From compiler unit assembly to stacker media bin
Stapled media on the compiler unit assembly (stapling mode) or aligned media (non-stapling mode) are held
between the media eject clamp and the media eject shaft assembly.
The media eject shaft assembly is driven by the media eject motor assembly to transfer media to the stacker
media bin.
After media is transferred to the stacker media bin, it is held by the clamp paddle attached to the media eject
shaft assembly.
From punch to upper media bin
The media to be ejected to the upper media bin is switched in the media path by the media diverter gate located
behind the punch and fed in the upper media transport roll assembly direction.
The media diverter gate is switched by the media diverter gate solenoid. While the solenoid is activated, media
is fed in the upper media transport roll assembly direction.
The two upper media transport roll assembly driven by the motor (buffer/transport) feed media to the upper
media exit roll assembly top at the top of the finisher.
The upper media exit roll assembly top driven by the drive motor (exit) to eject the media to the upper media bin.
The upper media exit roll assembly decelerates after a specified period of time from the following trigger events.
Functions of sensors along the media path
Bridge unit assembly
•
Sensor (bridge unit media entrance)
–
A photo-interrupter to detect whether media is fed from the printer to the bridge unit assembly
–
It turns “H” (+5 V dc) (light receiving) when media enters the bridge unit assembly.
•
Sensor (bridge unit media exit)
–
A photo-interrupter to detect whether media passes through the bridge unit assembly
–
It turns “H” (+5 V dc) (light receiving) when media reaches this sensor, and turns “L” (0 V dc) when
media exits from the bridge unit assembly.
•
Sensor (bridge unit top cover interlock)
–
A photo-interrupter to detect open/close of the bridge top cover assembly of the bridge unit assembly
–
It turns “H” (+5 V dc) (light receiving) when the bridge top cover assembly opens.
Sensor (bridge unit media entrance)
Sensor (bridge unit top
cover interlock)
Sensor (bridge unit media exit)
