	Hello,

	in order to avoid an issue due to simplescan/backend combination, can you 
try to scan just with scanimage ? In a command shell type the following 
command:

scanimage -d genesys --resolution 100 --mode Color >scan100dpi.pnm

The scan100dpi.pnm will hold a full area color scan at 100 dpi .

Regards,
	Stef
