3.4.3 Switching the Separation Pressure
0013-3480
The DADF's separation assembly is equipped with a separation pressure switching mechanism which enables
switching between two settings (low or high).
The separation pressure may be switched by operating the separation pressure lever located in front of the
separation assembly. When the lever is operated, the position of the separation belt moves up or down to change
the amount of overlap in relation to the feeding roller, thereby varying the separation pressure.
MEMO:
The separation pressure lever is set to "Low" at time of shipment from the factory.
