Terminal does scan my documents. But Terminal is rather limited as a scanning application. My scanner won't work with Image Capture or Vue Scan. Both of those applications report that they cannot find the scanner. And the "Printer & Scanner" Preference does not see the scanner, either.
Any gueses as to how to get a proper scanner application to see the scanner?
Update. In Terminal I tried "scanimage -L" and got this:

device `umax1220u:libusb:004:002' is a UMAX Astra 1220U flatbed scanner
I do not know much about these matters. Does anyone know how to get System Preferences, Image Capture, or Vue Scan to see the scanner?
