13:
With the feed of the stack halted, the fold plate [1] retracts. The fold plate HP sensor (not
shown) detects the fold plate and stops it at its home position.

The fold rollers [2] and fold unit exit rollers [3] begin to rotate together and feed out the
folded booklet to the lower tray.
15:
Once the trailing edge of the stack passes the fold unit exit sensor [4], the clamp rollers [5]
close to be ready to feed the next stack. The fold unit bottom fence [6] descends. The
bottom fence HP sensor [7] stops the bottom fence when it detects the actuator on the
bottom fence.
