Paper Feed Mechanism-2 (Manual)

When the ADF / Manual Feed Selector is set to "MANUAL", the Retard Roller is free from the Separation Roller. In this case, the
Retard Roller does not operate as the document separation.
6.3. Paper Feed Mechanism-3 (ADF Adjustment)
This ADF Adjustment (1,2,3, or 4 on ADF ADJ.) will enable this scanner to realize the continuous scanning properly by forcing an
appropriate pressure from the Retard Roller to Separation Roller according to the document quality.
The mechanism is as follows.
With the increasing of turning angle for ADF knob counterclockwise, the cam pressure to the spring in the direction of the arrow (1)
grows to enable the Retard Roller to press the Separation Roller in the direction of the arrow (2).
This force and torque limiter the Retard Roller has originally will help the scanner feed only a single document.
