	Hello,

	this sheet-fed scanner needs to be calibrated to provide bets results. In 
SANE 1.0.22, this scanner (usb 0x0458 0x2021) is described as using a 
"cism216.fw" firmware. Did you extract the one you are using from the windows 
driver installer ? Is the usb id different ?
	gt68xx.conf lets you tune the analog frontend (afe), see sane-gt68xx man 
page.

Regards,
	Stef
