[sane-devel] Unstable scanning with Fujitsu fi-7160

[m. allan noah]

I suspect the scanner may be going to sleep. Some older models had problems
waking up. Questions:

1. what other model scanners have the problem?
2. how long do you wait between scans when this happens?
3. if you press a button on the scanner before you scan, does the problem
happen?
4. Have you tried another computer?

if you want, you could gather some logs and send them to me.

SANE_DEBUG_FUJITSU=15 scanimage [your parameters here] 2>7160.log
