[sane-devel] Subsequent scans timeout with Canon imageClass MF4150

[Dan Duvall]

Hey there,

I'm having trouble scanning using the pixma backend with a Canon imageClass MF4150 over USB. The first scan always seem to succeed while subsequent attempts timeout.

These are the commands I'm running.

SANE_DEBUG_PIXMA=256 scanimage 2> pixma_debug-success.log
SANE_DEBUG_PIXMA=256 scanimage 2> pixma_debug-timeout.log

stderr of each:
https://gist.github.com/4551560
https://gist.github.com/4551574

I get this same behavior using sane-backends 1.0.22 on Debian lenny, and 1.0.24 on OS X 10.8.2.

Any suggestions on how to further debug?

Thanks!
Dan
