When the finisher is designated by the command of printer, 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 printer's registration clutch on to drive the transport belts
in the bridge unit assembly. The motor power is transmitted to the two belts between bridge unit right shaft
assembly and bridge unit left shaft assembly.
The media fed to the bridge unit assembly is securely held between the transport belts and the pinch rolls, and
fed to the finisher.
