roller (lower) does not rotate because the stack ejection lower roller clutch (CL32) is disengaged. The paper in the
processing tray is detected by the processing tray paper sensor (PI38).
When the paper is delivered to the processing tray, the swing motor (M36) starts and raises the swing guide. When
the swing guide home position sensor (PI35) detects the rising of the swing guide, the swing guide motor stops and
holds the swing guide at the raised position.
After the processing tray paper sensor detects the paper, the aligning motor (M33/M34) starts and aligns the paper.
■ Last Sheet
When alignment of the last sheet completes, the finisher controller PCB moves the aligning plate to alignment
position with the aligning motor (M33/M34) (with the paper held with the aligning plate). Then the finisher controller
PCB staples at the specified staple position.
After stapling, the finisher controller PCB starts the swing motor (M36) and lowers the swing guide. Then the stack
is ejected by the stack delivery roller, return roller, and rear endassist guide.
