II. FEED/DRIVE SYSTEM
A.
Outline
The finisher is designed to operate according to the commands from its host machine to deliver
arriving copies to trays in the appropriate mode: simple stacking, job offset, stapling.
See Figure 2-201 for a diagram of the three modes of delivery (four for the Saddle Finisher).
