how to limit a preview

I have installed sane 1.0.1 to access an
HP ScanJet 3c. In most cases, xscanimage
correctly scans in the color mode, at a
variety of sizes. But the 'acquire preview'
function fails only at the end of the scan,
failing to reset --- as a result, my system
hangs until I power cycle the scanner.

I find similar problems with greyscale and
lineart modes, which also do not terminate
properly.

This may simply be a problem with the
scanner hardware. However, since the color
mode works most times rather well, I could
use this scanner. But a preview would be
quite helpful.

My question is: can I somehow patch the
backend or elsewhere to force the preview
to terminate at a preset size?

Suggestions are welcome.
