For staple or hole punch jobs, the diverter (from the printer or optional bin) under the
finisher
switches to open
up the paper path of the
finisher.
The diverter plunger controls the position of the diverter below it. The motor
(diverter) drives the movement of the plunger. The sensor (diverter plunger) detects the position of the plunger.
Paper enters the finisher through the entrance roller. The motor (SHPF transport) drives the entrance roller.
