	Hello,

	regarding frontend handling, I'm currently meeting the same kind of issue 
than you for the HP3670 which is a GL646 based scanner. I get black scans 
while everything else seems correctly set. It is using different addresses 
than supported models. I'll share my findings with you.
	Patches -even experimental or just for comments- are welcomed.

Regards,
	Stef
