Booklet Finisher
The copy sent from the host machine is delivered to the ejection tray, processing tray, or
saddle stitcher according to the ejection type.
Job offset or stapling is performed, according to the instruction from the host machine, for
copy delivered to the 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 (M101), stack ejection motor (M102), and rear end assist motor (M109) 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 (PI103)
-Delivery path sensor (PI104)
Also, each ejection tray has sensors to detect the presence of copy on the tray.
-First tray paper sensor (PI111)
-Second tray paper sensor (PI112)
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).
