11.1.2.2.10. Buffer Path Operation
This machine is provided with a buffer paper path for continuously receiving paper from the Copier during
stapling and stack job offset operation on the Stapling Tray. A maximum of three copies (three originals or
more in the staple mode) are wrapped around the Buffer Roller. During this time, stack job offset and
stapling are performed on the Stapling Tray.
The following shows operation on the buffer paper path.
1. When the first sheet arrives, the Buffer Inlet Solenoid (SL2) remains off.
The first sheet enters the buffer path.

2. When the leading edge of the sheet has moved past the Buffer Path Inlet Paper Sensor (PI17), the
Buffer Outlet Solenoid (SL3) turns on so as to cause the sheet to wrap around the Buffer Roller.

3. When the leading edge of the sheet has moved past the Buffer Path Paper Sensor (PI14), the Buffer
Roller stops and waits for the second sheet.
