● First Sheet
The finisher controller PCB moves the stapler according to the specified stapling position.
When the rear end of the first sheet passes the 1st delivery roller, the finisher controller PCB
stops the stack delivery motor (M102) and then rotates it in reverse.
The stack delivery motor rotates the stack delivery roller and return roller and delivers the
paper to the processing tray.
The paper in the processing tray is detected by the processing tray paper sensor (PI108).
When the paper is delivered to the processing tray, the swing motor (M106) starts and raises
the swing guide.
When the swing guide home position sensor (PI105) 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 (M103/M104)
starts and aligns the paper.
