When the printer designates the finisher, the media diverter gate in the printer activates, and media is fed from 
the printer into the bridge unit assembly.
The bridge unit drive motor is activated by the trigger of the printer’s registration clutch, which drives the

transport)) and by the lower media exit roll assembly (driven by the drive motor (exit)).
When the first media reaches the compiler unit assembly, the media eject clamp motor is activated to lower the 
media eject clamp so that the media eject clamp and the media eject shaft assembly can clamp the...

When printing multiple sets, while stapling the first set on the compiler unit assembly or ejecting it to the stacker 
media bin, the first media of the second set will not be fed to the compiler unit assembly. 
When the first media of the second set reaches the finisher, the buffer diverter solenoid is activated by the 
printer command and by the sensor (finisher media entrance) to switch the buffer diverter gate.
Thus, the media route is switched...
