Buffer Path Operation

1. Outline
This machine is provided with a buffer paper path for continuously receiving paper from the
host machine during stapling and job offset operation on the stapling tray. A maximum of three
copies (three originals or more in the stapling mode) are wrapped around the buffer roller. uring
this time, 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) is turned on so as to cause the sheet to wrap around the buffer
roller.
