	these PDF are freely available from the genesys corporate site or from 
various datasheet providers. Have you tried to check the exact chip used by 
the G4010 ? The G4050 I am currently working on is using a gl843. I am going 
to commit code to bring 200 and 300 dpi scans for it. It will be interesting 
to see how it behaves with the G4010.
	BTW, when the scanning head of the G4050 is away from its parking 
position, I can clearly see the GL843 printing on the PCB inside the scanner. 
May be you could try to look at it to check it is also GL843 based.
