Drives a large cam that alternately clamps and unclamps the lower
clamp roller, which is the idle roller of the clamp roller pair.
When these rollers are clamped, they are part of the paper feed path
and feed the stack toward the bottom fence of the fold unit. When the
idle roller is retracted, the stacks falls a very short distance (3 mm)
onto the fold unit bottom fence below. These rollers remain
unclamped while the bottom fence positions the stack for folding and
while the stack is folded by the fold rollers.
