2.4.2 Pickup Operation

a. Operations
The following pickup operations will take place when a stack of originals is placed on the
original tray and the Start key is pressed:
1) Pickup Separation
The paper stopper plate is moved down, and the paper retaining plate is moved down to
the stack; then, the bottommost original is picked up.
After pickup, the original is moved between the separation belt and the
feed roller to prevent double-feeding.
