[sane-devel] [HP3670] Black image after scan (GIT at 3c0b4649bd9a04d3f848d346b656bbbf3d39c7e1)

	Hello,

	I found a bug that explains the dark scans obtained. Even though the scanner 
didn't have shading calibration, scans were done with hardware shading 
correction enabled. Since no calibration data was sent before scan, we got 
black scans.
	I have committed a fix for it. Could you reset your testing tree to this 
version and give it a try ? I expect we will have some picture showing off.

Regards,
	Stef
