Changing the Document Feed Speed
When you scan using the Automatic Document Feeder, you can
select the document feed speed between low and fast. Normally,
you use the high speed mode. If you want to scan thick documents
or reduce noise of an image, use the low speed mode.
To change the document feed speed, lift the Automatic Document
Feeder and locate a switch as shown below. Slide the switch to
the circular mark position to use low speed, or to the other end to
use high speed.
