[B]
The sorter transport motor [A] drives sorter transport roller [B] and exit roller
[C].
Because the paper transport speed of the sorter is different from the copier,
the sorter transport roller gear [E] and sorter exit roller gear [D] each have a
torque limiter to prevent roller marks on the copy.
