[sane-devel] Pixma MP600R times out after scan stats

Thu May 7 19:17:12 UTC 2009

Phil, 

This behavior when scanning at high dpi is a classic of many Pixma
devices, but there are some slight differences between models. 

This is probably easy to fix, as code for this purpose is already
present in the backend for other Pixma devices, but before, could you
send a small sample image (send directly the image, not the logs) to see
exactly how it needs to be tuned up.
