11.2.2.3. Punch Mechanism
11.2.2.3.1. Paper Transport Stop Mechanism
Stops the paper momentarily at the punching position.
Process
The leading edge of the paper being transported into the Finisher passes through the Paper Feed Sensor.
• Punch Registration Clutch is turned ON.
When the normally closed type CL1 is turned ON, the driving force to the Registration Roller is cut off,
stopping the paper at the Registration Roller.
• Papers are transported from the printer continuously. The leading edge of the paper is pressed against
the nip of the Registration Roller, which allows positioning of each paper. The Guide Plate, equipped with
a spring moves downward to compensate for the paper loop created during this process.
• The leading edge of the paper is punched by the Punch Unit.
• CL1 is turned OFF, the driving force is transmitted to the Registration Roller, and the paper is transported.
11.2.2.3.2. Punch Unit Drive Mechanism
Punch Unit is composed of Guide A, B, Punch Bar, Cam, Cam Lifter, Drive Shaft, and Single Punch Clutch
(CL2).
11.2.2.3.3. Punch Unit Drive
When the Transport Motor is driven, the Punch Unit’s drive gear rotates the Punch Unit’s clutch gear.
But the driving force is not transmitted to Drive Shaft because the Punch Clutch (CL2) is normally OFF and
locked.
When CL2 is turned ON and the lock is released, the clutch gear’s rotation is transmitted to the drive and
the drive shaft is rotated.
(CL2 is turned ON momentarily, and locks after one rotation, stopping the movement of the shaft)
A rotation of the Drive Shaft causes a single vertical movement of the Punch Bar which is supported by the
Cam, thus punching the paper.
