Yes. Unfortunately the time is specified by the scanner, the backend 
just does what the scanner asks for. If the backend sends any 
commands before the warming up is completed the scanner will return 
an error. 

There's probably some way to shorten the warming up phase of the 1670, 
but I haven't a clue how to do it.

That sounds like a different problem. Please run

SANE_DEBUG_SNAPSCAN=255 xsane 2>debug.log

and send me the debug.log file for such an error.
