staple tray.
When ejecting from the processing tray, rear end assist guide is used in addition to the stack ejection roller to eject
the stack.
The inlet motor (M31), stack ejection motor (M32), and rear end assist motor (M39) are step motors. These motors
are rotated forward or backward by the microcomputer (CPU) in the finisher controller PCB.
The following two sensors are provided in the copy delivery path to detect the arrival or passing of copies.
• Inlet sensor (PI33)
• Delivery path sensor (PI34)
Also, each ejection tray has sensors to detect the presence of copy on the tray.
• First tray paper sensor (PI42)
• Second tray paper sensor (PI43)
If the copy does not reaches or passes each sensor within prescribed time, the finisher controller PCB determines that
the jam has occurred and stops the operation. Then it notifies the host machine that a jam has occurred. When all of
the doors are closed after fixing the jam, the finisher checks whether copy is detected by any of the above two sensors
(inlet sensor, delivery path sensor). If any of the sensors detects a copy, the finisher determines that the jam is not
fixed and sends jam processing signal to the host machine once more.
