TWAIN-SANE Scanner Drivers for Mac OS X

ubiquitin writes "The MacGIMP site has a story about TWAIN-SANE, which is a TWAIN datasource for Mac OS X that lets you use the SANE backend libraries. It means that most if not all of the the SANE project's long list of supported hardware can now be used on Mac OS X."

SANE

I thought Apple killed off SANE years ago! And what does the Standard Apple Numeric Environment have to do with scanners anyway??

I guess anyone still using it is in SANE.

A Word of Warning

Scanners are very stupid devices: they do EXACTLY what the driver tells them to do, up to and including:

• Scanning off the edge of the document.
• Overpowering the motor or lamp.
• Trying to go both ways at the same time (for dual-motor gigs).
• Feeding and ejecting paper at the same time in auto-loaders (thus destroying the document on dual-motor setups).

Reading the SANE site I see that they have encountered several of these in bugs and lost several scanners and documents in the process. Before you use this, check the site for what it can and will do for your scanner and read all the warnings Bad drivers can destroy scanners.

Most of the drivers are okay, but there's always one or two that will kick you.

Using an Epson or Mustek (If I'm not wrong) scanner will be a rather safe bet. These manufacturers are working with the Sane developers, so the drivers for these scanners will work as expected.
I myself use an Epson 1240 usb scanner, and it works great under Sane/Linux. The colors are better then with the Twain/Windows drivers that came with it.

Still has bugs to work out...

Having finally found a decent driver(?) for my CanoScan 656, I installed all the packages. While GraphicConverter acknowledges SANE, and the sane-find-scanner CLI tool detects my scanner, the scanimage command doesn't work. How the sane-find-scanner tool could work but not scanimage escapes me...

Your best bet is to ask for support on the Sane mailinglist at http://www.mostang.com/sane which is often very helpfull.
What's happening at your end, is that sane-find-scanner is a kernel utility, it can find the scanner that is being recognised by your kernel, for example a scsi or usb device. The scanimage tool uses the real Sane drivers to find a supported scanner. So in essence, your kernel finds your scanner, but for some reason the Sane libraries don't find a supported scanner. I'm definitely no Mac guru, but probably you have to tell Sane what device to look for, or which Sane driver to use. Or maybe enable/disable an option in your driver config. Or maybe rn the driver with debugging options. Anyway, your best bet is imo the Sane mailinglist for this. Slashdot is not the place to ask for this kind of support.
